After the latch has been released, push the seatback toward the front of the vehicle until it locks in place. To raise the seatback, unlock the seatback latch by pushing up on the lever while pushing down on the upper edge of the seatback.

Page 19: Rear Seats

Page 20 To adjust your seatback, pull up on the lever located on the lower outside of the seat. To raise or lower the center console, press the button located between the beverage holders. Sit in the center seating position only when the console is in an upright and locked position.
Page 21 Removing the Rear Seats To remove the rear seats, do the following: 1. If you are removing the center seat, remove the right lap To do this, press the tip of a key into the release hole of the safety belt attachment while pulling up on the safety belt.
Page 22 5. Lift up on the left and the right seat release levers at the same time. The latches are near the floor on the rear legs of the seat. 1-10 6. Lift up on the rear of the seat to remove the seat assembly from the rear latch pins.

Page 30: how to wear safety belts properly.

Page 31 3. Pick up the latch plate and pull the belt across you. Don’t let it get twisted. 4. Push the latch plate into the buckle until it clicks. Pull up on the latch plate to make sure it is secure. If the belt isn’t long enough, see “Safety Belt Extender”...
Page 32 Shoulder Belt Height Adjuster Before you begin to drive, move the shoulder belt adjuster to the height that is right for you. 1-20 To move it down, push in at the top of the arrows and move the height adjuster to the desired position. You can move the adjuster up just by pushing up on the shoulder belt guide.
Page 33 What’s wrong with this? The shoulder belt is too loose. It won’t give nearly as much protection this way. CAUTION: You can be seriously hurt if your shoulder belt is too loose. In a crash, you would move forward too much, which could increase injury. The shoulder belt should fit against your body.
Page 34 What’s wrong with this? The belt is buckled in the wrong place. 1-22 CAUTION: You can be seriously injured if your belt is buckled in the wrong place like this. In a crash, the belt would go up over your abdomen. The belt forces would be there, not at the pelvic bones.
Page 35 What’s wrong with this? The belt is over an armrest. CAUTION: You can be seriously injured if your belt goes over an armrest like this. The belt would be much too high. In a crash, you can slide under the belt. The belt force would then be applied at the abdomen, not at the pelvic bones, and that could cause serious or fatal injuries.
Page 36 What’s wrong with this? The shoulder belt is worn under the arm. It should be worn over the shoulder at all times. 1-24 CAUTION: You can be seriously injured if you wear the shoulder belt under your arm. In a crash, your body would move too far forward, which would increase the chance of head and neck injury.
Page 37 What’s wrong with this? The belt is twisted across the body. CAUTION: You can be seriously injured by a twisted belt. In a crash, you wouldn’t have the full width of the belt to spread impact forces. If a belt is twisted, make it straight so it can work properly, or ask your dealer to fix it.

Page 38: Safety Belt Use During Pregnancy

Page 39: right front passenger position.

Page 40 CAUTION: Air bags inflate with great force, faster than the blink of an eye. If you’re too close to an inflating air bag, as you would be if you were leaning forward, it could seriously injure you. Safety belts help keep you in position before and during a crash.
Page 41 How the Air Bag System Works Where are the air bags? The driver’s air bag is in the middle of the steering wheel. The right front passenger’s air bag is in the instrument panel on the passenger’s side. 1-29...
Page 42 CAUTION: If something is between an occupant and an air bag, the bag might not inflate properly or it might force the object into that person. The path of an inflating air bag must be kept clear. Don’t put anything between an occupant and an air bag, and don’t attach or put anything on the steering wheel hub or on or near any other air bag covering.
Page 43 What makes an air bag inflate? In an impact of sufficient severity, the air bag sensing system detects that the vehicle is in a crash. The sensing system triggers a release of gas from the inflator, which inflates the air bag. The inflator, air bag and related hardware are all part of the air bag modules inside the steering wheel and in the instrument panel in front of the right front passenger.
Page 44 Air bags are designed to inflate only once. After they inflate, you’ll need some new parts for your air bag system. If you don’t get them, the air bag system won’t be there to help protect you in another crash. A new system will include air bag modules and possibly other parts.
Page 45 Servicing Your Air Bag-Equipped Vehicle Air bags affect how your vehicle should be serviced. There are parts of the air bag system in several places around your vehicle. You don’t want the system to inflate while someone is working on your vehicle. Your dealer and the service manual have information about servicing your vehicle and the air bag system.

Page 46: Rear Seat Passengers

Page 47 3. If the belt stops before it reaches the buckle, tilt the 4. To make the lap part tight, pull down on the buckle latch plate and keep pulling until you can buckle it. end of the belt as you pull up on the shoulder part. Pull up on the latch plate to make sure it is secure.
Page 48 The lap part of the belt should be worn low and snug on the hips, just touching the thighs. In a crash, this applies force to the strong pelvic bones. And you’d be less likely to slide under the lap belt. If you slid under it, the belt would apply force at your abdomen.

Page 49: Rear Safety Belt Comfort Guides For Children

Page 50 2. Slide the guide under and past the belt. The elastic cord must be under the belt. Then, place the guide over the belt, and insert the two edges of the belt into the slots of the guide. 1-38 3. Be sure that the belt is not twisted and it lies flat. The elastic cord must be under the belt and the guide on top.

Page 51: Center Passenger Position (Bench Seat)

Page 52 When you sit in a center seating position, you have a lap safety belt, which has no retractor. To make the belt longer, tilt the latch plate and pull it along the belt. 1-40 To make the belt shorter, pull its free end as shown until the belt is snug.

Page 53: Children

Page 54 CAUTION: Never hold a baby in your arms while riding in a vehicle. A baby doesn’t weigh much crash. During a crash a baby will become so heavy you can’t hold it. For example, in a crash CAUTION: (Continued) 1-42 CAUTION: (Continued) at only 25 mph (40 km/h), a 12 will suddenly become a 240...
Page 55 Smaller Children and Babies (Cargo Vans) CAUTION: Children who are up against, or very close to, any air bag when it inflates can be seriously injured or killed. Air bags plus lap shoulder belts offer the best protection for adults, but not for young children and infants.
Page 56 CAUTION: Never hold a baby in your arms while riding in a vehicle. A baby doesn’t weigh much until a crash. During a crash a baby will become so heavy you can’t hold it. For example, in a crash at only 25 mph (40 km/h), a 12 lb.

Page 57: Child Restraints

Page 58 A rear facing infant restraint (B) positions an infant to face the rear of the vehicle. Rear facing infant restraints are designed for infants of up to about 20 lbs. (9 kg) and about one year of age. This type of restraint faces the rear so that the infant’s head, neck and body can have the support they need in a frontal crash.
Page 59 A forward facing child restraint (C E) positions a child upright to face forward in the vehicle. These forward facing restraints are designed to help protect children who are from 20 to 40 lbs. (9 to 18 kg) and about 26 to 40 inches (66 to 102 cm) in height, or up to around four years of age.

Page 60: Where To Put The Restraint

Page 61 CAUTION: A child in a rear facing child restraint can be seriously injured or killed if the right front passenger’s air bag inflates. This is because the back of the rear facing child restraint would be very close to the inflating air bag. Always secure a rear facing child restraint in a rear seat.

Page 62: Top Strap

Page 63 If your vehicle is a passenger van with rear seats, a child restraint with a top strap should only be used in the second or third row. Don’t use a child restraint with a top strap in the right front passenger’s position because there’s no place to anchor the top strap.

Page 64: Securing A Child Restraint In A Rear Outside Seat Position

Page 65 3. Buckle the belt. Make sure the release button is positioned so you would be able to unbuckle the safety belt quickly if you ever had to. 4. To tighten the belt, pull up on the shoulder belt while you push down on the child restraint. If you’re using a forward facing child restraint, you may find it helpful to use your knee to push down on the child...
Page 66 Securing a Child Restraint in a Center Seat Position (Bench Seat) You’ll be using the lap belt. Be sure to follow the instructions that came with the child restraint. Secure the child in the child restraint when and as the instructions say.
Page 67 4. Buckle the belt. Make sure the release button is positioned so you would be able to unbuckle the safety belt quickly if you ever had to. 5. To tighten the belt, pull its free end while you push down on the child restraint. If you’re using a forward facing child restraint, you may find it helpful to use your knee to push down on the child...

Page 68: Front Seat Position

Page 69 1. Because your vehicle has a front passenger air bag, always move the seat as far back as it will go before securing a forward facing child restraint. (See “Seats” in the Index.) 2. Put the restraint on the seat. 3.
Page 70 5. Pull the rest of the lap belt all the way out of the retractor to set the lock. 1-58 6. To tighten the belt, feed the lap belt back into the retractor while you push down on the child restraint. You may find it helpful to use your knee to push down on the child restraint as you tighten the belt.

Page 71: Larger Children

Page 72 1-60 CAUTION: Never do this. Here two children are wearing the same belt. The belt can’t properly spread the impact forces. In a crash, the two children can be crushed together and seriously injured. A belt must be used by only one person at a time. What if a child is wearing a lap but the child is so small that the shoulder belt is very close to the child’s face or neck?
Page 73 CAUTION: Never do this. Here a child is sitting in a seat that has a shoulder belt, but the shoulder part is behind the child. If the child wears the belt in this way, in a crash the child might slide under the belt. The belt’s force would then be applied right on the child’s abdomen.

Page 74: Safety Belt Extender

Page 75: replacing restraint system parts after a crash.

Page 76 Section 2 Features and Controls Here you can learn about the many standard and optional features on your vehicle, and information on starting, shifting and braking. Also explained are the instrument panel and the warning systems that tell you if everything is working properly and what to do if you have a problem.
Page 77 Keys CAUTION: Leaving children in a vehicle with the ignition key is dangerous for many reasons. A child or others could be badly injured or even killed. They could operate the power windows or other controls or even make the vehicle move. Don’t leave the keys in a vehicle with children.
Page 78 This vehicle has one double ignition and door locks. It will fit with either side up. When a new vehicle is delivered, the dealer provides the owner with a pair of identical keys and a bar The bar coded tag has a code on it that tells your dealer sided key for the or a qualified locksmith how to make extra keys.

Page 85: battery replacement, page 86: sliding door, page 87: sliding door security lock.

Page 88 CAUTION: If your vehicle is facing downward on a steep grade (15 percent or more), the door may not stay open and could slam shut, possibly injuring someone. To make sure the door does not slam shut, be sure to hold it open until everyone is clear of the door, and only then allow it to slowly close.
Page 89 Hatch CAUTION: It can be dangerous to drive with the rear swing out windows, rear hatch or rear doors open because carbon monoxide (CO) gas can come into your vehicle. You can’t see or smell CO. It can cause unconsciousness and even death. If you must drive with the rear swing windows, rear hatch or rear doors open or if electrical wiring or other cable connections must...
Page 90 To lock the power lock system from the outside, insert the key in the hatch release button and turn it clockwise. All doors will lock. Also, see the Caution following “Hatch” located in this section. Theft Vehicle theft is big business, especially in some cities. Although your vehicle has a number of theft features, we know that nothing we put on it can make it impossible to steal.
Page 91 Passlock Your vehicle is equipped with the Passlock theft deterrent system. Passlock is a passive theft deterrent system. Passlock enables fuel if the ignition lock cylinder is turned with a valid key. If a correct key is not used or the ignition lock cylinder is tampered with, fuel is disabled.

Page 92: Ignition Positions

Page 93 NOTICE: If your key seems stuck in LOCK and you can’t turn it, be sure you are using the correct key; if so, is it all the way in? If it is, then turn the steering wheel left and right while you turn the key hard.
Page 94 NOTICE: Holding your key in START for longer than 15 seconds at a time will cause your battery to be drained much sooner. And the excessive heat can damage your starter motor. Wait about 15 seconds between each try to help avoid draining your battery or damaging your starter.
Page 95 Engine Coolant Heater (If Equipped) In very cold weather, 0 _ F 18 _ C) or colder, the engine coolant heater can help. You’ll get easier starting and better fuel economy during engine warm up. Usually, the coolant heater should be plugged in a minimum of four hours prior to starting your vehicle.

Page 96: Automatic Transmission Operation

Page 97 Ensure the shift lever is fully in PARK (P) before starting the engine. Your vehicle has an automatic transmission shift lock control system. You have to fully apply your regular brakes before you can shift from PARK (P) when the ignition key is in RUN. If you cannot shift out of PARK (P), ease pressure on the shift lever shift lever all the way into PARK (P) as you maintain brake application.
Page 98 DRIVE (D): This position is for normal driving. If you need more power for passing, and you’re: Going less than about 35 mph (55 km/h), push your accelerator pedal about halfway down. Going about 35 mph (55 km/h) or more, push the accelerator pedal all the way down.

Page 99: Parking Brake

Page 100 NOTICE: Driving with the parking brake on can cause your rear brakes to overheat. You may have to replace them, and you could also damage other parts of your vehicle. If you are towing a trailer and are parking on a hill, see “Towing a Trailer”...
Page 101 1. Hold the brake pedal down with your right foot and set the parking brake. 2. Move the shift lever into PARK (P) like this: Pull the lever toward you. 2-26 Move the lever up as far as it will go. 3.

Page 182: Defensive Driving

Page 183: drunken driving.

Page 184 It’s the amount of alcohol that counts. For example, if the same person drank three double martinis (3 ounces or 90 ml of liquor each) within an hour, the person’s BAC would be close to 0.12 percent. A person who consumes food just before or during drinking will have a somewhat lower BAC level.
Page 185 The body takes about an hour to rid itself of the alcohol in one drink. No amount of coffee or number of cold showers will speed that up. “I’ll be careful” isn’t the right answer. What if there’s an emergency, a need to take sudden action, as when a child darts into the street? A person with even a moderate BAC might not be able to react quickly enough to avoid the collision.

Page 187: anti-lock brakes (abs).

Page 188 Here’s how anti lock works. Let’s say the road is wet. You’re driving safely. Suddenly an animal jumps out in front of you. You slam on the brakes. Here’s what happens with ABS. A computer senses that wheels are slowing down. If one of the wheels is about to stop rolling, the computer will separately work the brakes at each front wheel and at both rear wheels.

Common V8 Firing Orders, Distributor Locations and Rotation Directions

There’s little as frustrating as finishing up a build and not remembering the firing order so you can install the plug wires and fire it up.

Of course, most of us know the firing order for our own ride and others we’re familiar with, but that doesn’t help much when you’re a Ford guy and you’re helping a buddy finish up and fire-off his Cadillac.

This table shows Firing Order, Distributor Rotation Direction, and Cylinder Banks.

Technical Note: All American V8s have offset cylinder banks to accommodate side-by-side rod pairing on the crank throws. In the absence of published information, the number one cylinder will almost always be the one that is farthest forward regardless of which bank it is on.

The exception to this rule is the Pontiac V8 where the forward most cylinder is on the passenger side. The number one cylinder is still on the front left side, but it is not the most forward cylinder on the block.

Chevy 5.3 Firing Order [Diagram & Cylinder Numbers]

There’s so much you need to know about the Chevy 5.3 firing order! What is the purpose of a firing order? Why is a firing order important? How do you determine a firing order? And more.

For anyone who may be confused about the 5.3 LS firing order, this post is for you. It will help you gain an understanding of where each cylinder should fire and when – so that, if something goes wrong, you’ll have a better idea of what’s going on and what you can do about it. Read on.

Chevy 5.3 Firing Order

In short, The firing order on a 5.3 LS engine is 1-8-7-2-6-5-4-3. This means, the spark plug at number one cylinder (1) fires first, then number eight (8), and so on.

The distributor rotates in a clockwise direction, which means that when viewed from above, it rotates counterclockwise.

The number one spark plug fires first, followed by the remaining spark plugs in their respective order. It is best to always check the owner’s manual for your vehicle to find out the specific firing order.

5.3 LS firing order Diagram

What Does the Term Firing Order Mean?

The firing order is the sequence in which each cylinder in a multi-cylinder engine is timed to fire. The firing order is specified by the engine manufacturer based on certain factors that affect the performance of the engine, such as vibration and smoothness.

The firing order is expressed in the form of a series of numbers, designating the cylinder number to which the ignition should occur for each power stroke. The order may be clockwise or counterclockwise, depending on the particular engine design. You can find out what is the firing order for your type of engine here.

In the video below, the host discusses engine firing order and its importance. He illustrates the firing order patterns and discusses the implications of swapping firing orders. The video covers how firing order affects engine performance, particularly in terms of cylinder pairing, intake charge, exhaust pulse, and bearing wear.

What is the Purpose of it?

The purpose of firing order is to achieve smoother engine operation through the smoothing process in the combustion chamber. In other words, firing order is essential for strong yet smooth engine operation.

The firing order determines the sequence of power strokes, which is why the correct firing order is essential. A misfire in an engine can lead to catastrophic damage to the connecting rods or pistons or both, and if a driver continues running an engine with a misfire it can cause a severe backfire.

The firing order is set so that the forces on the connecting rods are balanced and so that the vibrations produced by each piston are evenly spaced out.

Why is a firing order important?

Firing order is important because each cylinder has a certain amount of time to complete its combustion cycle before the next cylinder begins its cycle.

When the engine gets out of time, it will run rough and have other issues. Firing order is also important in determining the power stroke of a 4-stroke engine.

A 4-stroke engine will produce power every other revolution of the crankshaft, so if the firing order is configured properly, the power strokes will combine to provide smooth power output.

Firing order is everything when it comes to a running engine. If you don’t get it right, nothing will work properly. As such, if you’re working on a car, better make sure that you’ve got it right before you start removing things and replacing them.

How Do You Determine it on a Chevy?

The firing order on a car engine is determined by the number of cylinders contained within that engine. There are two basic types, where either cylinder number one is the first to be fired or cylinder number one is the last to be fired.

Either way, it’s determined by the crankshaft, which governs which cylinder receives fuel when the piston starts moving up the cylinder.

It’s determined by the pressure exerted on each side of the piston and how long it takes for this pressure to equalize, allowing both sides of the piston to move at the same time.

Now that you know the Chevy 5.3 firing order, you will always be able to take care of your vehicle and fix engine problems before they get bad enough to warrant a call to a mechanic.

Keep this information handy so that it’s there when you need it. If you have any questions regarding the Chevy 5.3 firing order, kindly leave a comment below.

What causes a misfire condition.

What Tests Can I Perform To Find The Cause Of The Misfire Condition?
What Tools Do I Need To Test The Misfire Code(s)?
Is This Something I Can Do? Or Do I Need To Take It To A Repair Shop?
Where Do I Find The Test Articles?

A misfire condition, in non technical terms simply describes an engine that is not running on all cylinders.

This condition is also best described by other common terms: 'engine has a dead cylinder' or 'engine has a miss' or 'engine has a rough idle'.

Whether your GM vehicle has a V6 or a V8, if one cylinder or two cut out, it won't run on 100% engine power and this will cause some of the following consequences (symptoms):

The check engine light (CEL) will be on.
P0300 Random Cylinder Misfire.
P0301 Cylinder #1 Misfire.
P0302 Cylinder #2 Misfire.
P0303 Cylinder #3 Misfire.
P0304 Cylinder #4 Misfire.
P0305 Cylinder #5 Misfire.
P0306 Cylinder #6 Misfire.
P0307 Cylinder #7 Misfire.
P0308 Cylinder #8 Misfire.
Sometimes, even tho' the engine is suffering a bonafide misfire, no misfire codes are registered in the computer's memory and/or no check engine light (CEL) on.
Lack of power upon acceleration.
Smell of unburned gas exiting the tail pipe.
Rough idle and may stall.
Cranks but does not start.
Will not pass the emissions tests.
Bad gas mileage.

What complicates things a little further, is that your specific vehicle may come equipped with a TBI (Throttle Body Injection) or a CPI (Central Port Injection) or a CSFI (Central Sequential Fuel Injection) fuel system but in reality, all of the misfires, irrespective of the type of fuel or ignition system, have common root causes.

Since quite a few things can cause and engine to misfire, we need to understand the basics of what each engine cylinder needs to create power. Now, don't worry, I won't go into minute technical detail, just the basics (and in plain English) that you need to troubleshoot your misfire issue.

The most important thing you need to know is that each cylinder needs air, fuel, and spark to produce power. So, let's take a look at how each one is delivered to the engine:

Ignition System: The ignition system is responsible for the production and delivery of spark. The ignition system is usually the culprit behind a misfire.

The usual suspects (that cause a misfire, rough engine idle, engine miss, 'dead' cylinder, etc.) are:

Bad spark plugs.
Bad spark plug wires.
Bad distributor cap.

The good news is that all of the components that make up the ignition system can be tested, and at the end of the article I'll show you where to find the 'How To' test articles.

Fuel System: The fuel system is responsible for the delivery of fuel. If fuel is missing from any one specific engine cylinder, it will misfire.

GM in all its wisdom decided to use a fuel injector assembly (affectionately referred to as the 'Spider') that sits inside the intake manifold plenum. When this bad boy starts to fail (by leaking fuel inside the plenum), it will cause a misfire condition.

Engine Mechanical Condition: The pistons and valves are the ones that draw air into the engine. Usually all cylinders wear out evenly but every now and then, either thru' lack of maintenance or some mechanical problem, you'll have one or more wear out at an accelerated pace.

To make the long story short, those cylinders (with accelerated wear and tear) to produce a less than average compression value that will cause a misfire condition.

Other issues, that can not be overlooked are vacuum leaks.

1996 Astro - firing order

Add to quote

I have a misfire on #3. Have had this van since brand new with 150K miles, well taken care of, but now it mainly sits in the driveway with a cover on it. I drive it when I want to pickup stuff from the hardware store, about 400 miles/year. When I fill the tank, I would also add a bottle of Techron. It started misfiring when damp and throwing codes, but after running for awhile would smooth out and SES would clear. Now it has a pretty solid misfire on #3. The plugs/wires only have 20K miles (but 10 years!) on them. Put in a new distributor cap and looking to replace the wire on #3. I have the original factory repair manuals but could not find anywhere in them how to identify the cylinders. I don't want to put a lot of effort into this, so if replacing the #3 wire does not fix it, it will probably be time to sell it and move on. anyone interested in buying it? never had any body repair done, very little rust (other than the battery pan!).

IIRC it's 1-6-5-4-3-2. Driver side front is 1, middle 3, rear 5. Passenger side front 2, middle 4, rear 6.

Thanks!

Getting a little behing during preparations for holidays. Not panicing yet. I remember that the manual was incorrect when it came to firing order. Also remember that Olds was different the Chev as to which cylinder was #1 etc. Anyone have the correct firing order and cylinder layout handy that they could share with me? Thanks Regards Gary Zingle

Garry, 1-8-4-3-6-5-7-2 Front of coach --------- | 1 2 | | 3 4 | | 5 6 | | 7 8 | --------- Since this is from my notes, I probably wrote it there because there is a mistake in the FSM.

Fritz, Distributor rotation in the manual is backwards. Correct rotation is counterclockwise.

Oops. I said clockwise intending to show "correct" numbering order on subject diagram (exchange the plug wires 3 and 6 numbers). Distributor rotation IS counterclockwise as the manual states. Nothing like killing one bird with two stones. Fritz > Fritz, > > Distributor rotation in the manual is backwards. Correct rotation is > counterclockwise. > > Patrick > >> >> >>> Front of coach >>> --------- >>> | 1 2 | >>> | 3 4 | >>> | 5 6 | >>> | 7 8 | >>> --------- >>> >>> Since this is from my notes, I probably wrote it there >> because there is a >>> mistake in the FSM. >>> >>> HTH, >>> Patrick >> >> My notes show the error to be in the distributor cap plug >> wire numbering, >> since my 455 firing order picture is correct, as stated by Patrick. >> (p.6Y-50, 75-76 M.M.) >> Manual diagram shows plug wires 3 and 6 reversed. >> Should be wired (in clockwise sequence) 1-2-7-5-6-3-4-8. >> >> HTH >> Fritz Washburn >> 77 Kingsley >> Twin Cities >>

Gary, If you are referring to the distributer, yes it is different than a Chevy. #1 is the 5:00 position.

Thanks to all that wrote All the reference I found in my manuals as to firing order are correct. The reference on 6Y 50 does not show distributor rotation but the numbering is correct. Thanks. I feel better about connecting the wires now. My manuals are only a year old. Maybe the error was corrected in these later printings? Thanks. Regards Gary Zingle 1973 GMC 26 foot

Chevrolet 7.4L (454 cu in) firing order — diagram & guide

Experience the artistry behind the chevrolet 7.4l firing order..

One of the best things about Chevy is that they not only developed small block V8 engines but also some impressive big block engines along the way. As automotive enthusiasts, we love the old-school Chevy trucks with a 454 engine, so if you have one we salute you.

However, we believe that you’ve at least experienced misfire issues once before, so you’ll need to know about the Chevrolet 7.4L (454 cu in) firing order to prevent one in the future. Don’t worry, though, as our team of seasoned automotive experts will lead you through it for both L21 and L29 engines.

Chevrolet 7.4L L29 firing order

The Chevrolet 7,4L L29 firing order is 1-8-4-3-6-5-7-2 and this was the first version of Chevy’s 7.4-liter V8 engine. In fact, this firing order doesn’t only apply to the 454 cu in engine, but also to other big block Chevy V8s such as the 396, 427, and 502.

However, the fact that there are two versions of the 7.4-liter engine made drivers a bit worried that they will use a wrong firing order when dealing with the engine, so let’s see if there’s any difference.

Chevrolet 7.4L L21 firing order

The Chevrolet L21 engine is also a 7.4-liter V8, only this time it was more oriented towards commercial use than for heavy-duty vehicles. To give you a straight-up answer, the Chevy 7.4L L21 firing order is 1-8-4-3-6-5-7-2, which is exactly the same as for the L29.

Moreover, these engines don’t only share the same engine block, but also the majority of other components, so it’s not a surprise that the firing order is also the same. Even so, there are some slight differences between these that may require different maintenance steps.

The most notable ones include forged pistons and crankshaft, so these were considered to be much more durable than the L29 engine, especially on higher revs.

Chevrolet 7.4L cylinder diagram

A white car with a number of numbers on the hood.

For most of Chevy’s V8 engines, we have two cylinder banks with four cylinders each. However, unlike big block V8s from other manufacturers, Chevy uses a specific pattern with cylinders 1, 3, 5, and 7 being in the “odd” bank, and cylinders 2, 4, 6, and 8 being in the “even” bank.

So, it’s the same case with this engine as you’ll find the odd cylinder bank on the the driver’s side and the even one on the passenger’s side.

Chevy 7.4L vehicle applications

Now that we’ve cleared up some differences between the two versions of this engine, it’s time to give you a rough idea of all the models that come with it:

Chevy Suburban
Chevy Express

The L21 version also came with some vehicles like the Chevy Motorhome or the GMC TopKick, so the engine was also used in a few other models except for Chevy.

Overall, the firing order for the 7.4-liter big block V8 is the same as for other V8s that Chevy made at that time, so we hope to have helped clear that out. On top of all that, make sure to pay attention to the cylinder arrangement in this engine as it’s not the standard one you’d expect out of a V8.
