GM 4.3L (262 cu in) firing order — diagram & guide

Mastering the balance of power with the gm 4.3l firing order..

After the 3.8-liter engine seized in production, the new 4.3-liter V6 replaced it as an upgraded version of the six-cylinder. It managed to stick along for various models and production years, but there’s one thing that all the versions of the engine have in common – the GM 4.3L (262 cu in) firing order .

That’s why our team wanted to help with accurate information on the firing sequence and the cylinder configuration. This guide will walk you through the usage of the firing order so you can maintain your engine’s spark plugs and coils.

GM 4.3L firing order

The most important thing to note is that the GM 4.3L firing order is 1-6-5-4-3-2, and this is crucial for properly inspecting the engine’s cylinders. What’s more, most modern-day GM’s V6 engines come with a 1-2-3-4-5-6 firing order, so it’s crucial to differentiate between those two.

Once you get to know the firing sequence, the next step would be to properly apply it. We’ll help with that as well by guiding you through the engine’s configuration and cylinder positions.

GM 4.3L cylinder diagram

Well, the good news is – the 4.3-liter V6 is pretty simple in terms of cylinder configuration. There are cylinders 1, 3, and 5 on the left bank and 2, 4, and 6 on the right bank of the engine. All are easily accessible and the only important thing to note is that the engine is transversely placed or “rotated” in the engine bay.

This means that the left bank of the engine is actually the upper row of the cylinders near the windshield, while the lower bank is in fact the right cylinder bank. It’s important to note the rotation of the engine before applying the firing order.

GM 4.3L vehicle applications

The GM 4.3-liter V6 has appeared in numerous variations in different vehicle models, so we’ve decided to bring you a complete list of all of them:

• Chevy Silverado
• Chevy Impala

So, if you own any of these cars along with the Astro minivan, the firing order for your 4.3-liter V6 engine would be 1-6-5-4-3-2.

Well, that wraps it up for our guide on the GM 4.3-liter V6 firing order, and our team hopes you’ll find it helpful for properly maintaining your car.

We also hope that information regarding the cylinder arrangement of the engine will be useful to you when identifying the cylinders, so feel free to rely on our guide for the steps.

• Page 46 For example, in a crash at only 25 mph (40 km/h), a 12-lb. (5.5 kg) baby will suddenly become a 240-lb. (110 kg) force on a person’s arms. A baby should be secured in an appropriate restraint. Children ..ho are up against, or very close to, any air bag when it inflates can be seriously injured or killed.
• Page 47 What are the different types of add-on child restraints? Add-on child restraints, which are purchased by the vehicle’s owner, are available in four basic types. Selection of a particular restraint should take into consideration not only the child’s weight, height and age but also whether or not the restraint will be compatible with the motor vehicle in which it will be used.

In a crash, an infant in a rear-facing seat settles into the restraint, so the crash forces can be distributed across the strongest part of an infant’s body, the back and shoulders.
• Page 50 People should never hold a baby in their arms while riding in a vehicle. A baby doesn’t weigh much until a crash. During a crash a baby will become so heavy not possible to hold For example, in a crash at only 25 mph (40 km/h), a 12-lb.

Page 51: Child Restraint Systems

• Page 52 A forward-facing child seat (C-E) provides restraint for the child’s body with the harness and also sometimes with surfaces such as T-shaped or shelf-like shields. A booster seat (F-G) is a child restraint designed to improve the fit of the vehicle’s safety belt system. Some booster seats have a shoulder belt positioner, and some high-back booster seats have a five-point harness.
• Page 53 How do child restraints work? A child restraint system is any device designed for use in a motor vehicle to restrain, seat, or position children. A built-in child restraint system is a permanent part of the motor vehicle. An add-on child restraint system is a portable one, which is purchased by the vehicle’s owner.

Page 55: top strap.

• Page 56 In Canada, the law requires that forward-facing child restraints have a top strap, and that the strap be anchored. In the United States, some child restraints also have a top strap. If your child restraint has a top strap, it should be anchored. Anchor the top strap to one of the following anchor points.

Page 59: Lower Anchorages And Top Tethers For Children (Latch System)

• Page 60 With this system, use the LATCH system instead of the vehicle’s safety belts to secure a child restraint. If a LATCH-type child restraint isn’t attached to its anchorage points, the restraint won’t be able to protect the child correctly. In a crash, the child could be seriously injured or killed.

Page 71: Where Are The Air Bags

• Page 72 The right front passenger’s air bag is in the instrument panel on the passenger’s side. If something between an occupant and an air bag, the bag might not inflate properly or might force the object into that person causing severe injury or even death. The path of an inflating air bag must be kept clear.

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!

Chevy 5.3 Firing Order [Cylinder Numbers With Diagrams]

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.

There was actually a recall for this. Go to your local GMdealer and have them check your VIN for a recall. If not under recall get out of there its easy to repair yourself don't let'em fool you.Remove the front pads caliper and rotors. Locate the abs sensor mounted to the wheelbearing assembly by a small socket head cap screw (Allen wrench). Removethe bolt and softly gently/wiggle the abs sensor around until it pops upout of the hole. some will break, which is why it wouldbe nice if the recall applies to your vehicle that way if they break gm replaces. Once you get both sides removed, clean themounting surface of all rust or build up with w-d 40 and small steel toothbrush then wipe off excess with clean rag and mild soap and warm water, dry completely make sure no spray residue exist on parts, Next apply a thin layer of lubricant grease to preventfuture rusting and reassemble.The rust build up under the sensor is causing the angle to change resultingin inaccurate wheel speed readings in the abs module your abs module will interprets this asa wheel is either slipping or skidding and applies your abs. This should make you happy with no more irritations. Please rate me. If you need further assistance you can always ask me. Good luck with this.
