One of the most important aspects of vehicle maintenance is ensuring your spark plugs are in good working order. There’s a decent chance you will need to replace your old spark plugs several times over the course of owning a 1999 Chevrolet K3500 Pickup. Spark plugs are one of the most vital components inside your engine as they begin the entire combustion process that starts and keeps your engine running for many thousands of miles. Like most engine components, spark plugs experience wear over time and eventually need replacement, but fortunately this is a repair you can do yourself. Odds are, if you’ve found yourself here, you have no idea how to do that, or potentially you’d just like to know what kind of spark plugs you need to buy. The complete process of changing your spark plugs should take approximately 20-45 minutes. This article will go over everything you will need to know about your Chevrolet K3500 Pickup’s spark plugs, whether you need some baseline information or a full, step-by-step guide to performing a spark plug change.

How often should I change my spark plugs?
Generally, it is advised that you replace spark plugs once every 20,000 to 40,000 miles. Of course, please make sure to check your owner’s manual to determine the exact interval determined by Chevrolet for the 1999 K3500 Pickup. Of course, if you drive your vehicle more aggressively or own a K3500 Pickup with some modifications, you may want to consider changing your spark plugs closer to the 20,000 miles end of that spectrum.
However, there are also telltale signs of a car that may potentially need a spark plug replacement earlier than the recommended schedule, such as:
- Problems starting your engine
- Rough idle
- Engine misfiring

Changing spark plugs on a 1999 Chevrolet K3500 Pickup
This is a process you can do on your own with some commonplace garage tools. Of course, consult your owner’s manual, as well as a factory service manual (FSM for short) or an equivalent Haynes or Chiltons manual. The video shown below does a good job of outlining the process.
Helpful Tools
- A spark plug tester – this is definitely a niche tool, but it can save you lots of time. Although we’ve discussed spark plug replacement being a good thing to replace regularly and not just when issues occur, you may also be replacing your spark plugs because of something going wrong. This tool can help you diagnose the definite problem.
- A spark plug gap tool. This allows you to check the gap of your spark plugs and increase or decrease it if necessary. Most plugs will come pregapped, but if this is not the case, you should absolutely have one of these.
- I also highly recommend you have a feeler gauge as it makes it a bit easier to check the exact gap, and it is helpful for countless other jobs.
- A set of spark plug sockets – These come in very handy because many standard sockets are not deep enough for spark plugs. In addition, some spark plug holes are a bit smaller, so it requires a thinner wall like the one featured in the product here to fit. The linked product also features a magnet to keep a good hold of the spark plug so you do not drop it into your engine bay!
- A torque wrench is a essential tool to have in your toolbox. You should check your factory service manual to determine the correct torque rating to use when installing the new spark plugs for your 1999 Chevrolet K3500 Pickup to be sure they are installed properly.
Tips for changing spark plugs on your 1999 Chevrolet K3500 Pickup
- Note that this is not official advice as many spark plug manufacturers advise against the use of anti-seize. However, I have heard from numerous old-school mechanics that they always apply a tiny amount of anti-seize to the threads of their spark plugs, especially on older vehicles.
- One of the most important things to remember is to avoid overtightening the plugs or worse, cracking them due to overtightenting. Use a torque wrench capable of lower, more precise torque ratings to be sure that you don’t make this mistake.
- It isn’t a bad idea to use dielectric grease when installing new spark plugs. You can apply a a small dab to the inside of the boot and the ceramic part of your spark plugs. It prevents voltage leak and helps avoid the misfortune of the boot fusing to the spark plug over time.
- First, remove the negative terminal of your battery. It’s a good idea to disconnect the battery anytime you work on the electrical system of your Chevrolet K3500 Pickup or any other vehicle.
- Your engine should be cold before you replace your spark plugs. Wait at least 30 minutes after your engine has been running before attempting to replace the spark plugs on your 1999 Chevrolet K3500 Pickup
