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 specific interval determined by Chevrolet for the 1996 K2500 Pickup. Of course, if you drive your vehicle more aggressively or own a K2500 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 classic signs of a car that may need a spark plug replacement earlier than the recommended schedule, such as:
- Problems starting your engine
- Rough idle
- Engine misfiring
Note that this list is of course not comprehensive, and these problems on their own do not necessarily point to the spark plugs being the solitary culprit.

Changing spark plugs on a 1996 Chevrolet K2500 Pickup
This is a process you can do on your own with some standard garage tools. Of course, consult your owner’s manual, as well as a factory service manual 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 an issue. This tool can help you diagnose the exact problem.
- A set of spark plug sockets – These come in extremely 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 vital tool to have in your arsenal. You should check your factory service manual to determine the correct torque rating to use when putting in the new spark plugs for your 1996 Chevrolet K2500 Pickup to be certain they are installed properly.
- 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 not, 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 useful for quite a few other jobs.
Tips for changing spark plugs on your 1996 Chevrolet K2500 Pickup
- Before starting, 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 K2500 Pickup or any other vehicle.
- Take this (unofficial advice) lightly 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 small amount of anti-seize to the threads of their spark plugs, especially on older vehicles.
- The most important thing 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.
- Your engine should be cold before you replace your spark plugs. Ensure you wait at least 30 minutes after your engine has been running before attempting to replace the spark plugs on your 1996 Chevrolet K2500 Pickup
- 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.
