It is imperative that you ensure your spark plugs are in good condition. There’s a decent probability you will be required to replace your old and worn out spark plugs several times during your ownership of a 1995 Chevrolet Lumina APV. 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 parts and components, spark plugs experience wear over time and eventually need to be swapped out for new replacements, but fortunately this is a repair you can do on your own. Odds are, if you’ve found yourself here, you have no idea how to do that, or perhaps you’d just like to know what kind of spark plugs you need to buy. The entire process of changing your spark plugs should take roughly 20-45 minutes.

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 1995 Lumina APV. Of course, if you drive your vehicle more aggressively or own a Lumina APV 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 prematurely, such as:
- Engine misfiring
- Rough idle
- Problems starting your engine
Consider that this list is certainly not comprehensive, and these problems on their own do not definitively point to the spark plugs being the standalone culprit.

This is a process you should be able to do on your own with some ordinary 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 set of spark plug sockets – These come in extremely handy because many standard sockets are not deep enough for spark plugs. Additionally, 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 will want to check your FSM (factory service manual) or owner’s manual to determine the correct torque rating to use when installing the new spark plugs for your 1995 Chevrolet Lumina APV to be sure 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 this is not the case, you should definitely have one of these.
- I also highly recommend you have a feeler gauge as it makes it a bit more straightforward to check the exact gap, and it is useful for countless other jobs.
- 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.
Tips for changing spark plugs on your 1995 Chevrolet Lumina APV
- You should replace spark plugs on a cold engine. Wait at least 30 minutes after your engine has been running before attempting to replace the spark plugs on your 1995 Chevrolet Lumina APV
- 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.
- 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 tiny amount of anti-seize to the threads of their spark plugs, especially on older vehicles.
- Before you begin, remove the negative terminal of your battery. You should always disconnect the battery anytime you work on the electrical system of your Chevrolet Lumina APV or any other vehicle.
- You might consider using 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 lessens the chance of voltage leak and helps avoid the misfortune of the boot fusing to the spark plug over time.
