1997 Chevrolet Cavalier Spark Plug Replacement Guide

by

There’s a good chance you will need to replace your worn out spark plugs several times over the course of owning a 1997 Chevrolet Cavalier. Spark plugs are one of the most vital parts inside your engine as they begin the entire combustion process that starts and keeps your engine running for many thousands of miles. Similar to most engine components, spark plugs experience wear over time and eventually need to be replaced, 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 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. This article will go over everything you should need to know about your Chevrolet Cavalier’s spark plugs, whether you need some general information or a full, step-by-step guide to performing a spark plug change.

Correct spark plugs on a 1997 Chevrolet Cavalier

ACDelco Gold 6 RAPIDFIRE Spark Plug (Pack of 1)For any 1997 Chevrolet Cavalier, you can use ACDELCO 6 spark plugs. These will be an exact fit and will match the required specifications of your engine. As this 1997 Chevrolet Cavalier features a 2.4L L4 engine, ensure you purchase 4 spark plugs. We always try to recommend the best possible spark plugs for the money, and these spark plugs are either a factory recomendation or an equivalent replacement available now at a reasonable price.

How often should I change my spark plugs?

Very 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 1997 Cavalier. Of course, if you drive your vehicle more aggressively or own a Chevrolet Cavalier 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 needs a spark plug replacement earlier than the recommended schedule, such as:

  • Problems starting your engine
  • Engine misfiring
  • Rough idle

Consider that this list is absolutely not comprehensive, and these problems on their own do not necessarily point to the spark plugs being the standalone culprit. However, the best way to prevent any issues with your vehicle is to take care of it with routine maintenance, and you are definitely doing so with the responsible decision to replace your 1997 Chevrolet Cavalier’s spark plugs on a regular basis.

Changing spark plugs on a 1997 Chevrolet Cavalier

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 (FSM for short) or an equivalent Haynes or Chiltons manual. The video shown below does a good job of outlining the process.

Helpful Tools

As noted before, you should be able to complete a spark plug change with some regular tools you likely already have. However, there are a few tools that are specific to this job that you may not have, and we also want to recommend some general tools that you should for sure have in your toolbox if you do not already.

  • A spark plug gap tool. This allows you to check the gap of your spark plugs and modify it if necessary. Most plugs will come pregapped, but if this is not the case, you should definitely have one of these.
  • A torque wrench is a essential tool to have in your toolbox. You should 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 1997 Chevrolet Cavalier to be confident they are installed properly.
  • 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 exact problem.
  • 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!

Tips for changing spark plugs on your 1997 Chevrolet Cavalier

Be sure to watch the video above before you attempt to repair the spark plugs on your 1997 Chevrolet Cavalier, as well as review your FSM (factory service manual). Additionally, we have some tips below here to help you as you perform this repair.

  • First, disconnect the negative terminal of your battery. It is wise to disconnect the battery anytime you work on the electrical system of your Chevrolet Cavalier or any other vehicle.
  • Your engine should be completely 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 1997 Chevrolet Cavalier
  • 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.
  • It isn’t a bad idea to use dielectric grease when installing new spark plugs. You can apply a small amount 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.
  • During this process, one of the most vital things to ensure you do 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.
