Ensure you purchase the correct number of spark plugs for your engine corresponding to the number of cylinders. Often, manufacturers will bundle spark plugs in quantities that make it impossible to buy the exact amount you need for your engine.

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 in today’s market at an affordable price.
How often should I change my spark plugs?
As a general recommendation, 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 GMC for the 1996 Savana 1500. Of course, if you drive your vehicle more aggressively or own a Savana 1500 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 prematurely, such as:
- Rough idle
- Problems starting your engine
- Engine misfiring
As a quick note, keep in mind that this list is certainly not comprehensive, and these problems on their own do not definitively point to the spark plugs being the solitary 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 GMC Savana 1500’s spark plugs on a regular basis.
Changing spark plugs on a 1996 GMC Savana 1500
This is a process you can do on your own with some ordinary 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.
As noted before, you should be able to complete a spark plug change with some regular tools you most 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 commonplace tools that you should for sure have in your toolbox if you do not already.
- A spark plug tester – this is definitely a niche tool, but it can save you a ton 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 torque wrench is a very important tool to have in your garage. You will want to check your factory service manual to determine the correct torque rating to use when inserting the new spark plugs for your 1996 GMC Savana 1500 to be sure they are installed properly.
- 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 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 for sure 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 helpful for a decent number of other jobs.
Tips for changing spark plugs on your 1996 GMC Savana 1500
Be sure to reference the video above before you attempt to repair the spark plugs on your 1996 GMC Savana 1500, as well as review your factory service manual. Be sure to check the tips shown here to help you as you perform this repair.
- 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 beginning, remove the negative terminal of your battery. You should always disconnect the battery anytime you work on the electrical system of your GMC Savana 1500 or any other vehicle.
- Your engine should be completely cold before you replace your spark plugs. You should wait at least 30 minutes after any kind of operation before attempting to replace the spark plugs on your 1996 GMC Savana 1500
- 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 lessens the chance of voltage leak and helps avoid the misfortune of the boot fusing to the spark plug over time.
- 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.
