Like most engine components, spark plugs experience wear over time and eventually need replacement, but fortunately this is a repair you can do on your own.

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?
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 Chevrolet for the 2010 Suburban 2500. Of course, if you drive your vehicle more aggressively or own a Suburban 2500 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 early, such as:
- Problems starting your engine
- Rough idle
- Engine misfiring
Note that this list is certainly not comprehensive, and these problems on their own do not necessarily 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 regular maintenance, and you are definitely doing so with the responsible decision to replace your Chevrolet Suburban 2500’s spark plugs on a regular basis.
Changing spark plugs on a 2010 Chevrolet Suburban 2500
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 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 ordinary tools you probably 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 definitely have in your toolbox if you do not already.
- 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 garage. You will want to check your FSM (factory service manual) or owner’s manual to determine the correct torque rating to use when putting in the new spark plugs for your 2010 Chevrolet Suburban 2500 to be sure they are installed properly.
- 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 a problem. This tool can help you diagnose the exact 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 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 comes in handy for quite a few other jobs.
Tips for changing spark plugs on your 2010 Chevrolet Suburban 2500
Ensure you reference the video above before you attempt to repair the spark plugs on your 2010 Chevrolet Suburban 2500, as well as review your factory service manual. Additionally, we have some tips below here to help you as you complete this repair.
- 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 Suburban 2500 or any other vehicle.
- You should replace spark plugs on a cold engine. Ensure you wait at least 30 minutes after any kind of operation before attempting to replace the spark plugs on your 2010 Chevrolet Suburban 2500
- 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.
- It’s not a bad idea to use dielectric grease when installing new spark plugs. You can apply a a very light coating 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.
- 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.
