Maintaining your vehicle is an incredibly rewarding task and learning how to replace your spark plugs is a great place to start. There’s a good probability you will be required to replace your set of spark plugs several times while you own a a 2013 Chevrolet Tahoe. Spark plugs are one of the most important parts inside your engine as they start the entire combustion process that starts and keeps your engine running for many thousands of miles. Like most engine components, spark plugs experience wear over time and eventually need replacement, but fortunately this is a repair you can do yourself. Chances are, if you’ve found yourself here, you have no idea how to do that, or potentially 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 about 20-45 minutes. This article will go over everything you’ll need to know about your Chevrolet Tahoe’s spark plugs, whether you need some baseline information or a full, step-by-step guide to performing a spark plug change.
Correct spark plugs on a 2013 Chevrolet Tahoe
CHAMPION 401[/caption]For any 2013 Chevrolet Tahoe, you can use CHAMPION 401 spark plugs. These will be an exact fit and will match the required specifications of your engine. As this 2013 Chevrolet Tahoe features an 8 cylinder engine, ensure you purchase 8 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 in today’s market 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 2013 Tahoe. Of course, if you drive your vehicle more aggressively or own a Tahoe 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 potentially need a spark plug replacement earlier than the recommended schedule, such as:
- Rough idle
- Engine misfiring
- Problems starting your engine
As a quick note, keep in mind 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 routine maintenance, and you are definitely doing so with the responsible decision to replace your Chevrolet Tahoe’s spark plugs on a regular basis.
Changing spark plugs on a 2013 Chevrolet Tahoe
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
- 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 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 a decent number of other jobs.
- A set of spark plug sockets – These come in very handy because many standard sockets are not deep enough for spark plugs. Also, 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 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 definite problem.
- A torque wrench is a very important tool to have in your collection. You will want to check your factory service manual to determine the correct torque rating to use when installing the new spark plugs for your 2013 Chevrolet Tahoe to be confident they are installed properly.
Tips for changing spark plugs on your 2013 Chevrolet Tahoe
- 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.
- You might consider using dielectric grease when installing new spark plugs. You can apply a a little bit 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.
- Before beginning, 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 Tahoe or any other vehicle.
- You should replace spark plugs on a cold engine. Wait at least 30 minutes after any kind of operation before attempting to replace the spark plugs on your 2013 Chevrolet Tahoe
- 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 light coating of anti-seize to the threads of their spark plugs, especially on older vehicles.
