How to Change Spark Plugs on a 2017 Chevy Silverado

Changing the spark plugs on your 2017 Chevy Silverado is a straightforward maintenance task that can greatly enhance engine performance and fuel efficiency. Here’s a step-by-step guide to help you through the process:

Tools Required:

  • Ratchet and socket set (10mm and 5/8" sockets)
  • Torque wrench
  • Extension bar (if needed)
  • New spark plugs (check your manual for the correct type)
  • Spark plug gapping tool
  • Anti-seize lubricant
  • Compressed air (optional, for cleaning)
  • Gloves and safety goggles (for protection)

Steps to Change Spark Plugs:

1. Prepare Your Vehicle

  • Ensure the engine is cool before starting. This prevents burns and makes the process easier.
  • Disconnect the negative battery terminal to avoid any electrical issues.

2. Locate the Spark Plugs

  • Open the hood and find the engine cover; some may need to be removed to access the spark plugs.
  • The spark plugs are typically located on the top of the engine, in line with the ignition coils.

3. Remove the Ignition Coils

  • Carefully disconnect the electrical connectors from each ignition coil.
  • Unbolt the ignition coils using a 10mm socket and remove them. Keep them in a safe place for reinstallation.

4. Clean the Area

  • Use compressed air to blow any debris away from the spark plug wells. This prevents dirt from entering the combustion chamber.

5. Remove the Old Spark Plugs

  • Use a spark plug socket with an extension to unscrew the old spark plugs.
  • Turn counterclockwise to remove each spark plug. If they’re stuck, gently wiggle the socket while turning.

6. Prepare the New Spark Plugs

  • Before installing, check the gap on the new spark plugs with a spark plug gapping tool. Adjust if necessary.
  • Apply a small amount of anti-seize lubricant to the threads of the new spark plugs to facilitate future removal.

7. Install the New Spark Plugs

  • Carefully screw in the new spark plugs by hand to avoid cross-threading.
  • Once hand-tight, use the torque wrench to tighten them to the manufacturer’s specification. This is typically around 15 lb-ft for most models.

8. Reinstall the Ignition Coils

  • Place the ignition coils back in their respective positions and tighten the screws.
  • Reconnect the electrical connectors to each ignition coil, ensuring they click into place.

9. Reconnect the Battery

  • Reattach the negative battery terminal, ensuring the connection is secure.

10. Test Your Vehicle

  • Start the engine and let it idle for a few minutes. Check for any unusual sounds and ensure the engine runs smoothly.

Tips:

  • It’s recommended to replace spark plugs every 30,000–50,000 miles, but refer to your owner’s manual for specific intervals.
  • If you encounter any issues or notice engine misfires after replacement, double-check your work to ensure everything is properly connected.

Isn’t it funny how changing spark plugs can turn into a whole operation? I sometimes feel like I’m performing surgery on my truck! But honestly, you guys nailed the tools list. It’s all about preparation.

My wife says I’m like a doctor when I work on my truck, but she also wonders why I need so many tools! Just to change spark plugs? Just wait until I tell her it could take a couple of hours! LOL.

If you run into trouble, don’t panic! Spark plugs usually come with their own specifications for torque. And if you’re unsure, YouTube guides are a lifesaver—just watch a couple of videos before you start.

Absolutely! Videos can give you a great visual guide. What brand of spark plugs would you all recommend for the Silverado?

Definitely stick to AC Delco for the 2017 Silverado. They work best with GM vehicles! I’ve seen mixed reviews on others. Just make sure you follow the proper gap settings too; it makes a difference.

Great tip! Also, don’t skip the dielectric grease application; it prevents corrosion. Makes removing them next time much easier!

Changing spark plugs on a 2017 Chevy Silverado is straightforward. Start by gathering your tools: a socket wrench, a spark plug socket, and some anti-seize compound. Make sure the engine is cool and the battery disconnected for safety. Remove the engine cover if needed.

Great tips, moondavid! Once you’ve removed the ignition coils, you can carefully pull out the old spark plugs. Inspect them for wear and damage before installing the new ones.

Don’t forget to gap the new spark plugs according to the manufacturer’s specifications before installation. It’s essential for optimal performance! Also, be gentle with the threading—cross-threading can damage the engine.

Absolutely! That makes a big difference. Also, make sure to torque them to the right specifications for the best results. It’s a small detail that can cause problems later if overlooked.

It’s a good idea to wear gloves and safety glasses during this process. You never know when something might spring or fall when working under the hood!

Exactly, safety first! Also, take your time—there’s no need to rush. Double-check all connections and tools before starting the engine again after you’ve finished.

Does anyone have tips on which spark plug brands to use? I’ve heard mixed things about different brands, and I want to make an informed choice.

In my experience, AC Delco plugs work best for the Chevy Silverado. They typically offer good longevity and performance. Avoid the cheaper generic brands to prevent future issues.

This sounds like a fun project! I’m not a car expert, but with this tutorial, I might just give it a shot. What’s the worst that could happen, right?
