Revolutionize Your Ride: How to Change Spark Plugs 2017 Silverado for Optimal Performance

Are you experiencing rough idling, decreased fuel efficiency, or a lack of power in your 2017 Silverado? These could be signs that your spark plugs need replacing. While it may seem daunting, changing spark plugs on your 2017 Silverado is a relatively straightforward DIY project that can save you a significant amount of money compared to taking it to a mechanic. This comprehensive guide will walk you through the entire process, step-by-step, ensuring you have a smooth and successful experience.

Gathering Your Tools and Supplies

Before diving into the task, you’ll need to gather the necessary tools and supplies. Here’s what you’ll need:

• New spark plugs: Make sure you purchase the correct spark plugs for your 2017 Silverado. Consult your owner’s manual or a reliable online parts resource for the specific type and gap required.
• Spark plug socket: This specialized socket is essential for removing and installing the spark plugs. It’s typically a 5/8-inch socket with a rubber insert to prevent damaging the spark plug.
• Torque wrench: A torque wrench is crucial for tightening the spark plugs to the correct specification. Over-tightening can damage the threads, while under-tightening can lead to a loose connection.
• Ratchet: A ratchet with an extension bar will make it easier to reach the spark plugs.
• Wrench set: A set of wrenches will be helpful for loosening and tightening various components, such as the air intake manifold and coil packs.
• Gloves: Wearing gloves will protect your hands from grease and dirt.
• Safety glasses: Protect your eyes from potential debris.
• Shop towels: Keep your workspace clean and absorb any spills.

Preparing Your Silverado

Before starting the job, you’ll need to prepare your Silverado for the task. This involves:

• Park the vehicle on a level surface: This will ensure the engine is level and make it easier to work on.
• Engage the parking brake: This will prevent the vehicle from rolling.
• Disconnect the negative battery terminal: This will prevent any electrical shock and ensure safety.

Locating the Spark Plugs

The spark plugs on a 2017 Silverado are located on the top of the engine, under the air intake manifold. To access them, you’ll need to remove several components:

• Remove the air intake hose: This hose connects to the air intake manifold and needs to be removed to access the spark plugs.
• Remove the air intake manifold: The air intake manifold is held in place by several bolts. Use your wrench set to loosen and remove these bolts.
• Remove the coil packs: The coil packs sit on top of the spark plugs and need to be removed before you can access the plugs themselves.

Removing the Old Spark Plugs

Once you’ve accessed the spark plugs, you can begin removing them:

• Use the spark plug socket: Place the spark plug socket over the spark plug and use your ratchet to loosen it.
• Remove the spark plug: Once the spark plug is loosened, you can remove it by hand.
• Inspect the old spark plug: Before installing the new spark plug, inspect the old one for signs of wear or damage. This will give you an idea of the condition of your engine and help you determine if any other maintenance is needed.

Installing the New Spark Plugs

With the old spark plugs removed, you can now install the new ones:

• Apply anti-seize compound: Apply a small amount of anti-seize compound to the threads of the new spark plug. This will prevent the plug from seizing in the cylinder head.
• Install the new spark plug: Carefully thread the new spark plug into the cylinder head.
• Tighten the spark plug: Use your torque wrench to tighten the spark plug to the specified torque. This is typically around 15-20 ft-lbs.
• Repeat for each spark plug: Repeat the process for each of the remaining spark plugs.

Reassembling Your Silverado

Once all the new spark plugs are installed, you can begin reassembling your Silverado:

• Reinstall the coil packs: Carefully place the coil packs back onto the spark plugs.
• Reinstall the air intake manifold: Tighten the bolts that hold the air intake manifold in place.
• Reinstall the air intake hose: Connect the air intake hose back to the air intake manifold.
• Connect the battery terminal: Connect the negative battery terminal back to the battery.

Starting Your Silverado

With everything reassembled, you can now start your Silverado and check for any issues:

• Start the engine: Turn the key and start the engine.
• Listen for any unusual noises: The engine should run smoothly without any unusual noises.
• Check for any leaks: Check for any leaks around the spark plugs or air intake manifold.

Questions We Hear a Lot

Q: How often should I change the spark plugs on my 2017 Silverado?

A: According to the manufacturer’s recommendations, you should change the spark plugs on your 2017 Silverado every 100,000 miles or 5 years, whichever comes first. However, if you notice any signs of trouble, such as rough idling, decreased fuel efficiency, or a lack of power, it’s a good idea to have them inspected sooner.

Q: What type of spark plugs should I use for my 2017 Silverado?

A: The specific type of spark plug required for your 2017 Silverado will depend on the engine configuration. Consult your owner’s manual or a reliable online parts resource for the correct type and gap.
