This guide will walk you through the process of changing spark plugs on your 2016 Jeep Cherokee, providing step-by-step instructions and helpful tips.

Gather Your Tools and Supplies

Before you begin, make sure you have all the necessary tools and supplies on hand. Here’s what you’ll need:

• New spark plugs: Consult your owner’s manual for the correct spark plug type for your 2016 Jeep Cherokee.
• Spark plug socket: This special socket is required to remove and install the spark plugs.
• Torque wrench: This tool ensures that the spark plugs are tightened to the correct specifications.
• Ratchet and extension: You’ll need these to reach the spark plugs.
• Socket wrench: A standard socket wrench will be needed to remove the air intake manifold.
• Flathead screwdriver: This is used to disconnect the battery terminals.
• Gloves: Protecting your hands is always a good idea.
• Safety glasses: Protect your eyes from potential debris.
• Shop towels: Keep your work area clean.
• Optional: Anti-seize compound: This can help prevent the spark plugs from seizing in the cylinder head.

Disconnect the Battery

The first step is to disconnect the battery to prevent any electrical hazards.

1. Locate the battery: It’s typically located in the engine compartment.
2. Disconnect the negative terminal: Use the flathead screwdriver to loosen the nut securing the negative cable to the battery terminal.
3. Disconnect the positive terminal: Repeat the process for the positive terminal.

Remove the Air Intake Manifold

To access the spark plugs, you’ll need to remove the air intake manifold.

1. Locate the air intake manifold: It’s the large plastic or metal housing connected to the throttle body.
2. Disconnect the air intake hose: There will be a clamp securing the hose to the manifold.
3. Remove the air intake manifold bolts: These bolts are typically located around the perimeter of the manifold.
4. Remove the air intake manifold: Gently pull the manifold off the engine.

Remove the Spark Plugs

Now you’re ready to remove the old spark plugs.

1. Locate the spark plugs: They are typically located on the top of the engine, near the cylinder head.
2. Use the spark plug socket: Attach the spark plug socket to the ratchet and extension.
3. Remove the spark plugs: Slowly turn the socket counterclockwise to loosen and remove the spark plugs.
4. Inspect the old spark plugs: Check for any signs of wear, damage, or fouling.

Install the New Spark Plugs

Once the old spark plugs are removed, it’s time to install the new ones.

1. Apply anti-seize compound: If using, apply a thin layer of anti-seize compound to the threads of the new spark plugs.
2. Hand tighten the new spark plugs: Screw the new spark plugs into the cylinder head by hand until they are snug.
3. Use the torque wrench: Tighten the spark plugs to the specified torque setting found in your owner’s manual. Over-tightening can damage the spark plugs and cylinder head.

Reinstall the Air Intake Manifold

After installing the new spark plugs, reassemble the air intake manifold.

1. Align the air intake manifold: Ensure the manifold is properly seated on the engine.
2. Tighten the air intake manifold bolts: Tighten the bolts to the specified torque setting in your owner’s manual.
3. Reconnect the air intake hose: Secure the hose to the manifold using the clamp.

Reconnect the Battery

Finally, reconnect the battery.

1. Reconnect the positive terminal: Tighten the nut securing the positive cable to the battery terminal.
2. Reconnect the negative terminal: Tighten the nut securing the negative cable to the battery terminal.

Start the Engine and Check for Issues

Start the engine and let it run for a few minutes. Listen for any unusual noises or check for any warning lights on the dashboard. If everything seems fine, you’ve successfully changed your 2016 Jeep Cherokee’s spark plugs.
