2015-2022 2nd Gen Chevy Colorado GMC Canyon Air Intake Manifold Removal for Spark Plug Ignition Coil

Introduction

This tutorial will guide you through the process of removing the air intake manifold and replacing the spark plugs and ignition coil packs on a 2015-2022 2nd Gen Chevy Colorado or GMC Canyon with a 3.6L V6 engine. This step-by-step guide is essential for accessing the bank 2 spark plugs and ignition coil packs, as well as other components like VVT solenoids and camshaft position sensors.

Step 1: Gather Tools and Materials

Before starting, make sure you have the following tools ready:

• Torque wrenches (foot-pound and inch-pound)
• 3/8-inch ratchet with extensions
• 1/4-inch ratchet
• T25 Torx bit and screwdriver
• 10mm, 13mm, and 14mm sockets (deep well recommended)
• 10mm open-end wrench
• AC Delco spark plugs (part number 41-130)

Step 2: Disconnect the Battery

1. Use a 10mm wrench to disconnect the negative battery terminal to prevent any electrical issues during the process.

Step 3: Remove the Air Intake Cover

1. Refer to a dedicated video or guide for detailed instructions on removing the air intake cover if needed.

Step 4: Remove the Throttle Body

1. Using a 10mm socket, remove the four bolts securing the throttle body.
2. Disconnect the electrical connector by:
   • Popping out the gray clip.
   • Pressing down on the black button and sliding the connector out.
3. Set the throttle body aside.

Step 5: Disconnect Additional Connectors

1. Remove the actuator solenoid clip using a T25 Torx bit.
2. Disconnect any additional clips and wires connected to the manifold.

Step 6: Remove the Intake Manifold

1. Unscrew the 10mm and 13mm bolts securing the intake manifold. Ensure you reach all necessary bolts, including those at the back.
2. Gently lift the intake manifold, ensuring no cables or wires are still attached. Be cautious of any vacuum lines.
3. Clean any debris from the intake ports.

Step 7: Access the Spark Plugs and Ignition Coils

1. With the intake manifold removed, locate the ignition coil packs and spark plugs.
2. Disconnect the ignition coil connectors by pushing the red tab and pulling the connector out.

Step 8: Replace Spark Plugs

1. Use a 14mm spark plug socket to remove the old spark plugs. Carefully loosen and pull them out.
2. Compare the old and new spark plugs. The new AC Delco plugs should be pre-gapped at 0.035.
3. Apply dielectric grease to the boot of the ignition coil pack.
4. Install the new spark plug by hand, followed by using a torque wrench to tighten it to 13 foot-pounds.
5. Reinstall the ignition coil pack and torque it to 8 inch-pounds.

Step 9: Reassemble Components

1. Reconnect all electrical connectors and ensure all clips are secure.
2. Place the intake manifold back onto the engine, ensuring all gaskets are properly seated.
3. Reattach the bolts to secure the intake manifold, torquing them to the manufacturer's specifications (18 foot-pounds).

Step 10: Reinstall Throttle Body

1. Position the throttle body back in place and secure it with the four 10mm bolts.
2. Torque the throttle body bolts to 89 inch-pounds.

Step 11: Final Checks and Reconnect Battery

1. Double-check that all connections, sensors, and clips are reattached properly.
2. Remove any rags or debris from the intake ports to prevent contamination.
3. Reconnect the negative battery terminal and tighten it down.

Conclusion

You have successfully removed the air intake manifold and replaced the spark plugs and ignition coil packs on your Chevy Colorado or GMC Canyon. This process not only improves engine performance but also allows for access to various components for future maintenance. Make sure to start your engine and check for any warning lights or unusual sounds before taking your vehicle back on the road.
