2009 Chevrolet Colorado Spark Plug Parts and Q&A

• Q: How to replace spark plugs safely and effectively on 2009 Chevrolet Colorado?

  A: The first step in replacing spark plugs requires ignition coils removal. When using compressed air while working always wear safety glasses to protect your eyes from flying dirt particles. A thorough cleaning of the plug recess will help stop dirt from entering the Cylinder Head preventing both engine damage and thread contamination while assisting with new plug seating. A thread chaser will remove any thread contamination. Let the engine cool while using low-pressure air to clean Spark Plug recesses so the plug threads don't seize or damage the Cylinder Head threads. You should examine the spark plugs following their removal. Use spark plugs designed for your vehicle because differing designs might create serious engine harm. A round feeler gauge should be used to check the gap on new along with reconditioned spark plugs before installment because they often get altered during their handling period. The use of incorrect gap settings may result in engine deterioration and failure. Use a round feeler gauge to measure the Spark Plug gap then adjust it according to specifications. Check that the Spark Plug threads reward resistance when inserted into the Cylinder Head while maintaining full seat depth by utilizing thread chasers to clean dirt from threads. Secure the spark plugs within the Cylinder Head using a torque of 18 nm (13 lb ft) before completion. Finally, install the ignition coils.
