How to replace spark plugs safely and effectively on Chevrolet Colorado?

Safety glasses will protect the eyes during the Spark Plug changing process as you use low pressure air to clean the Ignition Coil recesses before removal. The prep step involves cleaning the Spark Plug recess area before removal because foreign materials could enter the Cylinder Head to cause engine harm while potentially damaging Cylinder Head threads and blocking new plug installation. The thread chaser tool removes any contamination that might be present on threads. Let the engine cool down before plug removal because thread seizure can harm Cylinder Head threads. Regular checks should be performed on spark plugs. Use a round feeler gage for accurate measurements to check new plugs' specified gaps then install them into the Cylinder Head while ensuring smooth thread engagement but also complete seating. Improper gaps lead to performance issues or engine damage. Place each Spark Plug into its respective Cylinder Head while assuring that threads belong together properly and each plug sits entirely within its opening. A thread chaser tool (Thread Chaser) helps clean Cylinder Head threads when cross-threading occurs since improper fixture may result in overheating alongside exhaust blow-by and thread strain. After installing the ignition coils reinstall them by tightening each Spark Plug to 18 n.m (13 lb ft).
