2008 Chevrolet Colorado Spark Plug Parts and Q&A

• Q: How to replace spark plugs safely and effectively on 2008 Chevrolet Colorado?

  A: One must remove ignition coils before starting the Spark Plug replacement process. Wear safety glasses for your eyes when operating compressed air since dirt particles may fly toward your face. Prepare the Spark Plug recess by cleaning it properly before removal to stop foreign debris from entering the Cylinder Head while performing these steps use a thread chaser to remove any contaminating substances from inside the threads. Before you remove spark plugs from a cooling engine it is crucial to clean the recesses with low-pressure air to prevent the threads from seizing. Any inspection of spark plugs must occur after plug removal. For engine safety use only the spark plugs recommended by the manufacturer because using different heat-levels of plugs may cause major engine damage. A round feeler gauge should be used to check the gap of all new and reconditioned spark plugs prior to installation because pre-set gaps might alter during handling and improper gaps could lead to both diminished engine performance and equipment damage. Compare the measured Spark Plug gap to its specifications and adjust it when needed. A thread chaser should be used to install the spark plugs because it helps avoid overheating while preventing exhaust blow-by and thread damage. The Cylinder Head requires the plug to fit smoothly and be completely seated. Put the spark plugs into the Cylinder Head and fasten them at 18 n.m (13 lb ft) before installing the ignition coils.
