2007 Chevrolet Colorado Parts Questions & Experts Answers

• Q: How to replace spark plugs safely and effectively on 2007 Chevrolet Colorado?

  A: The first step to install new spark plugs requires ignition coils removal with protective safety glasses to avoid flying dirt. First clean the Spark Plug receptacle space to stop dirt and outside objects from accessing the Cylinder Head because this could damage the engine while simultaneously contaminating Cylinder Head threads possibly leading to improper new plug installment; employ thread cleaning tools as needed. You should clean the Spark Plug recesses by passing low-pressure air until all the plugs become removable from the Cylinder Head for examination. The vehicle requires its designated spark plugs because using alternative temperatures of plugs may result in fatal engine harm. A round feeler gauge should be used to check the gap accuracy of all new and reconditioned spark plugs because handling can affect their pre-set gaps; wrong gaps cause both performance degradation and engine damage. Verify the Spark Plug gap and thread it into the Cylinder Head while checking its full seating position. A thread chaser will keep you from damaging threads during installation if needed. The spark plugs should be installed into the Cylinder Head before tightening them to 18 n.m (13 lb ft). Afterward install the ignition coils.
