2010 Chevrolet Colorado Spark Plug Parts and Q&A

• Q: How to replace spark plugs safely and effectively on 2010 Chevrolet Colorado?

  A: Replace the spark plugs by first eliminating ignition coils from the engine. Wear protective glasses because compressed air operation may result in flying dirt particles causing eye damage. The Spark Plug recess area should undergo cleaning before removal to prevent foreign material from entering the Cylinder Head because such debris would harm the engine or contaminate the cylinder threads which might lead to improper new plug fitting; utilize a thread chaser to clean thread contamination. Low-pressure air cleaning should be used to prep Spark Plug recesses before waiting for complete engine cooling to reduce the risks of damaging Cylinder Head threads through plug thread seizing. Examine the removed spark plugs when the inspection ends. The engine needs its exact recommended spark plugs because alternative plug temperatures either hot or cold will cause serious engine damage. Use a round feeler gauge to measure sparkling gaps on new and reconditioned spark plugs before using them because the initial installation might change preinstalled gaps which can cause engine malfunction and destruction. Compare the Spark Plug gap to its specified value while making any necessary corrections. A thread chaser should be used for cleaning the threads during installation while checking that each Spark Plug threads properly before achieving full seat position. Fitting the spark plugs into each Cylinder Head requires a 18 nm (13 lb ft) of torque application. Finally, install the ignition coils.
