2008 Chevrolet Equinox Spark Plug Parts and Q&A

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

  A: Engine replacement of spark plugs requires an initial wait for engine cooling until threads on the Cylinder Head are safe. The Spark Plug recess area requires cleaning to stop dirt from entering the Cylinder Head because such contamination blocks proper seating of new spark plugs. It is essential to use only the spark plugs which are originally designated for the vehicle model since alternative temperature levels of plugs will seriously destroy the engine system. Detach the Spark Plug Wires before removing spark plugs from their installation position within the Cylinder Head. A round wire feeler gauge should be used to verify the gap of new and reconditioned spark plugs before installation because their pre-set gaps might have altered. Proceed with gapping new spark plugs by referring to the ignition system specifications. The plug needs to slide smoothly through the Cylinder Head while reaching full insertion depth by using a thread chaser on soiled threads. Pay close attention to the torque specifications because improper tightening may result in overheating as well as exhaust blow-by and thread damage. Beginner installments of spark plugs into new cylinder heads should reach 20 n.m (15 lb ft) torque but subsequent installations need only reach 15 n.m (11 lb ft). The final installation step involves placing the spark plugs inside the Cylinder Head after tightening them to 15 n.m (11 lb ft) and completing wire reconnection.
