2007 Chevrolet Equinox Spark Plug Parts and Q&A

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

  A: Engine replacement starts with waiting for engine cooling to stop because sealing problems may occur when handling Cylinder Head threads. Thoroughly clean the Spark Plug recess space to stop debris from entering the Cylinder Head because this material can make the threads become contaminated resulting in improper Spark Plug seating. The engine faces severe damage when using spark plugs outside of the specified vehicle model. Start the procedure by detaching Spark Plug Wires from their positions on the spark plugs before you remove these plugs from the Cylinder Head. A round wire feeler gauge should be used to check gaps on newly installed or reconditioned spark plugs before mounting them as pre-adjusted gaps might have changed. Follow the gap specifications mentioned in ignition system specifications when dealing with spark plugs. The plug threads should enter the Cylinder Head smoothly until it reaches full seat position; use a thread chaser to clean threads when needed. It is important to follow recommended torque limits precisely because improper screw placement might result in overheating and exhaust leaks and thread damage to the system. First-time installation of spark plugs in new cylinder heads should have a torque specification of 20 n.m (15 lb ft) while all subsequent installations follow a torque value of 15 n.m (11 lb ft). The process ends with attaching the Spark Plug Wires to their fitting points on the spark plugs.
