2007 Chevrolet Aveo Parts Questions & Experts Answers

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

  A: The first step for Spark Plug replacement should be checking that the engine is cool enough to avoid thread damage to the Cylinder Head. Cleaning the Spark Plug recess enables prevention of debris entry that causes engine breakdowns and improper new plug installation. The engine suffers serious damage if you install the wrong spark plugs which were not intended for the particular vehicle model. First step requires turning off the ignition followed by unbolt the 4 bolts and engine cover removal. The first step requires disconnecting Spark Plug Wires before pulling out spark plugs from the engine position. A round wire feeler gauge should be used for Spark Plug gap inspections on new and reconditioned units because handling results in pre-set gap alterations. Before installation gap the spark plugs according to specifications to achieve full thread engagement with the Cylinder Head. Known as a thread chaser you can use this tool to clean the threads if needed. The recommended torque values must be followed exactly to prevent Spark Plug thread damage and overheating by tightening them to 25 n.m (18 lb ft). Install the engine cover while reattaching the Spark Plug Wires and secure the 4 bolts with a torque of 3 n.m (31 lb in).
