2006 Buick Lucerne Parts Questions & Experts Answers

• Q: How to replace the spark plugs in an engine on 2006 Buick Lucerne?

  A: Starting the Spark Plug replacement requires removing the intake manifold cover if required. Begin by writing down the Spark Plug wire positions then twist the plug boots half a turn counterclockwise before extraction and carefully elevate the plug heat shields with the Spark Plug boot removal tool (J 38491). Repeating the same steps is required to remove Spark Plug Wires found at the rear section of the engine. Use the specified tools to remove spark plugs that are situated in the engine compartment. Check the new spark plugs for their gap measurement before you install them by comparing with recommended specifications. Placing the spark plugs inside the engine requires a proper tightening of 15 n.m (11 lb ft). Close the process by attaching Spark Plug Wires to their respective spark plugs both at the rear and front engine positions before reattaching the intake manifold cover if you removed it.
