2000 Buick Regal Parts Questions & Experts Answers
Q: How to service and repair spark plugs on 2000 Buick Regal?
A: The servicing and repairing of spark plugs starts with turning off the Ignition Switch. The Spark Plug heat shield removal tool (J 38491) serves as a tool for removing the heat shields easily. First inspect the engine temperature until it gets cool before attempting plug removal to prevent thread damage of the cylinder heads by sticky threads. Before sparking plug insertion clean the recess area thoroughly to stop any foreign material or dirt entry that could stain the threads thus affecting proper seating abilities. A thread chaser serves this purpose. The removal of engine spark plugs requires selecting only the manufacturer-recommended plugs since different plug types can create lasting damage to the engine system. Local judgment of the Spark Plug gaps must be confirmed using a round feeler gauge before installation because the initial gaps might have altered through handling; refer to gm spo group numbers for specifications. The correct installation of the Spark Plug requires simple thread entry into the Cylinder Head followed by complete seating of the plug by using a thread chaser tool to prevent cross-threading problems that may cause overheating or exhaust blow-by or thread damage. After installing the new spark plugs into their positions tighten them to 15 n.m (11 lb ft) before reattaching the Spark Plug Wires.
