2004 Buick Park Avenue Parts Questions & Experts Answers

• Q: How to replace spark plugs on 2004 Buick Park Avenue?

  A: Starting the replacement process requires turning off the Ignition Switch first then removing the fuel injector sight shield. Take note of Spark Plug wire positions before unfastening them then turn Spark Plug boots one half turn counterclockwise before disconnecting. The Spark Plug boot removal tool (J 38491) enables the user to gently lift the heat shield away from the spark plugs during the operation. Use the appropriate tool to pull out the spark plugs that are within the engine compartment. Check the Spark Plug gap prior to installation but modify it when needed based on manufacturer specifications. The specification for installing new or used spark plugs into a used Cylinder Head with normal engine thermal cycle requires 15 n.m (11 lb ft) reinstallation torque. To install spark plugs within a new Cylinder Head without engine thermal exposure apply the starting installation torque of 27 n.m (20 lb ft). Install the fuel injector sight shield and join Spark Plug Wires to their plugs.
