2005 Buick Park Avenue Parts Questions & Experts Answers

• Q: How to replace spark plugs in an engine on 2005 Buick Park Avenue?

  A: The replacement of spark plugs requires users to begin by turning off the Ignition Switch followed by removing the fuel injector sight shield. Start by noting wire positions before removing them and apply a 1/2 turn twist to the Spark Plug boot prior to removal. The Spark Plug boot removal tool (J 38491) allows gentle lifting of the heat shield before removing the Spark Plug Wires from their sockets. The next step involves taking out engine spark plugs. The correct process for new Spark Plug installation requires measuring their gap and matching it against specifications while adjusting as needed between steps. The engine spark plugs need installation with a torque setting of 15 n.m (11 lb ft) specifically for new and used spark plugs being fitted to a used Cylinder Head which completed a normal engine thermal cycle. New cylinder heads requiring Spark Plug installment must receive their torque set at 27 n.m (20 lb ft) according to the initial specification. Add the Spark Plug Wires to their respective spark plugs before finally replacing the fuel injector sight shield.
