2003 Buick Park Avenue Parts Questions & Experts Answers

• Q: How to replace the Knock Sensor (KS) 2 on 2003 Buick Park Avenue?

  A: Start by turning off the Ignition Switch before lifting your vehicle up for the replacement of the Knock Sensor (KS) 2. Start by taking out splash shield bolts while you empty the cooling system. Next remove the two bolts from the Knock Sensor heat shield installed beneath the freeze plug or block heater component. A disconnect of the wiring harness connector follows the removal of the Knock Sensor from the engine block. The sensor's factory coating requires no thread sealant during installation because this factory coating serves as the foundation for proper detonation detection. Screw the Knock Sensor into the engine block until it reaches a torque of 19 n.m (14 lb ft). Secure the Knock Sensor heat shield with 60 n.m (44 lb ft) torque before reinstalling. At the end of the installation process, finish by connecting the electrical connector to the Knock Sensor before putting on the splash shield and lowering the vehicle for a cooling system refill.
