2002 Buick Park Avenue Parts Questions & Experts Answers

• Q: How to replace the Knock Sensor (KS) 2 on 2002 Buick Park Avenue?

  A: The first step is to turn the ignition off and lift the vehicle for sensor replacement. Begin by extracting splash shield bolts then empty the cooling system of fluid. The two bolts securing the Knock Sensor heat shield below the freeze plug need removal. Start by disconnecting the wiring harness connector from the Knock Sensor and afterward unfasten the Knock Sensor from its position on the engine block. The sensor threads come factory-coated so applying thread sealant would compromise proper detonation detection and should be omitted when performing installation. Tighten the Knock Sensor into position at 19 n.m (14 lb ft). Begin by securing the Knock Sensor heat shield through bolting it at 60 n.m (44 lb ft). After connecting the Knock Sensor to its electrical connector, reinstall the splash shield followed by lowering the vehicle and refilling the cooling system.
