2004 Buick Park Avenue Parts Questions & Experts Answers

• Q: How to replace the Knock Sensor (KS) 2 on 2004 Buick Park Avenue?

  A: Replace the Knock Sensor (KS) 2 by first switching off the ignition and then lifting the vehicle. Start by draining the cooling system while removing splash shield bolts. Start by unfastening both Knock Sensor heat shield retaining bolts beneath the freeze plug or block heater. Detach the wiring harness connector from the Knock Sensor position before removing the sensor from the engine block. The new Knock Sensor requires no thread sealant because its factory coating is crucial for detonation detection. Set the new Knock Sensor inside the engine block at 19 n.m (14 lb ft) torque. After putting back the Knock Sensor heat shield, use 60 n.m (44 lb ft) torque when tightening the bolts. After connecting the electrical connector to the Knock Sensor users should reattach the splash shield while lowering the vehicle until they complete the cooling system replenishment.
