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

  A: To replace Knock Sensor 2 begin by turning off the Ignition Switch and then lifting the vehicle into position. Start by removing the splash shield bolts and draining the vehicle's cooling system. To start the replacement process remove the two bolts found under the freeze plug or block heater that secure the Knock Sensor heat shield. Unplug the wiring harness connector from the Knock Sensor before extracting the sensor from its position on the engine block. Installation of the sensor requires avoiding thread sealant on the threads because casting on the sensor threads ensures appropriate detonation detection. Screw the Knock Sensor into its position in the engine block with a torque of 19 n.m (14 lb ft). The Knock Sensor heat shield requires reinstallation followed by tight bolting at 60 n.m (44 lb ft). Lower the vehicle afterward while reinstalling the splash shield and hook up the electrical connections to the Knock Sensor. Complete the process by filling the cooling system then checking the fluid level.
