How to replace the Knock Sensor (KS) on 2005 Chevrolet Equinox?

Start by elevating the vehicle before removing the knock sensor (KS). You need to detach the knock sensor (KS) electrical connector before removing the securing bolt and the KS device. Installation should avoid using thread lockers on sensor threads because factory coatings exist and extra thread lockers might interfere with detonation detection ability. Attach the KS to its designated spot on the engine block while tightening the KS bolt to 25 N.m (18 lb ft). Lower the vehicle while finishing by reconnecting the KS electrical connector.
