How to replace Knock Sensor (KS) 1 on 2004 Chevrolet Impala?

To replace Knock Sensor (KS) 1, one can start by lifting and supporting the vehicle. Drain the cooling system to avoid burnt injuries due to hot engine coolant, which might remain in the engine water jacket. Pull off the knock sensor electrical connector and take off the knock sensor . When the new knock sensor is installed, refrain from using thread sealant because the factory coating does an adequate job of functioning; ensure the tightening of the sensor up to 19 N.m (14 lb ft). Connect the knock sensor electrical connector, reduce the vehicle, and fill the cooling system.
