Take off the cable from the battery's negative terminal. The 4.3L V6 engine knock sensor is located on the back part of the engine block, to the left of the distributor. A threaded unit is screwed into a block for the knock sensor found in 1996 through 2000 models. On 2001 and later models, however, there is a knock sensor yet it is located at this point but bolted to a block. Eliminate an engine cover.Disconnect an electric contactor from a knocking sensor. Removing the shock absorber from the socket.Eliminate an electric socket by carefully screwing out its plug.Remove it with simply unscrewing it.Such are on 2018 and beyond versions of 4.3L V6 engines that have two detonation sensors positioned under each distal part of exhaust.Central bolt can be removed to take away those detectors out.First you should remove fasteners or nuts while turning them counterclockwise.Installation basically involves following removal procedures.Be carful when fixing torque either for tightening knock sensor or mounting bolt, otherwise, tightening will result in bad outcomes.For all these three engines (5.0L, 5.7L and 7.4L), their right side before starting motor has got one device meant for detecting early emissions of abnormal sounds.Prior to any checks after repair work, lift car front so as to put jacks below front wheels.Turn off an electrical connector through which a knocking sensor communicates.Untwist and get rid of a shock absorber.It comes down to reversing disassembling procedure in order to install it.The only thing needed now is tightness of this component.Either way it should be done correctly only once fitted instead.In such situations never employ any sealing substance plus thread resistant material onto knocking detector or its attaching means.This kind of adjustment causes poor work rate either by tightening more than that or lesser than the needed level of a knocking sensor.
