Under the intake manifold. Make sure you get the harness for the knock sensors. and clean out all of the rust and junk you're going to find donw in the holes before and after you replace the sensors.
on the 4.3l version the knock sensor is on the back left side of the engine right by the bell housing. on the bigger engines they are below the intake manifold in the engine valley
The knock sensors are located in the rocker valley underneath the intake manifold. GEt a hynes manual to assist you in replacing them. There is acertain tightening sequence when taking the manifold on and off. It is made of a composite plastic so use care and do not over tighten.
