Coolant Temp Senor and Knock Sensor

[towmater]

Smog guy is telling me I need to change these and I got them from the dealer. Just wanted to double check and see if anyone can confirm the locations of these on a bone stock 88' K5.

coolant temp for the computer should be in the intake manifold near the water neck. (coolant temp for the gauge should be in the drivers head) And the knock sensor is either in the passenger side head or on the side of the block, I cant recall exactly on the small blocks, but Im pretty sure its in the block on the pass side.

ok. I know where the knock sensor is now, just got to pin point the coolant temp sensor.

They are both easy to swap out correct?

yeh easy to swap, just be prepared to get wet when you take out the knock sensor, and dont break the plug, IIRC you have to squeeze in the sides to get it off as the knock sensor has a....mushroom style head on it.
