Engine coolant sensor '96 a4 2.8
 

I've bought the part and cannot find its location. Can anyone point me to it? Every other post I've found says its a simple fix taking 5-10min.

The advise in the repair book I bought doesnt seem to point me in the right direction.

on the 12v its a real PITA, if you remove the engien cover, intake hose, loosen the intake plenum (black part not eh manifold) and move around some wires its take like a minute to replace. if you send a pic of your engine with the cover off i can give a you a general idea of where it is. when i did mine i wnet from teh bottom and snaked my hand around the exhaust to the coolant flange ont eh back of teh engine. also are you sure you got the blue top 4 pin square and not he updated green one.
