I recently took my 1996 Tahoe in for a check up and got a call that it was leaking coolant everywhere. I had recently replaced the water pump so I knew that was not the problem. After inspecting with a mirror, we saw that coolant was pouring out of the bottom of a sensor? on the back of the engine that leads to the intake manifold. I looked in my Haynes repair manual and can not find out what this sensor is. Please help if you have any ideas. I am all out of guesses?

Welcome to the forum. Well, I'd call the dealer and find out what it is. The Haynes manual may have just missed on this one. I have a hiltons and it is usually more complete.
