I can't find the engine coolant temperature sensor. Could somebody please provide super detailed directions to it? I have googled every combination of words I can think of, with nothing particularly helpful coming up. I know very little about cars and am learning out of necessity, so I may have follow up questions.

Hi,

It is at the rear of the engine cylinder head (close to where the transmission/engine are bolted together) below the intake manifold. If you look under the intake, there is a bracket that attaches it to the cylinder head. The sensor is to the left of the very bottom of that bracket.

I tried to find a clear picture but with no luck. I attached the best I could find. I also attached the directions from the manual for replacing it.

Let me know if this helps. Also, certainly, let me know if you have questions or if I can help in any way.

Take care,

Joe
