2006 Chevrolet HHR Question: Temp sensor location

I am getting intermittent failure of the temperature to read and check engine light comes on. previous repair string indicated bad temp sensor. I need to know location on engine - i found two sensors on the top but not sure which one is correct. 2.4 L engine -

My very best advice for instructions on this repair is to pay for a repair manual. You'll need the step-by-step and the diagrams. You can get even temporary access for a good price here: http://bit.ly/mitchell_repair_manuals_online -

does this need cleaned? The a/c does not work if the coolant temp gauge is not working.
this first happened several thousand miles ago, then suddenly started working properly. now again the guage does not read, the "check engine" indicatoe is lit, and the AC does not work.
