If you're really worried about it overheating, just put a mechanical temp gauge on it, to see exactly what it's doing.

What are your readings with the temp gun?

For temporary relief, just unplug the wire from the sensor.  All it does is complete the ground circuit when the set temperature is reached.

Drove the car for the first time. The mechanic replaced the sensor under the compressor but as I predicted the Engine Temp Light still came on. After using the temp gun all over the engine it was all under 200 degrees so clearly the engine isn't overheating. Going to replace the sensor at the back drivers side of the engine and hopefully wont have to listen to the buzz as I drive anymore. Also going to install a temp gauge into the port under the distributor cap too.

Thank you all for all the help

Thanks for the update.

A quick word of advice, keep all your old parts.

Does your heater blower come up to full speed if you set the dial to 85 and auto/hi ?   If not maybe the sensor behind the alternator is the metal temp alarm one and the one on the left is supposed to be behind the alternator.
