just so Q. the display on the dash show low coolant. i know i have enough coolant, is this the senser that plugs into the radiator? if not wear? is there a way i can just cross some wires so that the warning doesn't come on? how much is this part?

Yes, the sensor is in the radiator and it probably needs to be taken out and cleaned.

Be careful putting it back in because the O-rings (2) are delicate and rip easy (experience!!). To replace it cost me 30 bucks or so. To bypass it, a paper clip between the connector taped up does it but that is just butchering a beautiful car!!!

the problem is that i can't seem to find the sensor locally. the warming light doesn't come on all the time, it would come on and go out or just stay on for a while. i just want to stop this for the mean time because the ringing sound and light is making me nuts, especially when it goes off when i have someone else in the car, i just want to patch it up till i can get a sensor.
i took a look at the plug but there are three wires in it, so witch one on the wires do i have the connect together.

Right, I think the newer ones are integrated with a module that also senses oil levels in the engine. I'm not quite sure how to jumper it.

ABC... I'm having the same problem in my 91.... you think your might be able to help me clean/replace my sensor?

You think the dinging is bad when you show low coolant, you should see what happens when your instrument cluster is messed up. Mine would ding dong, flash,buzz, go dark, etc randomly and without warning. And usually when I was trying to show someone how nice my car was !!!!!
