Last step before buying S5 GTU... coolant buzzer
Ok, went for a ride in the 89 GTU im VERY close to buying... but when we stopped at a gas station, the coolant buzzer when off, and the light came on near the clock.... I immediately said UH OH!!!!
I got out, looked at the tail pipe and was HOPING not to smell sweet smelling smoke. No smoke... ok good... He opened the radiator and coolant bottle... no bubbles... ok, good. (cant remember which one will make bubbles. So he opened the radiator, and started to pour a SMALL amount in... it immediately started to over fill. He said its only like the 2nd time its done it, but he pours some in just to be on teh safe side. Well, it was full....
Does this mean a bad sensor or am I dredding something else?
Thanks,
Jon

...94% correct.
Coolent level sensor can go off for a variety of reasons. My 87 sensor would react whenever the car got too hot, the level got low, the resavoir was empty, etc, etc. Did you start the car while it was cold? Were you present through the warm-up process? If I were you I would have a block test done, and have a mechanic look things over.

He put a LITTLE bit in there.. with the car running, and it would "surge" out.. (meaning it was full)

Im sure its just a bad sensor... god I hope so. I mean, no bubbles, no smoke, no smell of smoke (coolant smell)...

When it's cold(hasn't ran in a while) open up the system and check the level. Fill it up and try driving then.
Also check the overflow/resevoir tank. If it is almost to the VERY top(should only be 1/4 to 1/3 normally) then it might have a bad radiator cap and it is sucking air intop the system causing the light to go off.

There might be air in the coolant system.

Filling it cold is a good idea, first thing Im going to do when I get it

If the sensor has gotten a lot of gunk around it, it will do the same thing.
Easiest way to be sure is to remove the sensor, and test it using a multimeter by submerging it in coolant and seeing if it reacts. If it doesn't react properly, then you have found your problem.
In most cases, these issues disappear with a simple coolant flush to take all of the crap off of the coolant sensor.
