My low coolant light comes on after it warms up (95 T-A)
I am not loosing water, and the coolant is not low, no water in oil,
no oil in water, Bad sensor maybe????

 

having same problem

 

ditto that makes 3 of us, it goes on and off is why I dont think its the sensor so any advice is welcome.

 

I had the same problem for a while. Then I wiggled the connector on the coolant level sensor and I have had no more problems. People have also replaced the coolant level sensor for this issue, so search around and I'm sure you will find more suggestions.

 

It's a common problem. Lots of people just disconnect the sensor. Just remember to check coolant level every few days.

 

Sometimes a small bubble will get attached to the sensor, so it will mis-read. Happens a lot in the older GMs. Usually when this happens, I rap on the radiator tank a little with a screwdriver handle and that gets it loose. This cause would show up right after a coolant flush, or a wp replacement. Anytime you drain the rad and burp the system.

I had the same trouble with the low coolant light. It ended up being a head gasket.

 

i just unplugged my sensor, no problems

 

I unplugged my sensor too, no more problems! Just check your coolant levels from time to time.

 

I now have the same probem on a 93Z. When I contacted the dealer for a new sensor they informed me that it had been dicontinued in 02.Where do I go to get a new sensor? thanks

 

You could try removing the sensor and cleaning it. Sometimes a bit of buildup gets on the sensor and could cause it to malfunction.

 

I must be one lucky duck, cause I have never had this problem on mine, and I'm at 114K miles.

 

I had the same problem on my 97 TA went to autozone and special ordered a new sensor which cost me 70 bucks. drove it home turned the car off came back out to leave and it wasnt on and has never came back on so who knows. Now i have a brand new sensor that i have no use for.
