Galaxie500XL Posted August 5, 2009 Report Share Posted August 5, 2009 I have replaced the radiator in my '95 Cutlass convertible 3.4 DOHC, and run into a problem. The coolant low sensor keeps lighting up after the radiator was replaced. I noticed that the sensor was leaking, so I purchased a new sensor, but the problem persists. The light will go out for a little while, then come back on...and the radiator is definitely full. Any suggestions on how to resolve this would be appreciated...

SrMichi Posted August 5, 2009 Report Share Posted August 5, 2009 i had the same thing happen on my previous car after i flushed and change the sensor. Does it come back on when you accelerate? And turn off when you’re braking? If that’s the case I believe your radiator is still low on coolant. Quote Link to comment Share on other sites More sharing options...
Galaxie500XL Posted August 5, 2009 Author Report Share Posted August 5, 2009 The radiator appears to be all the way to the top...but I'll check it again. Thanks! Quote Link to comment Share on other sites More sharing options...
GP4U2NV Posted August 5, 2009 Report Share Posted August 5, 2009 Could be ther wrong sensor that you installed. Also, could have a short in the wires. To prove if it is a sensor, disconnect the sensor and drive. It should not come on. If it comes on then it is the wiring. Quote Link to comment Share on other sites More sharing options...
Galaxie500XL Posted August 5, 2009 Author Report Share Posted August 5, 2009 I was debating disconnecting it to check, but was not sure how the circuit worked. I've bought the factory service manuals for the car (EBay, $38.00), but they're not here yet. Quote Link to comment Share on other sites More sharing options...
GP4U2NV Posted August 5, 2009 Report Share Posted August 5, 2009 Mine has been disconnected since the swap. All the time without coolant in the radiator caused it to fail. I check my oils and such often and I do watch my gauges. Quote Link to comment Share on other sites More sharing options...
dylan1630 Posted August 5, 2009 Report Share Posted August 5, 2009 Mine is messed up too, it comes on while i'm driving and then it starts flickering really fast but it's like $52 for a new one which is ridiculous, so i'm probably gonna just unplug mine and check it to make sure it's not low.

Galaxie500XL Posted August 6, 2009 Author Report Share Posted August 6, 2009 I believe I've resolved the problem. The design of the sensor is rather poor, and can allow an air bubble to be trapped in the sensor. When I went to church last night, I parked the car up on the hill with the right side of the car on the low side, which seems to have allowed a trapped air bubble to escape from the sensor. The light has stayed off ever since. Quote Link to comment Share on other sites More sharing options...
