Low Coolant light Hey guys, I'm pretty new at this, but I'm slowly learning and replacing parts as I go along. Frankly, dealerships and shops are too freakin' expensive, and I'd like to do the work myself and say that I did it. But here's what I have going on. I drive a 1993 Firebird Formula, thermostat rated 185 because of the engine type. Anyway, the low coolant light comes on and off periodically, and I can't get it to go off. I think I need to replace the sensor in the radiator (already replaced the thermostat and thermostat sensor in the housing but that didn't fix it because it heated to about 230 and I was kinda worried that was a little too hot). I'm just having trouble finding the sensor (supposedly on the backside of the radiator). It's a little mess in there, and I was wondering if anyone could tell me where abouts to start looking. It would be much appreciated.
Fixing a Formula, so it's in decent working condition, until I can put it up and completely tear it apart as a project car

yeah, same here. I just replaced a leaky heater hose, so I know I'm fine on coolant. I'm trying to locate, but won't get to it until monday when I have some time.

there should be a sensor with a wiring harness on it, on the back side of the radiator. When I find it, I'll let you know, so maybe that would be your problem as well.

low coolant sensor The sensor is under the upper radiator hose. Just unplug it, light will go out.I did this on my 96 formula and never had an issue. Just make sure you keep it full.

Actually, all you have to do is pull the sensor out of the rad and use some light sandpaper and sand the probe until it is shiny again. They get gummed up over time and throws the sensor off. Just make sure you drain a little coolant first or you'll have a mess.

Me and a friend were working on my car and he noticed my coolant sensor was unplugged. Its a dummy sensor that gets messed up and won't go away unless you fit it. Just unplug it and keep track of your coolant level.
