Here's the story.

Last week I was at work and parked on a hill. It wasn't real steep, but steep enough. Well, when I came out of work and started the car, the coolant light reared its ugly head.

I immediately drove home, let the car cool, and checked the coolant. The coolant was full. There were no particles in it, and it was not low. The overflow also indicated that the car wasn't low on coolant.

For the past week, I've been trying to get the coolant situation straightened out. I went so far as to flush the radiator, and "start over." No dice.

I've tried running the car, then shutting it off, as the owners manual instructed, only to continue to add coolant until the radiator was full. Now the overflow is "overflowing." I've obviously got too much coolant in it!

I've replaced the thermostat, flushed the radiator, made sure the radiator cap was tight, put the car up on stands to make sure the waterpump wasn't leaking, the head gaskets weren't leaking, the radiator wasn't leaking, made sure no hoses were loose or leaking, etc.

Guys, I'm stumped. What else can I do? Could it be a malfunctioning dummy light? Is there some type of sensor that may need replacing? I'm totally clueless as to what the problem is, and I've been chasing it for a week.

Also, sometimes I can drive the car for about 15-20 minutes with no problems, and THEN all of a sudden the coolant light will come on. The car is not overheating, and the temperature gauge is running within normal operating temperature. I'm not smelling antifreeze or anything.

HELP ME!

change or clean the sensor on the side of the radiator, that seems to be the biggest problem with the coolant light, you might just unplug it first off and see if the light still comes on.

Ummm, what's the sensor look like, and approximately where is it located? Also, would I need to drain out any coolant?

I've had that damn light come on and off again for the past month or so. But, I knew it was a bogus sensor. I'm pretty much ignoring it. Do a search on this and uses Shoebox's advice.

just take that sensor out and check your coolant every once in a while. asked the same thing a few months ago and now no light and no prob.

I checked the link that someone offered up, and it looked like the sensor was some type of "box." I went to Pep Boys (Dope Boys) and picked up a temperature sensor, and it looks like a bolt. It came with a connector and these little "splice" things. I haven't bothered taking the car apart yet, as it's pretty hot out right now. I'm waiting until later tonight. Did I get the right part?

Its not a temperature sensor, its a fluid level sensor. Try removing your old one and cleaning it up really well. The bolt looking thing you got isnt the right part.

Coolant Level Sensor is what you need, not a temperature sensor. What you bought probably screws in to the driver's side cylinder head.

Coolant level sensor.

Thanks for the info, guys. I replaced the coolant fluid sensor last week, and that has resolved the problem. A simple 5 minute job.
