Hey there. Today I was driving home from work, when the 'Low Coolant' warning came on. I thought to myself, 'There'* no way.', because I had just checked the fluids the previous day after I washed her, and everything was kosher. I waited for the engine to cool-down, and just checked it again. Sure enough, the warning came-up again. So, I did what most people would do; Actually check the coolant. Again, the coolant level was fine. I have a feeling it'* the sensor, but I was wondering if it'* worth replacing, and how hard it would be for a newbie to do. Is this sensor something I could order? Thanks for any help.

Chances are it probably is the sensor. Over time the sensor builds up corrosion and scales on it in the radiator and can't "feel" coolant anymore and kicks on.

Odds are pull it out, clean it off, and put it back in and you should be fine..if u can't get it cleaned up enough, just replace it...Maybe a $20 part.

Thanks for the quick response. I'll probably do that. Do I have to drain the coolant before doing so?

You don't have to if you can find something to plug the hole while the sensor is out.....

I've never had to do it with my car.....Chances are you'd prolly be better off draining or pluging.

Or unplug the sensor if youi trust yourself to watch your fluids.

The light would still be on then wouldn't it?
