My low coolant light turned on today and I went and got some 50/50 antifreeze and filled her all the way up. I drove the car around for a while and the light still won't turn off. Do I need to reset the computer or what else could be wrong?

 

If you filled up the reservoir, it might take a little while to get in to the radiator. The sensor is near the lower radiator hose.

 

Ok that's what I was thinking but I wasn't sure. Thanks for the help!

 

the coolant sensor is very prone to failure it gets corroded and stops working causing the light to stay on. Unplug the sensor and pull it out clean it with some sos pads or oven cleaner just make sure it is thoroughly flushed of all cleaners. That might make it work again just o you know you will loose a decent amount of coolant when you pull the sensor.
