whenever i turn on my car, the coolant light warning comes on and constantly beeps. every like 3 times i drive it, it doesnt come on, but the other times it does. i checked my coolant level and it is at full. everything seems to be fine, so i thought it could be the sensor. yes?

 

If the coolant level is full, I would guess that it is the sensor. Replace it and see what happens

 

yeah im going to try that..its just very annoying because its my DD so i have to hear it all day long
