There is a sensor valve located inside the reservoir its may be bad
how to change third or center brake light on Chevy beretta 95
Check the coolant level and make sure that its full, and is not leaking down over time. If the system is full then the low coolant sensor is probably bad.
Brake light switch defective or out of adjustment.
There is a sensor either in the coolant recovery jug or the radiator side tank that is defective.
Make sure your coolant is FULL, it will stop reading if your coolant is low and the low coolant light doesn't always work. My radiator was full and i took the thermoustat off to find the block hlaf empty on my 91. Paco
I will assume that the radiator is full. there is a sensor that tells you when it's low. It should be close to the top of the radiator or coolant tank. if it isn't unplugged or the wires broke, then it's bad. They are easy to replace. just unscrew it and screw in another.
coolant sensor replacement need it
if coolant is ok!! then check coolant sensor.
the low coolant light is only for radiater coolant,does not have anything to do with fuel pump!!
My coolant light come on want can it be.
