Low Coolant Warning Light Help
My daughter's '99 Mustang GT intermittently displays the low coolant warning light even though the radiator and coolant recovery tank are full. The car never registers any higher than the mid-point on the temperature gauge. Any ideas what might be the culprit? I'm not sure if a '99 has a coolant tank sensor. Thanks!

My '00 Contour does this also but there is a known cure. The sensors are a float type that activates a magnetic switch, add coolant to the overflow tank about 1/2 or more pass the max fill line keeps them happy for some reason. It was a problem for some Fords around this time frame. If this doesn't work then either check the plug or you have a bad sensor but this is a common way to fix this including myself have cured the light this way.
