\015 1990 Regal Coupe 3.1 engine. Radiator replaced and 2 low coolant switches tried, but the low coolant light in the dash remains on. Checked for hot lead...no power to switch. GM dealer could not help.\015 Posted / edited by AnonymousUser on : 26-10-2020

Answers :

This is a COMMON Problem that GM had with the Level Sensor Curciut, And they Never Correctly Addressed it. I Have on ocations Replaced the Sensor and that Corrected the Problem, BUT Other times the Light STAYS ON No matter What, I have tracked the Wires and all I Have Ever Found was the Plug Being FAULTY. So if A NEW Coolant LEVEL SENSOR Does NOT Turn off the Light, try Replacing the PLUG Itself.
