Low coolant alarm

[J_Rok]

If you can pull the sensor out of the reservoir and no coolant comes out odds are you have the magnet style sensor. With the sensor pulled out of the reservoir but wiring connected put a magnet near the sensor if the light goes out you need a new tank. If the light stays on you need a new sensor or have a wiring issue. If you have to start digging into the wiring I’d suggest getting a free quickserve account it’ll save you loads of time in finding the correct pins on the ecm harness.
