coolant light staying on after top up
hello if the level in the expansion tank is up to the mark and the engine isn't overheating then the level switch in the tank must be sticking / faulty so I'd suggest to unscrew the sensor from the side of the tank and clean it , also check the wiring for any damage and the connector for corrosion
