1992 Mercedes-Benz 300E Q&A

1992 Mercedes-Benz 300E Question: engine coolant light always on, normal running temp on gauge and fluids ok

Is it a faulty sensor? -
Answer 1
Probably the coolant level sensor. Located in the expansion tank. A new sensor is around $30.00 and not too hard to change. If you simply unplug the sensor the light should go out. Otherwise there may be a short to ground further up the wire harness. -

it can be the sensor in your cooling tank that is not reading right. -
