COOLANT LIGHT

2002 BMW 320i • 91,000 miles

My coolant light comes on and my heater does not work. My car runs out of oil alot quicker now. What could be the problem?

Check the coolant for the presence of oil and the oil for the presence of coolant.

Grasp the heater hoses just inside the engine compartment next to the bulkhead with the engine running and at operating temp. They should be hot. Move the temperature control back and forth and see if the heater control valve (if equipped) and/or blend doors move.

Is the outside of the engine covered in oil? If so, you need to clean it and then use a leak detector dye kit to locate the leak source. If it's an external leak.

Yeah the car is leaking oil from the bottom so we can't find out where it's coming from.
