I have a 1997 bmw 318i that is overheating. Steam comes from back of engine compartment and the fan is not engaging. What could the problem be?


It is likely that the heater core has sprung a leak, or the hoses leading to the heater core have failed. This would cause a loss of coolant that would make the coolant temperature sensor think it wasn't necessary to turn the fan on, and would cause steam to appear to rise out of the back of the engine. If you turn the heater on inside the passenger compartment and get steam through the vents, it's DEFINITELY a heater core breach. Otherwise, check the hoses leading to the heater core and make sure they are still connected and not leaking. Good luck!

BMW 318iSE (1999) engine warning light


That sounds like you bought big problems. Oil ights indicate low oil pressure= BIG BUCKS. I would have a qualified repair shop check it out, A shop that specializes in BMW. If you are lucky, maybe the oil sender is just bad. They can also check out the Ck eng light. But the oil light is priority one.

Faulty Heater Fan


I would check the blower motor resistor. The resistor slows the current going to the blower motor to make the fan run slower for the first three speeds.The high speed runs of full battery voltage.I hope this helps.
