diagnose my problem... no heat, engine overheating Hey guys - I'm kinda a noob w/ BMWs, but I figure this can't be too complicated. Diagnose this for me: Symptoms: (1) My engine is overheating. No lights come on. I did get smoke/steam coming out of it tonight. Coolant levels are fine. Oil levels are fine. (2) My heater doesn't blow any warm air. I assume I just need a new thermostat, but the overheating concerns me. Could the water pump be going bad too? Is there a way I can figure this out on my own? Thoughts? Thanks! Scott |
