318ti.org forum - View Single Post - diagnose my problem... no heat, engine overheating

**wolferj-RIP** · 10-20-2008, 03:50 AM

Please help educate me on this... If he hadn't done any work on the cooling system (or at least he didn't say so...), why would he need to bleed the air out? Is there an underlying problem that allows excessive air into the coolant lines? It just doesn't make sense (but that's why I would like enlightenment).

Just from an engineering standpoint, the water pump not circulating properly would cause these symptoms. A thermostat locked in the closed or open position would not cause all the symptoms he is experiencing... Would an airlock in the coolant system cause all these issues simultainiously?

But I really don't know... just taking my best educated guess... (and trying to help!)
