[QUOTE=Steve Nmaeth]I need some help. My alternator went out on my 91 525i. In the process of replacing the alternator I had to remove the top radiator hose and drain some coolant. Since then I have had no heat. Replaced thermostat, thermo housing, water pump has metal impeller, replaced heater valve, auxiliary heater motor works well, gone through 2 gallons of cool blue in bleeding, no leaks in coolant system, still no heat. Any suggestions?[/QUOTE
On my M20 powered 325is it took a good rev to purge the air despite all other attempts. Have you been driving the car much? Any other symptoms? Overheat?
