As a part of winter prep, I bought a cheap blower motor and flushed the coolant. The coolant was looking, not the best. I didn't want to wait for BMW coolant to ship and I used a brand name from the local auto parts store. Now begins the issue. I never had trouble bleeding the system, as it is a late model and I usually park on a hill. So I just crack the bleed valve and done.
I don't have heat at idle and I believe it will warm up (past operating temp), very slightly. I have tried to burp any air out. I have heat when I am moving around or the RPMs are high. But at idle or sitting in traffic the air coming out is cool. Yesterday, I thought to keep bleeding it, noticed the clutch fan is very loud. Like Nissan SUV or Semi/Large Truck loud. It sounds like air movement not like a bearing. (There is belt squeal but temp went from 60 to 16 this morning, so I am fairly certain it is the alt belt, tension has not been adjusted in a couple of years)
Could a bad fan clutch cause no heat at idle? Fan does spin. It seems to wobble though. Or am I looking at replacing the water pump too? Water pump is a GRAF metal impeller unit, less than two years old.
I just don't have the cash to replace both at the same time. Life problems. I do have a project 30, I may buy a new water pump and pull the clutch fan off the other e30?
Just wanted feedback from someone more educated.
