About Josh Fields Expertise I can answer questions related to the BMW e30. These are the cars produced from 1984-1991 (1992 for convertable) in the United states. I am more fluent with the six cylinder models, although few things changed for the 4 cylinder cars. I know most of the problematic areas of these cars, and have found ways to fix them.
Experience I have owned six different E30's over the last 10 years. I do all my own work, and know about ever nut and bolt on these cars.
Question My 1988 735i is leaking coolant from the heater core. My mechanic
says it cannot be bypassed so I do not have to replace the heater. Is
there any way to do this as he wants $800 to replace the heater
Answer Tim,
I am not familiar with the 7-series like I am with the 3-series. I dont understand how it CANNOT be bypassed, as there are usually 2 hoses that run through the fire wall, into your heater core. One hose is for coolant running into the heater core, and the other is the return line. If you disconnect these lines at the firewall, and connect them together, you are pulling the heater core out of the loop. I would locate these lines, and see if it can be done. Unfortunately I cannot tell you exactly how to do this, because I'm not 100% sure how the heater lines run on those cars.
