So I have an 87 325e n its leaking coolant from the back of the bell housing
Where it bolts to the tranny only after it has been drivin. No other signs of leaking anywhere elts. And lots of over heating. Any idea what is wrong?
Check the coolant hoses to and from the heater core. Probably one of them is leaking coolant onto the back of the engine block and its running down. There is no way coolant could be coming out of the bellhousing.
