Need Help! 1988 735i -Coolant Leaking inside car, Heater Core?

A bad heater core or bad hose connection is about all that causes such a situation. Replacing a heater core can be difficult and time consuming. On the other hand, the task on some cars is rather easy. It all depends on what you have to remove to get at it.

coolant leaking inside my 1988 7351 BMW, a friend said it

Thank you Jim for taking time to reply. I will double check the hose connection.

I should have mentioned that some cars have all of the hose connections in the engine compartment. If this is the case with your car, then it is highly unlikely that a bad hose connection is causing your problem.

Hello Chris, It is a very time consuming job on the e32. If you are not to worried about having heat you can bypass the heater core. Simply take the 2 coolant hoses that go into the firewall which go into the heater core and join them together with a connector and 2 clamps. Other wise you will have to replace it. The part is around $300 and labor will be another $400 at least.. Good Luck. :)
