1992 BMW 325i Cabrio E30 M20 convertible here. Bought without heater hoses and possibly a leaking heater core. I am installing used and new parts for all now. I think I have the hose routing under the hood figured out except for one thing: Does the hose between the heater core and thermostat housing also Tee to the expansion tank?
I took the heater core hoses from a 1987 325i at a salvage yard. The hose from the heater core to the thermostat housing does not have this tee. The salvaged hose system does have the auxiliary thermostat, indicating the recall was done. Many drawings show the Tee to the expansion tank. See attached.
Thank you for posting any insight you may have on this.
