More mature BMW styles like the E30 325i did not have a cooler. H. Return Hose, aka "Radiator Return Line". BMW has two hoses they contact a Return Line. We're going to clarify issues and get in touch with whichever hose attaches on the reservoir could be the Return. "File" while in the diagram we have been re-naming the Outlet Hose.
