Heater Core Flush
Hello All,
New to this forum and have a question - probably elementary to some, but need help!
I have a 1999 528i (E-39) and i believe the heater core needs to be flushed...heat is not what it used to be - rather low. From my research, it seems pretty easy. my question is, how do i know/identify which is the 'intake and outlet hose going to the heater core?
