Which way does coolant flow through heater core?
BMW E91 320i.
I think my heater core is clogged and i'm trying to figure out which way the coolant flows. I'm guessing it's this way? If I power the aux pump manually with 12v, I can hear it run dry, which I think is strange because I'd expect the coolant to sit in the pump and not go any further.  |
