If I'm at the front of the car looking at the back of the block and down at the coolant flange/distribution inlet-outlet, even though mine has four ports, is the extreme right hand port supposed to be blanked off like it appears to be on the attached pic.
Because ATM, it's going to the bottom heater matrix. Is that right? I'm trying to get the last hose connected (RH thermostat port) and I'm wondering if I've got the wrong hose connected somewhere. Any thoughts please?
