Sorry, I forgot to add the heater has been bypassed. Why? I don't know, was done by previous owner as it was a farm car and since he's 92 and in a rest home I didn't get to meet him as the car was sold on behalf.

People often do this to temporarily "fix" a leaking heater core. What color and KPa marking does the coolant overflow bottle cap have?
