It's been awhile since I've posted but still been lurking occasionally. I finally got some ambition to work on the car and was kind of stumped by this. The engine is a 72 olds 350 and the heat and AC are bypassed. The line I'm questioning runs from the back of the intake to the small fitting on the water pump. I always thought the small fitting on the water pump went to the heater core so it would always be flowing coolant for the heater (not going through the thermostat)? I'm wondering if I need this line still or If I could plug the back of the intake and cap the small fitting on the water pump?
