Re: Coolant leak - manifold nipple
Update: my heat stopped working a few days ago. I thought this was the issue. I fixed the leak and I'm full on coolant.
Heat still does not work. I tested the blend door actuator and it's working. I'm fairly certain the door is working properly as well. When I turn it to max AC I can hear something move where the door is. My next test was to check the heat valve. The hose leading from the manifold to the valve is warm. However, the hose on the other side of the valve remains cool after my truck has been running. Would this indicate a faulty valve?
