I checked the stat and it is a 180 degree. So should I get a high flow 160? The Cap is a 16lb, Should I also get a lower one? The radiator is a new 4 core, so that should eliminate that as a problem. How do you check the water pump to find out if it is turning in the wrong direction? I have never heard of that happening. When the truck is idling in the driveway and you pull the cap off you can see the water moving a little but when you rev it up it moves a lot more and you see bubbles. Is that normal? Thanks for everybody's advice.
