I'm starting to wonder if the water pump is weak since I could not see any flow in the radiator with the cap off. If I rev it with the cap off and see movement, perhaps the water pump is weak? Something has to explain why it cools perfectly while moving and starts to climb at idle; again, fans are running to the tune of a jet engine.


The FANS aren't needed when you're moving.... the airflow thru the radiator is enough.

Are your fans mounted in shrouds? Is there a gap between the shrouds and the radiator? Have you checked the voltage at the fans vs at the alternator?

What fans and how many CFM do they move? Do they both come on at the same time or are they staggered temp wise?
