The original question is why he's running hotter than normal.
newly built engine, that is just breaking in. I brought it up about the electric fan, the gains aren't proven theory. I have even heard the electric fan will cause some loss HP too. I'll stick with my Trusty -20 HP Flex Fan and run cooler not worry. It's OK to believe the hype of someone who's paid by the company who makes the fans. Answer this, if the electric fan is so much better than the Flex and clutch fans, Why doesn't GM, Ford, Chrysler, and the truck makers use them on all their vehicles.
