Just check STOA, CAT or any club site. All good reads! I think the first place to start is knowing what the actual engine team really is. We all know that the original temp guage can be off. The other thing is: as a dyed in the wool ford guy, 185 degrees is the optimal engine temp. But, Ford engines can get to 195-200 degrees easily and that is not necessarily a bad thing. Yes, I put a pusher in mine only because I had one. I’m not really sure is does anything. My original guage can show 225-230 on a hot day (humidity plays a bitg role) but never has pucked out fluid. The design of the should is an issue. It lets hot air from the engine compartment to get under the radiator. Many, many, ‘fixes’ that can be done. However, on a hot low humidity day.. well good luck.
