Used to heat up coming off highway speed it does climp a little but the fans kick in and it goes right down to 185.
I'm running a mark Jones 467 .

I have the short water pump. This is the exact problem I have been running into when searching for a severe duty fan clutch for the short pump. I am going to mess with my stock system first and see if I can get it to work right, but if I can't I will convert to electric fans.
