Honestly i had no problems and my temp stays down when i am driving Its when i am waiting and waiting and waiting it wants to start going up . If i give it some Rpm it will come down . I have ZERO room for a clutch fan . In a perfect world my engine would be 3 inches back Unfortunately with the TH400 trans i just run out of room . I am kicking around the idea of going to a sm420/465 ? maybe even a TH350 we will see For now i am just happy that i can take it wheeling and enjoy it .flex fans are not great for slow speed. The flatten out and do not pull much air at higher rpms. When you are" in it" climbing an obstacle, your temps will raise due to lack of air flow. A fan clutch or just a stock "circle track" fan works great. It may take a little hp away but will pull air even more when at higher rpms. Flex fans are meant for cars that go higher speeds and they do not need a fan to pull air through the radiator, the speed with force it through. ON the trail, you will most likely never see speeds fast enough to push enough air to keep it cool.
