2007 Sportscoach Fan Clutch

My 2007 Coachmen Sportscoach Legend is having overheating issues. ISL 400 Cummins. Noticed that the ECM controlled engine fan running fairly slow. Even with high temps the fan wonít speed up. Raising the rpms do not help. I disconnected the power to the fan clutch hoping it would default on high. Unfortunately the fan stayed slow. The radiator is rear mounted so doing repairs is terribly involved. Tried turning on the A/C which should have sped up the fan, but it did not speed up. Stuck in Cincinnati!! Any feedback is greatly appreciated.

Some of the old Horton fan clutch hubs had a couple of places to put two 5/16 NC bolts in to lock up the hub.

Maybe there is something like that on yours.

Good luck and Happy Glamping.
