Engine fan
I have a 2006 Monaco with a 8.8L 400HP Cummins side radiator . Recently I noticed the engine fan is running full speed all the time . I know the fan is driven hydraulically and I think it thermostatic...

Agree completely. Those side rads can totally become clogged with junk after a nice trip. Especially if you happen to any offroading areas, dusty areas, or areas infested with bugs!
