3fe fan clutch

[Bambi]

hello 3fe fellows,
at what temp should the fan be fully engaged ?
my tamp gauge ( inside the upper radiator hose) is showing 104 C
( 220f) and the ambient temp is 34C (93 F)
but I don't hear the famous "roar ". so what real remp that roar should be on?
thx

I don't recall the set temp for the green Aisen hub. i would say 200F for the clutch to be fully engaged, can't remember now. But if your upper hose is @ 220.F. it is running pretty warm. 190F is the about avg. on fully warmed engine. I would replace it with new Green hub asap
