Fan coupling

The coupling of the fan is achieved by the drag of viscous oil between two plates, I don't believe it will have hurt the coupling.

Might be idea to replace both fan and coupling unit prevention better than cure.

Only say this as when having bit of a extended trip back in 2014 came across couple with isuzu 4wd truck with camper had a fan blade disintegrate whilst traversing Bungle bungle track back to hwy.

One week later waiting for new radiator to arrive ex perth at Halls creek wrong radiator two models and bolt shape pattern changed mid manufacture period.

In short better play safe than be sorry and have greater issues occur when out remote with bugger all assistance.

Muzbry - Here's a simple test for the viscous fan coupling. Shove your fingers in the fan, when it's running.

If the fan stops, the VC is shot. If you lose several fingers, the VC is good to go, for another 100,000 kays!

Would I lie to you?? Here's the video to show you how! [;-)

(Seriously, if the VC is leaking oil, or if there's visible movement in the shaft, or if the fan turns really easily when stopped, then I'd suggest you suss out a replacement.)

Cheers, Ron.

Thanks fellas, i'll go for the "fingers in the fan" method of testing . Should be a lot of fun.

I'd be more concerned about any overheating of the engine rather than the viscous fan...
