Because you have to take more stuff off to get to it.

I did it on chicky when I got her. I probably posted how long it too me to do it back then. IIRC ~3 hours is about right compared to ~1 hour for a serp belt truck.

Re-resurrecting this old thread again. 97 4.0 serp belt is tight. Fan is tightly bolted to viscous. Engine off. Fan assembly feels loose, can move it front to back 1/16 inch or so. It looks like there is play in the viscous where it bolts to the waterpump.
Am thinking it is a bad viscous rather then water pump. Is that possible, or is it just a head-fake and its really a water pump going bad?
None of the viscous threads I read talked about looseness of fan.

Mine is a '94 3.9, but my fan was loose as described above and it was the fan clutch (not the water pump). Replaced it and all was back in order.

I suppose that is possible. The bolts could back off, the fan clutch could be shot somehow. Easy enough to remove the fan clutch to check, but I would be on water pump.

Mine was wobbling 1/4",
The pump was shot, so I did that and the fan clutch at the same time.
