No worries. I will do some research. If it's a mess than I will not be doing it.

Thanks

 

I have been taking the whole front apart and doing some TLC.
I noticed oil/Grease on the fan and on the clutch (pic). i am not sure if there are any grease inside the Viscous Clutch. I dont see any oil behind the fan. But there are some leaks from Valve cover and may be front seal.

I am waiting for parts to get here by Thursday/Fri. then swap the fan as soon as possible. in the meantime not driving the truck.
