I am R&R-ing my waterpump on my 97 sport, 5.2. Does anyone know the clutch fan nut size (the big nut that holds the clutch to the wp)?
Many tks in advance,

36mm.

I just did my timing chain, and I was able to borrow a set of fan clutch wrenches from my local O'Reilly Auto Parts. (They call it a "free tool loan", but they actually charged $89 to my debit card, then refunded it when I returned the tool.)

 

leave the belt on, crescent wrench, hammer. It's normal thread as I recall. Three whacks and it should come loose.
