Water pump Spanner wrench, which one?
I'm changing out the water pump on my '97 Dodge Ram 1500 (5.9 liter) and wondering what clutch fan tool people are using? (ie. one with spanner pins spaced at 4 1/4")
I purchased the Lisle 44180 Fan Clutch spanner wrench ahead of the job, but it doesn't appear it's the one. Noting there are two sets of pins on this tool, one pair spaced at 2 1/2", the others at 3".
Just to note, the factory water pump was still on the truck, which (for those who may not know) does not have holes for spanner wrench pins, the pump pulley is bolted (with 4 bolts) to the pump. Easy enough to remove the fan by placing a screw driver across two opposite bolts to hold the pulley, then using a (36mm) wrench on the large clutch fan bolt.
Anyway, looking at the replacement water pumps (even the OEM Mopar pump, PN# 53021018) the pulleys are not bolted as original, and a spanner wrench will be needed to reassemble the clutch fan. HENCE the need for a spanner wrench. If anyone can confirm the hole spacing on an OEM (replacement pump as shown below) please let me know. I believe this spacing is 4 1/4" based on measuring an ACDelco (PN# DEL 252-1025) replacement pump.
Thanks in advance for any info.

Thanks for the replies. Maybe I wasn't clear in my original post, I'm looking for what SPANNER TOOL with pin spacing of 4 1/4", not the large (36mm) wrench for the clutch fan nut.
I had no difficulty getting the (36mm) nut loose, again noting the original water pump pulley was BOLT on. Most of the replacement water pumps have PRESS on pulleys (and holes for a spanner wrench) that's why
I'm looking for what spanner wrench people may have used to hold the pulley while replacing the clutch fan.
Also noting, I've seen many references to use the Lisle 44180 spanner tool, but it has pin spacings of 2 1/2" and 3"............ but the hole spacing on the pump pulley is 4 1/4" (center to center).
If I don't find the proper spanner tool, then I'll go ahead and use a strap wrench (or belt in place to hold) but I'm holding out hopes I'll find one. Yes, there are spanner tools out there that are 'adjustable', but that comes back to my question, if someone has used one, I'd be interested to know of one that did work.
Thanks again,
Kevin
