Like the home-made subframe & differential bushing tool, this fan-counterhold water pump pulley tool seems easy enough to make and/or buy so I picked up a set of them last week for both the I6 & the V8 (viscous fan only).

This tool has both the 45mm (V6) hole spacing (which was previously measured) and the 38mm (V8) hole spacing (which was never measured before); also, this tool is for "viscous fans" only (I suspect the indented tool pictured in a post above must be for non viscous fans???).

Here are the measurements I made using a variety of calipers, micrometers, and just a plain old steel ruler (marked off in 1/32" increments).

I don't have the skills to do a CAD drawing but hopefully someone else can draw the combined tool so any good DIY'er can drill and saw his own out of steel bar stock.

PS: Why do all the stickers say the tools is for viscous fans only; what happens if you use water pump pulley counterhold tool on a non-viscous fan?
