Homemade Fan Nut Tool (water pump pulley holder) w/Pic

There are a number of methods to immobilize the water pump pulley when loosening the fan nut with a 32mm (or 1-1/4”) wrench. I tried "hammering-the-wrench", screwdrivers, etc but nothing worked for me, so I easily made this tool, which some may find useful. The nut loosened easily right away.

It’s just a piece of aluminum bar (1” x 1/8” x 36”) with a 1/2“ diameter hole drilled near the end (approx 1/8“ from one side of the bar) for fitting over one of the 10mm water pump bolt heads.

I bought the bar at Home Depot for about $6. Aluminum is a soft metal, so it was easy to drill through it with a standard 1/2” drill bit. Just took a couple of minutes to make. It’s best to aim at having the hole about 1/8“ from one side of the bar, so that it fits easily between the bolt and the axis of the water pump behind the nut. (My drill bit drifted a bit, so the hole in mine was almost in the middle of the bar [~1/4” from the sides]; it still worked but closer to the side is better.) The aluminum bar is softer than anything it will press against, so nothing will be damaged by it. And the bar can be flexed outward to avoid the thermostat if needed. This long bar gave a lot of leverage, but shorter bars are also available at HD if you prefer. Below is a picture of how the bar fits over a bolt (of course, the fan with nut was removed to allow this picture).
