BETOOLL 8PCS Pneumatic Fan Clutch Wrench - 43300 Removal Tool Kit, Auto Repair Spanner Kit Installs Compatible With Ford, GM, Chrysler and Jeep

So much easier than the old way. Even works with the small air hammers. Couple of ugga-duggas and fan spun right off.

Worked great on 2016 F250. I may have had to remove some paint to get it to engage in the air hammer chuck. A fine tool for DIY but daily use would probably break it as other reviews have noted. Up to you to decide whether you want to spend a lot on a tool that will last for a long time or a little on a tool that will last a short time.

I have a 2004.5 GMC Sierra Duramax. I have a shade tree mechanic that is quite good. We bought a special 1 7/8 inch wrench from O'reilly's for almost $50 to knock the fan clutch nut loose. Autozone had nothing. I watched all sorts of videos of how to stop the water pump from turning. He tried everything he would imagine and none of the special tricks worked. I finally saw a video on this tool and ordered it. I tried to put it in my hand chisel impact gun but it was too big by a couple of thousandths. I took a fiber abrasive wheel on an angle grinder and removed all the paint from the end that goes into the gun and had a perfect fit. I put it on the fan clutch nut and pulled the trigger with nothing to hold the water pump from turning but the serpentine belt. In less than 5 seconds the very stubborn nut was free. I was totally amazed. I saw reviews showing the impact shaft damaged. To me it is well built and I cannot understand how to break it when using it as it is designed to work. I saw one review where the fork end came off. That would not be a problem for a welder with a wire feed to put it back on even stronger. I simply cannot figure out a way to break it using it as it is designed to be used. If not for the paint issue, I would happily give it 10 stars.

This tool was able to remove a very stubborn fan clutch where the previous tool, also from Amazon failed on the very first try. See photo. The Betoll product (with the red label) withstood countless beatings while the previous tool bent wide open with little force. The Betoll hammer driver shaft is heavily reinforced where the other tool snapped on the first try at the cheap welds. I feel I now have tool that will last years.

Good tool

Broke first use unfortunately haven’t used it well after return pin fell out lock pin on hammer tool by the one with the Drive holder good price thought it was a deal. With the holder it’s easy to torque the new fan clutch used it on a Dodge 67 Cummins

Did what it needed to, just be careful in making sure the wrench part doesn’t fall into engine bay
