Removing fan assy.

Does anyone have a trick or method they use to hold the water pump pulley when turning the large fan nut when removing the fan? I will be using a Matco type removing wrench that uses a air chisel to loosen the nut but in the past I have had to try to hold the pulley because even with the belt still on it wants to turn when getting the nut loose, Thanks, Fred

Use a Fan Clutch wrench on the 4 bolts on the water pump pulley, then use a big pipe wrench on the fan nut itself. It's standard right hand thread. Having a friend hold the fan clutch wrench helps out a lot.

This particular wrench only fits the large nut and has nothing to hold the pulley nuts with....maybe it will bust loose without holding the pulley seperately......if I'm lucky......Fred

I usually tap the big fan nut with a hammer prior to trying to break it loose. It has never failed me. Also put a box end wrench on one of the pulley bolts and hold with one hand while pushing with the other....Its a pain in the ars!

At least you are working on a pickup truck. The vans don't even have enough room to get 2 tools in there at the same time, the fan clutch shaft is about 1.5" shorter.

I think that the tool the original poster is using should have come with a holding wrench as well as the wrench for the actual clutch.

Autozone or Advance will have a clutch tool you can rent. You get your money back after you return it.

I always put an old belt around the pulley, then have someone pull on the belt, if it goes at least 3/4 the way around it will hold the hub. But you have to hold it tight

If you have the one that uses the air chisel you will just have to keep your belt on and tight. They work slicker than $hit. I love mine. I use it on anything that it fits.

I had to end up putting a large screwdriver between one of the pulley bolts and fan collar and hit with the air chisel/Mac wrench removing it....it would still spin with the belt on and no retaining of the pulley....came loose instantly after retaining the pulley.....Thanks to all for your suggestions, Fred
