Exclamation Removing radiator fan without special tools?

Does anyone know how to remove the fan without having to buy these special tools?



Any help is appreciated, thanks!

Are you trying to remove the fan, from the fan housing itself?

You can't remove the fan without, at a minimum, a 32mm wrench. The wrench has to be just long enough to clear the fan shroud. The one I use, just because it's thin, is sold as a bicycle repair wrench. On mine, I put the wrench on it, tapped it with a hammer to the right and it loosened right up. Where that hasn't worked, others have jury rigged it so the pulley wouldn't turn while using the 32mm wrench. See this picture (borrowed from Beisan Systems excellent vanos repair instructions):

I have been successful counter-holding the fan pulley with a very long screwdriver - using the shaft of the screwdriver to hold the pulley by the bolt heads. A little tedious but it works.

I have done the wrench and hammer trick as well as the wrench and screwdriver trick as described above. At some point, you will come across a fan clutch rusted or otherwise seized onto the water pump that a proper fan holding tool is the only way to break it loose. For what its worth, I never had problems with fan clutches until I started working on E46s so I finally got a water pump tool.

Would it be a good idea to put some anti-seize on it when re-attaching the fan or would that cause problems?

I haven't seen any recommendations for anti-seize for that. When I took my fan off at 52K miles, as far as I could tell that was the first time it had been off, and I didn't need the special tool at all. Just tap, tap and it loosened right up.

I always apply antiseize to the water pump threads so the next guy working on the car can remove the fan clutch.

Use regular 32mm wrench when the engine is COLD. The belt holds the fan better when COLD. I've done it about 5 times without any special tool.

If it is stuck, you can use a big punch with a pointed end and line it up on the edge of the nut. Strike it a few times pretty good and it should break free.
