How to Replace the Fan on a 2001 BMW 325ci


1. Purchase an appropriate replacement fan for your 2001 BMW 325ci.
2. Lift the hood and prop it open. Find the engine fan in the front of the engine, above the radiator. The fan is attached to the water pump by a fan nut.
3. Attach the 32 mm wrench to the fan nut. Hammer the 32 mm wrench clockwise to loosen the fan nut. Remove the fan nut and put it aside for attachment to the new fan.
4. Spin the fan clockwise because the fan nut has a reverse thread on it. Loosen the fan with your hands until it detaches.
5. Put the new fan on by turning it counterclockwise to attach it to the water pump. Tighten the fan nut with the 32 mm wrench. Close the hood.
