Aluminum Fan Removal
I did a search for the best method of removing the fan from the water pump shaft without results. Please let me know the best method you have found to remove the fan. It is on there pretty tight. I do not want to mar the shaft or the fan. BTW- I filled my cooling system with vinegar and let it sit for a few days to clean it out. Drained and flushed using baking soda, and refilled system. Started up the A and the sealed bearing squealed in the leakless water pump. Maybe I left vinegar in the system too long or maybe this is not the best method to clean the system. Oh well, live and learn! Thanks for any advice you can give.

Re: Aluminum Fan Removal
I've only found this at my local Farm and Home and not any parts stores or Walmart. Motor Medic Radiator Anti-Rust & Water Pump Lubricant.
The manufacturer of my leakless WP recommended this upon filling the radiator back up after installation of the WP. It might help.

Re: Aluminum Fan Removal
I was not having any problems with the cooling system. Once a year I drain and refill the system with water and water wetter. It has been a few years since I put any product in the cooling system to give it a clean out. Tried the vinegar method this time with poor results.

Re: Aluminum Fan Removal
The vinegar can loosen things up in the block and then the debris will clog the radiator. Hopefully this will not happen but there has been a lot of posts lately of overzealous use of vinegar. On a car with a good functioning cooling system I would just drain and refill it with 50/50. Fights corrosion and keeps things protected.
To remove the fan the suppliers sell a knock off tool or use a king pin lock pin nut which is the same idea. |

Re: Aluminum Fan Removal
UPDATE
I used a clam shell bearing puller and placed it behind the fan pulley. I took off the castle nut and replaced it with a thin nut and had it even with the end of the shaft to protect the threads. The fan popped loose after one half turn on the puller shaft. |

Re: Aluminum Fan Removal
We broke one with a puller that covered most of the pulley to try to distribute the pressure. Guess it was stuck more than the aluminum could take.

Re: Aluminum Fan Removal
Obtain a bolt with the same threads as the pump shaft along with two nuts. Screw one of the nuts onto the pump shaft half way. Screw the bolt into the other end of the nut tightly against the pump shaft. Use the other nut as a locking nut. Sit in a chair and place the fan across your knees, With a hammer smack the bolt a few times and it should come loose.
