Having problems with your 1999 Dodge Ram ?
Replacing waterpump. How do I remove fan assembly?
The large nut on the fan is threaded onto the water pump shaft. It's a counterclockwise thread. There are a number of different types of wrenches made especially to remove the fan. I usually just use a LONG punch and tap it into the nut to break it free. Once you make a small indentation (passenger's side from the top) give it one good shot to break it free, and then spin it off by hand. If you prefer to buy the wrench, that too is an option. Advance Auto (eastern U.S.) has tool rentals for a wrench that most DIY'rs are only going to use once. If you're uncomfortable with the punch I'd suggest renting one. Just remember that it's a reverse thread. Leaving the belt on helps in any event as it keeps some tension on the pulley to keep it from spinning.
