 Strange fan #770599 February 02nd 2021 11:14 am | Joined: Jul 2009 Posts: 6,258 Likes: 164 Master Metal Sculptor | OP  Master Metal Sculptor Joined: Jul 2009 Posts: 6,258 Likes: 164 | I pulled the motor out of my donor van for the chopped Dodge and I looked at the fan and my first thought was several of the blades had broken off but apparently this is how they come. It seems like it wouldn't be balanced or move as much air if there were more blades and they were symmetrical. Any idea why they do this? Is it ok to switch to a different fan?

Change as you wish. I’ve changed to flex fans in the past, but I generally think the factory is smarter than I am.

Flex fans came into vogue on motors without fan clutches, as the flex fans blades flex out straight under RPM, lessening the load on the motor at speed due to increased air flow through the radiator at speed.

On my Dodge getting in the lower half of the fan shroud in, without removing the radiator hoses from radiator, without rotating that fan to accommodate, would be on the order of impossible. | | | Re: Strange fan | Joined: Dec 2018 Posts: 372 Likes: 16 enthusiast | | enthusiast Joined: Dec 2018 Posts: 372 Likes: 16 | I can’t imagine a scenario where I would pull the water pump or timing cover without pulling the fan first. | | | Re: Strange fan | Joined: Dec 2018 Posts: 372 Likes: 16 enthusiast | | enthusiast Joined: Dec 2018 Posts: 372 Likes: 16 | It looks to be for noise reduction. | | |
