My '01 4.7 has a loud fan right now. It seems like the fan is stuck in the warm-up mode, like when you first start the engine. Is the fan clutch bad? How do I go about replaceing it?

 

it sounds like the fan clutch is stuck. one way to tell is to just try and spin the fan. there should be a bit of tension on it. but I think you will have to buy the whole fan to replace it. I dont know if you can just buy the clutch buy its self or not.

 

Thanks for your help.

 

If you are going to have to replace the clutch, look to see how much it would be to buy an electric setup.

Just my $.02

 

I have an 02 Dakota 4x4 with the 4.7 as well.

It was in a wreck (clutch fan is messed up).

Ijust want to run an electric fan on this (no clutch fan).....

I have the big nut cut off the clutch fan assy
in case I would need toinstall it on the water pump pulley.




Is there anything special i have to do when doing this?




thanks in advance

hooking up an electric fan is fairly easy. you can buy the kits to convert it but there pretty expensive. I was thinking on putting an electric fan on mine over the winter. you can just hook it up to a toggle switch and then you can turn it on when ever you want. I'm not sure how you would hook it up to a sensor to turn it on automatically though. and mounting it is pretty easy. just get 2 pieces of flat bar and run then across the rad. then bolt the fan to it and your set.

 

Flex a lite doesn't have a set up for us yet, but they did tell me to run
the 290 (i think....)...

this fan is for the ford mustang, has a shroud, pulls
twice as much air (and if it can keep a 5.0 Mustang cool, then i would think
it would keep our 4.7 cool).......

only bad thing is.............it cost over $400.....ouch

I am going to the boneyard and gettinga fan assy off of a TransAm or Mustang ($50...plus you can get replacement motors seperately cheaply).
Then you can get a coolant fan sensor from GM that will close its contacts at
a certain coolanttemp...with that, you can control a relay that will supply power to the fan......turning on the A/C will still activate it as well.....
