my radiator fan began making a strange noise at around 50 hrs, it has 100 hrs on it now. I checked the spot weld from the fan bracket onto the radiator and it is fine. It is just when the fan is running it sounds like there is a loose bolt or something. does anyone else have this problem or had it and can give me a lil help?

 

Check the ring around the fan blades, mine had a build up of dirt from going thru the mud and this threw it out of balance making a strange noise.

 

thanks for the reply
can u tell me how i should go about that?

 

hit the fan with a pressure washer and get all the built up mud and junk out of there and see if it still makes the noise. If it dus then either your fan bracket is loose or there is a bolt that needs tightening. my dads fan bracket broke and punctured the radiator, and after that was fixed some bolts around the fan loosened up and made some of the oddest sounds. just go through and tighten up all the bolts and check all you brackets. probly just a couple bolts holding it in place thats all/
