strange sound from fan area

Kelly Goosecock · 07-02-2009, 07:35 PM

Ok so the truck is still running perfect, except for a strange sound that started out of the blue. It's like a loud whirring sounds that gets louder with engine speed. I'm not sure you can even hear it. But up higher in the rev range it's fairly loud. I think I'm maybe even hearing some light metal sounds as well. Is my fan done? Anyone?

ok after doing a search I think it's probably the fan clutch. Should I be able to turn the fan by hand when the engine is off? because I can't.

Sounds like a roar when the clutch is stuck and it gets really loud when first driving off.

x2 on your fan clutch being shot. You should be able to turn it with the truck being off and cool.

my 95 makes the same noise that your describing, when i take off from a stop the thing sounds like a transport. gets worse in higher rpms, i have a glass pack muffler and the noise is way louder than it but my fan spins fine when the truck is not running. i plan on putting in an e fan and a set of underdrive pulleys soon.

my 00 jimmy did the same, sounded like a jet taking off for a second or two then it went away.

parents blazer was the same when that had low miles on it

i just took that peice of junk off and replaced it with an electric fan.

i have a 2.2 so i got a 2.2 cavy fan and it stays the same temp and cools pretty good for the $20 i spent
