Like the title says, once I get above 2000rpm or so I get a nice loud fan sound. Sounds almost like a clutch fan but realllllly loud. Any ideas???

go try and spin your cooling fan. if it won't go, the clutch is blown. Mine went a while back, and every time I accelerated, all I heard was a loud blowing "whoooooom" noise from the motor. the clutch had seized so it didn't disengage like it should. If your fan spins free, the clutch is bad, if it won't spin without alot of force, it is bad, if it just resists a little, it is fine. If it's bad, just go to a parts store and buy a new fan clutch and bolt it in. Good luck.

Thanks guys. I will try that tomorrow. Exhaust leak I know it isn't. Just replaced the manifold gaskets and all other stuff is fine.

Any other ideas to look for?

what does it sound like? Is it the "whoooooooooooooooooooooooooooooom" sound as you rev up, like something pushing alot of air? is it metallic? Mine sounded like a small motor revving up when it went. good luck.

Yeah it sounds like a lot of air being moved when it gets up in the revs. Way louder than it ever used to be. Just started doing it as I left work yesterday.

No problem. Best bet is to replace it with a stock clutch unit. Don't get a flex fan or anything like that. The clutch should run you around 40.00 I think, and it bolts into the plastic fan blades. Shouldn't take more than 30 mins. to fix. Take it easy on the RPMs until you do, because you now have alot of resistance on your water pump because the fan won't disengage.
