Loud fan...
 

The fan in my car is really loud. The more throttle the more loud fan noise. Does anyone know what causes this or how i can fix it?

The clutch inside the fan has seized. Don't drive it and if you do try and keep the RPM's as low as possible or you will seize the bearing in your water pump and need a new water pump too! The clutch is very very simple to fix and at your local parts store. You need a thermal fan clutch, not a single speed clutch.

Simply take off the belt and unbolt the fan at the post. Unbolt the clutch from inside the fan, bolt the new one in and viola!

Alright, thanks man.

Make sure you tighten those bolts on the fan really good. I had them loosen up once. The engine vibration felt in the steering wheel was unbelievable! It destroyed my water pump in one 5 mile trip.

It could be a good time to convert to an electric fan! It's pretty simple.
