Hello my dakota squeals from the point I start it till I turn the engine off, and gets louder with increase of rpms. I've replaced the belt, belt tensioner, idler puley, a/c clutch bearing and cleaned all puleys. So its either the water pump for fan clutch that has a bad bearing i'm thinking. Any help would be helpful.

 

Carefully crawl under the truck while it's running. You should be able to tell if its louder at the water pump from below. Check for seeping coolant in the weep hole on the bottom if your pump has one. With everything you've done seems like the water pump is likely.

 

well i just replaced myn and shes doing the same thing just not consistenly wich make me think myn is the fan ? but im not sure

 

did you ever figure out what was making the noise?

 

yeah it was the water pump, the bearing went out and the water pump wasn't but maybe two years old so these dakota must have isuses with the water pump bearing going out.

 

never heard that one before. mine is on 110k+ miles and there haven't been any persistent water pump complaints here on the forum...

 

waterpump bearings usually go because of lack of coolant.
