2000 Dodge Dakota Belt and pulley problems

2000 Dodge Dakota

I recently installed a new serpentine belt on my 2000 Dodge Dakota. Now, after about a month of driving a squeeling had come about. So I checked all of my pulleys and realized the bearing was shot in my idler pulley, so I replaced it. The squeeling continues. It doesn't seem to be a problem with my tension puller either nor is the belt shot by any means. So I removed the belt and rotated all of my pulleys and it seems as though a small, but almost non-existent, squeeling is coming from my altenator. I'm also losing no power whatsoever to my truck. Is it possible just the pulley on my alternator is shot or could it be from something else?

Hi, Look At All The Pulleys, Make Sure That No oil Or anti freeze is Getting on them. Do Not spray Anything On the belt. If The Belt Tensioner Is Orginal, I'd Replace It. They Do lose Their Tension After a while. You stated that When you Spun The alternator Pulley You heard Something, One: It could Be The alternator Bearing May Be Going, Or It Could Also be the brushes Inside the Alternator.

Hope This Helps You,
Good Luck

It's funny you mention the anti-freeze because about when the squeeling began my truck was smelling of burning anti-freeze. Now, that problem was fixed pretty quickly but could that have ruined my new serpentine belt or what do you figure? Tomorrow I plan on replacing the belt tensioner just to remove that from the equation but any other predictions would help. Normally I can pin point the problem right away but this one is stumping me.

If Any Anti -freeze Got Into The Belt, It Will make Noise. You Cannot Clean The Belt, It Must Be Changed. Once Antifreeze Or oil Gets Into the rubber, It Will Make Noise. Also Make Sure The Pulleys Are clean And Dry, Before Putting On the new belt. Look At the bottom Of The water pump, There Is a Hole Under The Pulley If you see a Antifreeze Stain Or Wetness, Then The water Pump Is Bad. Use a Small Inspection Mirror Too Do this. Some Water Pumps Will leak With car Running, And Under Pressure, And Some will Just Leak When Car Is not Running.

Hope This Helps You,
Good Luck
