This means that you need to have your belt replaced. The sound is coming from the belt itself because it is worn. The belts are not too expensive and are fairly easy to replace if you are a DIY guy.
Thanks for your help I just wasn't sure if it was more than the belt ie. tensioner or water pump etc. but I change that belt out see if it cures the squeeling.

Does the squealing noise only happen when you accelerate? It may be the serpentine belt. If you look at the belt on the inside where the grooves are and the belt is all cracked up, then I'd start with the belt.
Misalignment of the belt, incorrect belt, worn or loose tensioner, Too tight of an adjustment (many service centers do this on purpose so when the belt breaks in it becomes properly adjusted, I do not believe in this philosophy), The belt is actually one long belt called a serpentine belt.....
Are you sure you don't hear anything like a chirping sound when the engine is idling? Have you popped the hood and listened while the engine was idling? Have a friend sit in the driver's seat while you pop the hood, tell them to press the accelerator and then listen for the squeal. I would bet dollars to donuts the problem is the serpentine belt is worn and needs to be replaced.
Check the idler pulley on the serpentine drive belt,it's mounted on the passenger side timing cover close to the cam gear,and could transfer the noise through and make it sound as if it coming from inside,and it's an easy check and requires no dissambley.I've had personal experience with this in my professional trade,I do industrial maintenance and repair and have seen bad bearings transmit noise down the lenght of a solid 8' shaft.Loosen the tension on the belt and check for play in pulley,spin the pulley and see how it feels,should have a smooth feel.Go to autzone.com and register they have a good online manual for your truck that you can download and print.
