I've attached picture steps below on how to remove and replace both the engine and A/C serpentine belt for your truck. Hope this helps and thanks for using 2CarPros.

Installation Procedure

1. Install the drive belt.

2. Route the drive belt over and/or around all the drive pulleys except for the tensioner.

3. Install a 3/8 inch breaker bar into the tensioner opening and rotate the tensioner counterclockwise.

4. Install the belt over and/or around the tensioner.

5. Slowly release the tension on the tensioner arm.

6. Inspect the drive belt for proper installation on and/or around all pulleys.

7. Position the engine cooling fan shroud on the 3 mounting brackets (1).

Hello, I'm Danny.

If the pulley bolt is stripped you will have to remove the whole assembly to replace. Here are a few tutorials to view showing how to replace the serpentine belt and tensioner:

The manufacturers say if there are more than 3 cracks within one inch, it should be replaced. However, I find that hard to believe. On average, people usually get about 35K out of one. Remember, if there are superficial cracks in it, in my book that is normal wear. If it starts cracking through the threaded part in the middle, I would recommend replacing it.

Let me know if you have other questions.

Water pump pulley is not your problem, most likely it is dry alternator bearings. Remove belt and spin alternator pulley and see if it squeeks. Hope this helps.

Hello,

You cannot tighten the belt it has an automatic tension-er on it.

But before you go ant replace it here it something to try.

Find the location of your tension-er pulley and your idler pulley then with a spray lube and the engine off spray the center bolt of one of the pulleys. Then start the vehicle. If noise is gone for short time then the bearings are going back and you will need to replace that pulley. If noise is still there then turn vehicle off and spray other pulley in same manner and restart if noise is gone for short time replace that pulley. While doing this also watch the tension-er assembly for excessive movement. Also, when was the last time you replaced the belt? An old worn belt can cause the squealing also.

If you need diagram will need more info on you truck.

Is it a 1500, 2500 etc and is it 4x4 or not and engine size in liters.

Here are the diagrams:
