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.

I have replaced every pulley, belt tensioner, and belts on my Chevy Silverado 2500 HD over a period of the last 2 years. I have no noise after each repair, but it starts squeaking again after a few minutes to sometimes a few days every time I fix it. Could something be out of alignment? It is very irritating to have the same noise come back time and time again.
I have had at least 5 different mechanics work on it and each time I think it is fixed, the noises come back.
The last time I put a new belt on, it went great for about 100 miles.
I washed the truck and the belt started squealing.
Then after it dried out it quit for a couple of days, but then started up the chirping again again. It gets worse as the engine warms up and is torquing up.

I also have a 2005 Silverado only mine is a Single cab work truck. My belt squeaks too, I have replaced the pulleys and the belt the squeaking stopped for awhile but came back. The only solution I have found is Brake Cleaner. I put it on the belt and it stopped the squeaking for two to three weeks but it is doing it again!

I had the truck in on warranty through GM for a squeeling belt at 18,000. They said it was glazed and replaced the belt. Everything was fine until 38,000. The truck went out of warranty at 36,000.I have replaced the belt 3 times in 3,000 now. I just replaced the belt tensioner and idler pulley and I still get the annoying squeel for about 10 minutes until the truck warms up then it stops.I noticed the flat pulley on the waterpump did not show even signs of wear. Half of the pulley was stripped of the paint from belt slippage. Is a bad waterpump my problem or a bad pulley?I sanded the pulley even now. It is all bare steel. Will this cause slippage?The belt still squeels. Please help or I am going to trade this truck in on a new Toyota. Thanks

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.
