Serpentine Belt Replacement on a 2006 Chevrolet Silverado (and any GMT800 V8)

[M.Cueva]

the belts usually cause slippage and the retarded noise. mine went away after the dealership replaced the belts. Funny thing is that they replaced the belts 4 times under warranty so I guess the OEM part sucks...we shall see if it squeals this winter...if so, it is getting replaced with the highest quality belt that I can find...

were you having the squealing, or was it just time to change preventive maintenance style..

Just time for pm'ing the thing and we needed a write up.

My GMT900 is squealing on cold starts, and I'm wondering if it is the belt.

Thanks

It is probably either the belt, or one of the tensioner / idler pulleys.
When you change the belts...check all of the different pulleys REAL GOOD for signs of a bad bearing.

I just need to check into it. The belt looks fine, and I have a hard time believing the belt on my 2007 truck would be bad.

I brought it to the dealer in for some other warranty work, and they "couldn't duplicate."

Nice write up Jarrod.

I didn't realize they switched to 145 amp alternators. When searching for a belt for mine, they ask if I have the 130 amp or the 105 amp. (Mine is 130) I wonder if the 145a can be swapped in place of the 130a? Rockauto has the same belt listed for an 06 silverado w/145a and a 01 Suburban w/130a. If so, I'm sure a lot of 99-02 GMT800 owners will want to do this to gain a few extra amps. Here is my alt, its the original one and its stamped
"130A", I circled it in red.

Picked up both tensioners and both belts today!

As soon as I can leave the wifey again, I'll be a busy fella with this and the servo kit. I have a buddy down the road a bit with a two-post lift that should make it all easier though.

I also have a buddy (my best friend who is a Toyota service writer) that's building a 30'x50' with a lift in it that's .3 miles from my house. Yay for me! FREE LIFT!!!

Sounds like good friends to have.

So do I just tell them I have the 145 amp alt. and the v8 and they will figure out the length?
