Serpentine Belt, idler pulley and tensioner.
 

Hi, anyone know where online to purchase a serpentine belt, belt tensioner and serpentine belt pulley, it for a 1999 gmc k1500 sierra.
I purchased a kit with all three from 1aauto.com but the tensioner pulley was not the right one for the 5.3L. They said they don't have it.

Can’t seem to find a kit with all three for the 5.3L.

Any help is appreciated. :)

Have you tried using rockauto.com?

I looked at most i googled, they don't seem to list for a 5.3L though.

Try looking for a 2000 silverado, they changed body styles in 1998, and as far as I know, 1999 model year trucks were harder to get parts for because you could also get an old bodystyle truck of that year too.

Just to ask, is there a reason you can't go to a NAPA or Advance Auto? Also, both, and Autozone, have online stores. Don't know if they ship to the house or if it has to come to a store. Any of the major auto parts chains should have everything you need for a 5.3L.
