To test if its the belt, while its running , CAREFULLY, you can put a light spray of silicone on the outside of belt first, this will determine if the belt is slipping on the outer side and the idler/tension pullies. Sometimes the coating on the pullies wear and cause a squeak.

Next CAREFULLY spray lightly the rib side of the belt, this can help determine if its the inside ribs that are squeaking.

If squeaking still happens after the silicone spray test, you may have a bearing in one if the pullies going bad. The bearings are replaceable or you can buy the pulley/bearing as one unit.


Belt R&R isn't that hard, some members will pull up on the belt from the top and use the tensioner tab lock to keep the tensioner in the open position. I go from under the truck and use a 1/2" drive ratchet in the tension pulley and pull on the tension with one hand and use my other hand to lock the tab.

Some members will just unbolt the alternator with belt still tight and roll the alternator from the back to the front, then go back to the tensioner and lock the tab.

The tensioner lock tab can be hard to see on the truck, it's marked in yellow in the pic below.

BTW, nice gift for your hubby!! Got any sisters?!? LOL!

P.S.....since the alternator died have the batteries tested individually. They usually go hand in hand. If you find one bad replace them both or another alternator will be in your near future.

thank you, batteries have been checked and charged...truck starts and runs its just the belt that im worried about.. but THANK YOU AS WELL!!!

u can wipe liquid soap on the belt both sides where u can reach ( just put it in your hand and smear it on the belt )

let it dry a bit and fire it up

this will isolate the fact it's a belt and not a pulley bearing ,, it will also be a permanent fix and not slippery so the belt wont slip when say you engage the AC
