funny that only one comes up if you enter vehicle info and thats the ac belt. but the others do come up if you put the number in the search. ???

 

Yes. When I did it back in March they both came up. Now only the one. But its the same part # that I bought. They are nice belts. Very quiet and well made.

 

Hey Joe, Thanks again for getting the part numbers. I just received my parts from rockauto. But I have a question for you or anyone else who may know. For part# 49154 (main drive belt idler pulley) ,what is this O-ring for? it came in the box, but the instructions make no mention of it. I hope to be able to see where the spacer and washer will once I get the old one off, but I'm stumped as to why I need an O-ring. I haven't taken anything apart in my Tahoe, I will this Friday. I just wanted to get a heads up. Dont want any surprises! =) Thanks in advance!

I think its just supposed to help lock the bolt in place, because of the washer and spacer/retainer thing. I can't remember if mine came with an o-ring...

 

Ok thanks for the quick feedback! I'll just see if there is an o-ring with the stock pulley as well, then decide to use it or not. Thanks again!

Hey Joe, I found it on rockauto's pics of this part. Their website site is awesome!
I guess it just helps hold everything together while you place all pieces in their final place, just as you said! Thanks again for your help friend!

 

AH yes! Thats it! Now I remember the o-ring. Very nice of Good Year to put in for us. Helped out holding it all together lol

 

lol! Yes, it was nice of them! lol. I got the belts changed and both tensioners and the main drive idler pulley. I was kind of nervous doing it, since I'm still a novice, but with the help of youtube videos, I had the confidence to do it. The a/c belt was cracked pretty bad, but the main drive belt was in awesome condition, no cracks at all. I almost felt bad for throwing it out. lol. The idler pulley on the main drive belt still felt and sound fine, but who knows really how much more life it had, I got 163,000 miles out of it, so I'm happy. The a/c tensioner was a little worn, it wiggled quite a bit (the pulley). But the new tensioner also had some slight wiggle to it, but not as bad, maybe thats normal for the part.

If I had to do it again, I would've bought the ac delco idler pulley for the main drive belt, much easier design to deal with, it has a locking washer to hold all of it together. I had to take the goodyear pulley out twice due to the o ring moving, and since you can't really see if its all aligned, but can kind of feel it, I just went ahead and pulled it back off to calm down my OCD. lol.

I love working on my cars, it gives such a great feeling of accomplishment. I know the job was done well, not to mention all the money I've saved doing it myself.

Thanks Joe for your help, and thanks to the youtube people posting how to's that make the job that much easier for me!
