Will hopefully have a video up tomorrow or the day after. Need help determining whether or not to replace the pulley itself on the tensioner and/or the lower idler pulley. My belt wobbles like hell back and forth on the tensioner, but I can't tell if it'* due to the ridges worn on that pulley or the odd wearing of the plastic idler below it. Just at idle it already wore the numbers clean off the belt!

By golly does it feel good to have my whine back.
I feel like a woman

Oh yeah, and the oil appears to be SC oil from it warming up with the engine then just seeping out of the vent in the middle of the pulley. Correct me if I'm wrong on that one. Still has good oil level, could probably use a change or topoff at least.

Enough of this computer stuff, I'm going out driving!

Right. So. My belt is down to 4 of the ridges left. In what, 3 days? I know for a fact I don't drive it that hard.

Smooth idler pulley $16 GM dealer
Tensioner pulley not available

Anybody know if there'* any upgrade for the smooth idler?

I'm sure the 126,000 miles haven't been too kind to the cheapplastic, and that'* why I'm replacing it. It looks warped, and the belt is sliding over the lip on the outside. Annoying as hell to get to to replace, but it'* got to be done. Tensioner pulley has a 2 grooves worn into it, with a ridge offcenter. I doubt that'* having as much of an effect as the plastic hoohah.

Default Problem solved, pictures to come

The new idler is made of metal, not plastic. I'll have a pic of the old pulley up tomorrow so you can see just how not square it is. It'* angled so much it was making the belt jump grooves and eventually throwing the thing completely off.

The replacement of said pulley involved a die grinder and the motor mount. "Modifications" indeed! Will also grab a pic of how my dad "customized" the motor mount instead of taking the whole thing off to get to the idler

This is not something I would have done in the street without some pneumatic tools. Motor mount bolts are a pain in the shoulder. Aside from that, it was a piece of cake and my problem is completely solved

After 200 miles there are still words on the back of my belt! Sure beats 5 mins at idle wearing them off the last one

Side note: The depth of the grooves on my Autozone belt, which was a Goodyear, was only about a 2 on the I don't know what scale I used. The depth on the GM belt was 3. The depth of the grooves on the pulley is between 3 and 4. Probably just worthless info

Yeah, ok, I ended the last 4 paragraphs with smileys. I'm just happy to have my whine back FOR GOOD!
