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!
