Hey all,

Just rebuilt my double idler pulley, now my main belt squeaks for about 25 seconds on startup, then quiets down. Any idea what could cause that? Should I replace the drive belt?

Thanks

yes

funny this came up. I replaced all of my pullies with UPD pullies and both new belts and after 6 months or so I now have squeel at startup. Super frustrating. I'm going to actually pull the belts this weekend and check the pullies individually.

Yeah I think pulley alignment can cause it too.

So what do you do to fix it? Re installthe pulleys?

New belt fixed the squeal, the old was cracked and had a couple chunks missing. That said, changing that belt is not fun. Very little room to work.

Wow how did a 6 month old belt get so bad so quickly?

I fought this like crazy. Come to find out, all upd pulleys must have snap ring facing forward. I kept replacing belts and everything else. All started when alternator failed. I mistakenly put one of the double roll pulleys backwards.

My belt was the one replaced less than 6 months ago. It is still in perfect condition. The OP did not mention belt age prior.

Not sure where you got that my belt was 6 mo old, it looked original. I have all factory pulleys, btw. Except for the one I rebuilt, it has a dayco composite pulley behind the OEM metal one. The old one shattered when I dropped it, so it definitely needed some love.

As an aside, I did my S/C belt a couple months back, it still looks good.
