2000 Chevy Cavalier 4 cyl Two Wheel Drive Automatic 124000 miles
Bad idler pulley--Bearing actually fell apart when I was investigating a noise under the hood. Removed the bolt holding the pulley to the block bracket and got a Dayco replacement. Unfortunately, when all was hooked back up to the serpentine belt, the bolt works its way loose when the pulley spins.
I got a used pulley and bearing assembly at a scrap yard and will install tonight. Should I use Loctite blue on the threads. The threads on the original bolt and this scrapped pulley and bolt are fine as is the female threads on the bracket that accepts the pulley bolt.
Any idea how tight I should crank down on the idler pulley bolt? When I removed bolt and pulley at the scrap yard, it was snug, but not overly tight as I just needed a 8" long wrench and because of its location, you can't get a lot of leverage anyway. I just don't want to bind up the bearing by overtightening, but also don't want the pulley bolt to come loose again, hence the Loctite blue.
