Got a loud squealing noise when you start the engine and maybe continuing on even after it has warmed up? Then this is for you.
With the engine off of course, reach down to the serpentine belt on the passenger side of the engine and see how much you can twist it with your fingers. If it's 90 degrees or more, then you need to tighten it. Read on. It only takes 5 minutes.
The good news is that you can do this just reaching in with the hood open, using a 14mm socket and ratchet. Locate the smooth idler pulley (right in the middle on top). Loosen the bolt in the center of the pulley, then under the pulley, turn the other 14mm bolt clockwise to tighten. Re-tighten the bolt in the center of the pulley. The belt shouldn't be able to be twisted quite 90 degrees with your fingers, when it's tight enough.
