Sounds like the idler pulley that's used to adjust belt tension. They usually fail around 100,000 miles, but the good news is that it's an easy replacement. Just be sure to get a genuine GM part. A parts store brand might only last 25 or 30,000 miles.

Kia sedona engine noisy when cold


Check to see if your fan belt is making that noise. When they get old, sometimes the rubber gets hard, and they make an awful racket.

My serpentine belt broke drove car 30 miles home without belt, got a new belt put it on cranked car up took for test drive got back opened hood realised the exhaust manifold was red hot. Turned A/c off...


  • Well, that belt drives everything including the water pump. When the belt broke and you drove it no coolant circulated and the exhaust glowed from overheating. A red glowing manifold usually only happens from excessive heat caused from modified engines. But in this case this is almost surely what happened. You are lucky you did not blow your engine. Park it and let it cool down for a few hours.

Check the fluid level in the trans. With the engine hot, truck idling in park, make sure the fluid reaches the "HOT" range on the trans dip stick and it is bright red and doesn't smell burnt.
