Serpentine belts break from wear, turning the steering wheel to far to the right or left all of the time (if you do this, you know the squeeling I'm referring to), Or Idler and tensioner pulleys in need of replacement.

It is most likely the failure of the idler pulley but replace both the idler and tensioner when replacing the belt

What can I do to fix a pulley for my serpentine belt that has stopped rotating?


These pulleys have sealed bearings but they don't last forever. Buy a new one and replace it before you break your serpentine belt.

Serpentine belt keeps breaking


whichever pulley it is sliding off of is not straight. check the alignment of ALL the pulleys and make sure there is no play in them. They should all be solid with no wobble. My guess would be a bearing is bad allowing play in the pulley which lets the belt "walk" to the edge.

My engine was screeching and then it would stop it got progressively worse then the fan belt broke how do I replace it do I have to remove the other belts


Okay, those type belts don't just break. The screaching you were hearing was one the pulleys locking up, and in doing so makes the belt get very hot. Once it gets hot enough to melt the rubber in it, it will come apart. I recommend you inspect all the pulleys, and make sure they spin freely, and NO grinding noise.

I suspect either the idler pulley, or the tensioner pulley.

How do i change the timing belt in a 2003 mitsubishi lancer es


Hi, first pop the hood and find the serpentine and alternator belts on the left side of the engine compartment. The serpentine belt runs around four pulleys. The alternator belt uses two pulleys. They share space on the drive shaft so they are right next to each other.
Of the four pulleys using the serpentine belt, three of them are vertically in line (closer to the front of the car) and the fourth stands alone (closer to the cab). Of the three vertically in line, the middle pulley is the one used to adjust the tension on the belt.
You must first break loose the bolt in the center of the tension pulley (the bolt is facing the passenger tire) by turning it counter clockwise. Then leave that bolt and go to the bolt connected frame connected to the other side of the tension pulley (this bolt is facing the front of the car). Turn that bolt counter clockwise until the serpentine belt is loose enough to pull off. Replace the belt and tighten in the opposite order. Once the desired tension is reached, crank the car and run it for a few minutes. Finally cut the car off and check the tension, tighten or loosen as necessary.
Take care

  1. Disconnect the negative battery cable.
  2. Rotate the auto tensioner clockwise to release tension, then remove the drive belt.
To install:
  1. Install drive belt (A). Route the belt over the components in the following order: Crankshaft pulley → A/C pulley → idler pulley → generator pulley → water pump pulley → P/S pump pulley → tensioner pulley.
  2. Rotate auto tensioner arm in the counter-clockwise moving auto tensioner pulley bolt with wrench.
  3. After putting belt on auto tensioner pulley, release the auto tensioner pulley slowly.

Burning rubber smelll under hood of 1999 nissan quest


Check your serpentine belt. May have bearings out on a pulley on a component within the serpentine path. If the pulley locks, the belt is forced over it causing the burnt rubber smell.
