Belt routing

Before you remove the old belt, take a clear photo of the belt routing to use as a reference. The routing is as follows:

2.4L MultiAir engine

Starting from the crankshaft pulley at the bottom, the belt goes up and around the A/C compressor, down to the idler pulley, up to the alternator, over to the power steering pump, down to the water pump, and finally to the tensioner.

3.2L V6 engine

Starting from the crankshaft pulley at the bottom, the belt goes up to the A/C compressor, down to the idler pulley, up to the alternator, over to the power steering pump, down to the water pump, and finally to the tensioner.

How to replace the serpentine belt

To replace the belt, you will need a serpentine belt tool or a 3/8" breaker bar. Locate the auto-tensioner and rotate it to release the tension on the belt. While holding the tensioner, slip the belt off of one of the pulleys. Slowly release the tensioner.

After removing the old belt, route the new belt around the pulleys, following your photo or the diagram above. The last pulley to loop the belt over should be the idler pulley or water pump, as they are smooth and will make it easier to slide the belt on.

With the belt in place, rotate the tensioner again and slip the belt over the final pulley. Check that the belt is correctly seated in the grooves of all the pulleys, then slowly release the tensioner.

Replacement interval

We recommend inspecting the serpentine belt at every oil change and replacing it every 60,000 to 90,000 miles, or as needed.

Signs of a failing belt or tensioner

• Squealing or chirping sounds: This is the most common sign of a worn belt.
• Visible wear: Look for cracks, fraying, or missing ribs on the belt.
• Tensioner noise: A bad tensioner can cause a rattling or grinding sound.
• Tensioner pulley wobble: The tensioner pulley should spin freely without any wobble.
