Owners of other Chrysler, Dodge, Jeep and RAM vehicles such as the Town & Country, 200, Pacifica, Avenger, Charger, Journey, Challenger, Dart, Durango, Magnum, Grand Caravan, Grand Cherokee, Renegade, Wrangler, Compass, Liberty, Patriot, ProMaster, 1500 and C/V Tradesman minivan may also find these DIY instructions to be helpful.

A few compatible replacement serpentine accessory belts with their part numbers include the following: Dayco 5060665, Gates K060663, Bando 6PK1685, Roadmax 6K663AP, Mopar 05184647AB and Chrysler 5184647AB.

The tools needed to complete this procedure include a flathead screwdriver, an 8mm socket with a 1/4" drive ratcheting wrench and a 3/8" drive ratcheting wrench with a short extension bar.

Begin by removing the three screws located along the front edge of the engine air box cover by turning them counterclockwise.

You can use either a Phillips head screwdriver, a flathead screwdriver or an 8mm socket with an extension bar and a 1/4" drive ratcheting wrench.

Set the three screws aside in a safe place.

Loosen the metal hose clamp on the left side of the air box cover by turning it counterclockwise with a flathead screwdriver.

Lift the air box cover out of the engine bay and set it aside in a safe place.

Remove the single bolt at the front edge of the lower air box housing by turning it counterclockwise with the 8mm socket and a 1/4" drive ratcheting wrench.

Set the 8mm bolt aside in a safe place.

Loosen the metal hose clamp on the rear of the air intake housing by the air intake manifold by turning it counterclockwise with the flathead screwdriver.

Take a moment to study how the OEM serpentine belt is routed around the alternator, idler, water pump, power steering, A/C (air conditioning) compressor, crankshaft and tensioner pulleys.

Attach the short extension bar to the 3/8" drive ratcheting wrench.

Insert the end of the 3/8" drive extension bar in to the square shaped opening near the end of the tensioner assembly arm.

Firmly rotate the ratcheting wrench in the counterclockwise direction (to the left) in order to release the tension on the old belt.

Continue removing the old belt from the various pulleys and remove it from the engine bay.

Check the idler and tensioner pulleys to make sure that they spin freely and do not wobble or make strange noises. A replacement idler pulley is the ACDelco 38082 and a replacement tensioner pulley is the Gates 38082.

If the tensioner arm was very easy to rotate or the old belt was very loose, consider replacing the tensioner assembly.

Two compatible replacement tensioner assemblies with their part numbers are as follows: ACDelco 39282 and Gates 39282.

Lower the new serpentine belt in to the engine bay.

A good rule to remember is that the ribbed side of the new belt gets wrapped around ribbed pulleys and the smooth part of the pulley goes against the smooth pulleys.

Insert the 3/8" drive extension bar in to the tensioner assembly and rotate it counterclockwise (to the left).

Hold the tensioner down with the wrench with one hand and carefully slip the last belt loop over the ribbed alternator pulley.

Check the tension on the new belt by twisting the longest run. You should only be able to twist the belt to about 90 degrees or perpendicular to the rest of the belt.

Lower the air intake assembly back in to place.

Tighten the air intake hose clamp in the clockwise direction with the flathead screwdriver.

Lower the engine air filter down in to the lower half of the air box.

Line up the three plastic tabs on the rear of the air box cover with the slots on the bottom half of the air box.

Slide the air box cover back in to place.

Tighten the hose clamp in the clockwise direction by turning it clockwise with the flathead screwdriver.

Replace the three screws along the front edge of the air box cover and tighten them in the clockwise direction with the flathead screwdriver or an 8mm socket with an extension bar and a 1/4" drive ratcheting wrench.

Push the plastic engine cover down in to place.

Start the engine and listen closely for any strange sounds that might indicate a problem such as a worn out pulley or a faulty tensioner assembly. If you hear any odd noises, turn off the engine immediately and check the belt routing.
