This automotive maintenance tutorial was specifically written to assist owners of the second generation (2017, 2018, 2019, 2020, 2021 and revised 2022) Jeep Compass SUV in changing the serpentine accessory belt on the Tigershark MultiAir II 2.4 liter inline four cylinder engine.

Owners of other Jeep, Dodge and RAM vehicles such as the Grand Cherokee, Wrangler, Renegade, Gladiator, Cherokee, Grand Wagoneer, Wagoneer, Charger, Challenger, Durango, RAM 1500, Promaster, 2500 and 3500 may also find these DIY instructions to be helpful.

A few compatible replacement belts with their part numbers include the following: Gates K060790, Goodyear 1060790, ACDelco 6K790, Dayco 5060790 and Continental 4060790.

The tools needed to complete this procedure include a flathead screwdriver, a Phillips head screwdriver, an 8mm socket, a 10mm socket, a 1/4" drive ratchet, a 16mm socket and a 3/8" drive ratchet or a 16mm wrench.

The first few steps are to drive the SUV on to a level surface, shift the gear selector into "Park", turn the steering wheel all the way to the right and turn off the ignition.

It would also be a good idea to engage the emergency / parking brake and place wheel chocks on both sides of the rear tires to help prevent the SUV from moving.

Turning the front wheels all the way to the right will help create more working room in the front passenger side wheel well to access the belt and pulleys.

Next, open the hood and take a moment to look at how the old OEM belt is routed around the various pulleys from above the engine bay.

Then move to the front passenger wheel well and locate the black plastic liner or "splash guard".

Remove the screws at the front of the wheel well liner by turning them in the counterclockwise direction with the 8mm socket and a 1/4" drive ratchet.

Set the screws aside in a safe place.

Crankshaft Pulley
Pull off the wheel well liner or just lift up the bottom edge to access the pulleys and the old serpentine belt.

Take a moment to study how the old belt is routed around the various pulleys including the crankshaft, coolant pump, tensioner, idler, alternator and A/C compressor.

I included a picture of the Tigershark MultiAir 2.4L I4 engine with the pulleys labeled to use as a belt routing diagram.

Locate the tensionser pulley situated above the crankshaft and behind the alternator.

Tensioner Pulley

Rotate Wrench Forward
Place the 16mm wrench or a 16mm socket with a 3/8" or 1/2" drive ratchet over the bolt head in the center of the tensioner pulley.

Firmly and carefully rotate the bottom of the wrench forward towards the front of the car to release the tension on the old belt.

Very carefully slip the old belt off the pulleys.

Warning: Do NOT place your fingers or hands in between the old belt and any of the pulleys!

Route New Pulley
Remove the old belt from the passenger side of the engine bay.

Inspect the old serpentine belt and look for chunks of missing rubber, fraying or metal cables.

If the old belt is in decent condition, consider saving it in your cargo area or garage as an emergency backup just in case the new belt fails prematurely.

I recommend buying the Gates K060790 serpentine belt since it has excellent reviews on Amazon.

Lower the new belt down in to the passenger side of the engine bay.

Route the new belt around the various pulleys.

Keep in mind that the ribbed side of the belt should be wrapped around the ribbed pulleys and the smooth side of the new belt should be against the smooth idler pulley.

Refer to the belt routing diagram above for guidance.

I started by wrapping the bottom of the belt around the crankshaft pulley, then forward to around the A/C compressor, up around the idler pulley, up to over the alternator pulley and then across to the coolant pump pulley.

Then hold the final loop of the belt near the tensioner pulley.

New Belt Installed
Place the 16mm wrench over the bolt head on the tensionser assembly pulley and rotate it counterclockwise (move the wrench handle towards the front of the SUV).

Hold the tensioner assembly rotated back towards the rear of the SUV with one hand and use the other hand to carefully slip the last loop of the new belt over the tensioner pulley.

Double Check Routing
2017-2022-Jeep-Compass-Serpentine-Accessory-Belt-Replacement-Guide-030
Double check that the new belt is routed properly around the pulleys.

Check the tension on the new belt by twisting the longest length between the alternator and coolant pump.

If the new belt can be twisted more than 90 degrees (perpendicular) to itself, the new belt may be too loose and the tensioner assembly may need to be replaced.

Replace Splash Shield
Once you are certain that the new belt has been routed properly and sits evenly on the pulleys, you can lower the plastic wheel well liner back into place.

Replace the nuts and screws.

Tighten Clockwise

Belt Change Done
Spin in the Phillips head screw and tighten it in the clockwise direction until it is snug.

Double check that the two wheel well liners fasteners are secure.

Start the engine and listen closely for any strange sounds that might indicate a problem such as a seized or loose pulley or an improperly routed belt.

Be sure to record the belt change in your SUV's service records.
