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 andContinental 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".
Set the screws aside in a safe place.
Set the screw aside in a safe place.
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.
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!
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 theGates K060790serpentinebelt 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.
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.
Check the tension on the new belt by twisting the longest length between the alternator and coolant pump.
If the new belt can be twistedmorethan 90 degrees (perpendicular) to itself, the new belt may be too loose and the tensioner assembly may need to be replaced.
Replace the nuts and screws.
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.
