MOCA AUTOPARTS Serpentine Belt 6PK2240 for Jeep Liberty 3.7L (2009–2012) EPDM Ribbed, Direct-Fit

MOCA AUTOPARTS 6PK2240 is a replacement EPDM serpentine belt engineered to restore accessory drive performance on 2009–2012 Jeep Liberty 3.7L engines.

If your Liberty's accessories—alternator, power steering, A/C compressor and water pump—are slipping, squealing, or showing visible wear on the old belt, this direct-fit replacement supplies a cost-effective way to refresh the accessory belt drive system. Constructed from EPDM compound with a ribbed profile, the 6PK2240 matches factory routing and pulley engagement so the engine accessories operate smoothly when installed correctly.

How does this belt match my 2009–2012 Jeep Liberty 3.7L?

The 6PK2240 is sized and rib-profiled to align with the original equipment pulleys on Jeep Liberty models with the 3.7L engine from 2009 through 2012. It cross-references popular OE and aftermarket part numbers to help confirm fitment before purchase.

• Exact nominal length and rib count for direct routing on compatible Liberty 3.7L engines.
• Cross-reference list includes common OE numbers for quick compatibility checks.
• Designed to seat properly in pulley grooves for consistent load transfer.

What materials and design features improve durability?

Made from EPDM (ethylene propylene diene monomer) rubber, the belt offers enhanced resistance to heat, ozone and oil exposure compared with older rubber compounds. Its precision rib profile distributes load evenly across the accessory belt drive system, reducing localized wear and helping accessories run at designed speeds.

• EPDM compound resists cracking and hardening from engine heat and ozone.
• Accurate rib geometry for uniform load transfer and reduced slip.
• Reinforced tensile cord for consistent tension and elongation control.

What should I check during installation and maintenance?

Confirm this belt fits your vehicle by checking vehicle fitment data or the cross-reference part numbers; improper fit can cause noise or premature wear. During installation, inspect pulleys, tensioner, and idlers—worn components will shorten belt life even if the belt itself is new.

• Verify fitment using the vehicle year, engine size and listed part numbers.
• Replace or inspect tensioner and idler bearings for smooth rotation and correct tension.
• Follow factory routing diagram; avoid twisting the belt during installation.

Who is this for? This MOCA AUTOPARTS 6PK2240 belt is intended for DIYers, independent mechanics and fleet technicians who need a reliable, OEM-compatible replacement for Jeep Liberty 3.7L models from 2009–2012. It's suited for anyone replacing a worn or damaged serpentine belt and for use during routine accessory drive maintenance, provided pulleys and tensioners are in good condition. If you need assistance confirming fitment, consult your vehicle's service manual or reach out to the professional-friendly U.S.-based MOCA support team for help resolving fit or installation questions.
