IRIEQU Drive Belt Kit for Jeep Wrangler 3.6L V6 (2012–2018) — Complete Kit with Tensioner & Idler Pulleys

IRIEQU Drive Belt Kit with Belt Tensioner and Idler Pulleys is a complete replacement set engineered to restore proper belt routing and tension on 3.6L V6 Jeep Wrangler models from 2012–2018.

If your Jeep Wrangler shows signs of belt wear, squealing, or accessory performance issues, a fresh drive belt kit can be the most efficient way to get the front-end accessory drive back to reliable operation. This kit replaces factory part numbers 4627038AA, 4627038AA-KIT, and 4627038AAKIT and includes a precision tensioner and idler pulleys manufactured to meet OE-style tolerances.

How does this kit restore belt performance?

The kit supplies a new serpentine belt together with the belt tensioner and idler pulleys that control belt routing and tension. Worn pulleys or a weakened tensioner allow belt slip, noise, and premature belt failure, so replacing all related components at once ensures even wear and proper alignment.

• Includes belt, tensioner, and idler pulleys matched to factory fitment
• Tensioner calibrated to maintain correct belt preload
• Idlers machined to reduce wobble and misalignment
• Sold as a complete kit to prevent repeated disassembly

Which Jeep models and years will this fit?

This kit is built specifically for Jeep Wrangler models equipped with the 3.6L V6 engine covering model years 2012 through 2017, plus the 2018 Wrangler JK with the same engine. Always verify your VIN and current part numbers before ordering to confirm exact compatibility.

• Compatible with 2012–2017 Jeep Wrangler 3.6L V6
• Compatible with 2018 Jeep Wrangler JK 3.6L V6
• Replaces part numbers 4627038AA, 4627038AA-KIT, 4627038AAKIT
• Check OEM part reference in your owner’s manual or service records

What are the build and quality specifics of the components?

IRIEQU manufactures the kit using modern production equipment and subjects each part to quality checks intended to match OE form, fit, and function. Bearings are pre-lubricated and housings are finished to minimize friction and extend service life when installed correctly.

• Components produced to strict OE-style tolerances
• Pulleys balanced and bearings pre-filled for smoother rotation
• Tensioner spring and arm tested to targeted preload ranges
• Delivered after multi-point inspection to reduce early failures

How should I install and maintain the kit for longest life?

Professional installation is recommended to ensure correct torque and alignment, but a competent DIYer with the right tools can perform the swap. After installation, inspect belt routing and pulley alignment periodically and replace the belt when cracks, glazing, or rib separation appear.

• Follow factory torque specs for pulley bolts and tensioner fasteners
• Verify belt routing matches the engine diagram before start-up
• Recheck tension and pulley alignment after initial engine run-in
• Replace the entire kit again if any component shows wear within service intervals

Who is this for: This IRIEQU Drive Belt Kit is intended for Jeep Wrangler owners and technicians who need a direct-fit replacement for the 3.6L V6 accessory drive components from 2012–2018. It’s ideal when the original belt, idler pulleys, or tensioner are worn, noisy, or causing accessory drive problems, and for anyone who prefers replacing all related parts at once to avoid repeat labor.
