A-Premium Serpentine Belt Drive Kit with Tensioner for 2.4L DOHC (Acura TLX 2015–2020) — Belt + Automatic Tensioner

The A-Premium Engine Serpentine Belt Drive Kit with Tensioner is a complete replacement kit—serpentine belt plus tensioner—designed to restore reliable accessory drive operation on compatible 2.4L DOHC Acura and Honda engines.

This kit brings together the belt and the automatic tensioner in one package so you can address common wear points on the front of the engine at once. It fits specific DOHC 2.4L applications—Acura TLX (2015–2020) and selected Honda Accord and CR-V model years—so you replace both parts that work together to drive alternator, water pump, power steering (where applicable), and other front-end accessories. A-Premium includes a one-year unlimited-mileage warranty covering manufacturing defects for confidence at installation.

Will this kit fit my car’s 2.4L DOHC engine?

Compatibility depends on engine type and model year. The kit is engineered for DOHC 2.4L engines in specified Acura and Honda models; it will not fit engines other than DOHC 2.4L without verification.

• Compatible: Acura TLX 2015–2020 L4 2.4L (DOHC)
• Compatible: Honda Accord 2013–2017 L4 2.4L (DOHC)
• Compatible: Honda CR-V 2017–2019 L4 2.4L (DOHC)
• Important: Confirm vehicle details in the listing selector and check Special Notes before ordering

What parts are included and why replace them together?

This kit contains the serpentine belt and the belt tensioner—two interdependent components that experience similar wear patterns. Replacing both at the same time prevents premature failure of the new belt due to an aging tensioner and reduces the chance of repeat service.

• Included: 1x serpentine belt sized for the listed 2.4L applications
• Included: 1x automatic belt tensioner pre-assembled
• Benefit: Simultaneous replacement cuts labor and helps ensure correct belt alignment
• Outcome: Reduced risk of accessory drive slippage, noise, and uneven wear

How does the tensioner in this kit affect engine performance?

The tensioner keeps correct belt tension across pulleys so accessories run smoothly. Proper tension lowers belt noise and slippage, preserves accessory component life, and supports consistent accessory operation under varied engine loads.

• Function: Maintains steady tension to optimize belt grip on pulleys
• Result: Lower transmission resistance and quieter operation
• Advantage: Helps accessories like the alternator and water pump operate reliably

What warranty and quality assurances come with this A-Premium kit?

A-Premium backs this serpentine belt drive kit with a one-year, unlimited-mileage guarantee against manufacturing defects. That warranty aims to give installers and owners assurance during the first year of use and reflects A-Premium’s focus on aftermarket reliability.

• Coverage: One-year unlimited-mileage manufacturer warranty
• Support: Contact A-Premium for warranty claims and fitment questions
• Recommendation: Inspect pulleys and related accessories at installation for best results

Who is this for? This kit is intended for owners, mechanics, and DIY technicians who need a matched belt-and-tensioner replacement for DOHC 2.4L Acura TLX (2015–2020) or Honda Accord (2013–2017) and CR-V (2017–2019) engines. Choose this kit when the old belt shows cracking, glazing, or wear, or if the tensioner exhibits noise, loss of tension, or visible damage. If you are unsure about fitment, use the vehicle selector on the product page and review the special notes before purchasing to ensure a correct match for your engine configuration.
