A: This tensioner comes with limited 12 months / 12,000‑mile warranty, whichever occurs first. The warranty excludes wear‑and‑tear damage, improper installation and external contamination damage.
Q: Do I need to replace the serpentine belt together with this new hydraulic tensioner assembly?
A: It is strongly recommended to swap out your serpentine belt while installing this new tensioner. An aged, stretched old belt will accelerate wear on your brand‑new tensioner unit and lead to noise or slippage issues shortly after repair, especially under off‑road conditions.
Q: What are typical warning signs that my hydraulic belt tensioner needs replacement?
A: Common symptoms include squealing or chirping noise from engine bay especially on cold startup and off‑road vibration, visible pulley wobble, excessive belt slippage, uneven belt edge wear, or fluctuating performance of AC, alternator and power‑steering accessories.

A: Yes, we provide preferential rates for large‑volume commercial purchase orders. For this reason, our dual‑US‑warehouse inventory ensures fast restock and stable supply for busy repair workshops.
Q: Does this tensioner reuse my original factory mounting bolt during installation?
A: Yes, this assembly does not supply mounting bolt. You must reuse your existing factory bolt, please inspect it for thread damage or stretching before reinstallation. Replace bolt if you spot any signs of wear.
Q: Can I only swap out the pulley bearing instead of installing full hydraulic tensioner assembly?
A: It is not recommended to replace pulley bearing alone. Internal hydraulic damper components degrade over time under off‑road vibration. Installing complete assembled unit delivers reliable long‑term repair result for your accessory‑drive system.
