How does this part improve my vehicle’s belt performance?

Replacing a worn tensioner pulley removes slack and misalignment that cause belt vibration, noise, and premature wear. The X AUTOHAUX unit functions as a locked-center tensioner or idler-style pulley depending on your vehicle’s accessory layout, helping the belt drive systems operate quietly and reliably.

• Re-establishes correct belt tension to reduce slipping and squeal
• Eliminates pulley-bearing noise from worn original parts
• Stabilizes accessory-driven components like alternator and A/C compressor

What materials and construction features are included?

This assembly is made from metal components chosen for durability under engine-bay conditions. The construction is intended to match the original part’s form and function so fitment and service life are comparable to the factory unit.

• Metal housing and pulley for strength and heat resistance
• Precision bearings to maintain consistent rotation and minimal noise
• Manufactured to align with OE dimensional references for direct replacement

What should I check before buying and installing?

Confirming correct vehicle year, engine size, and the OE part number is essential to ensure compatibility. Basic inspection of belt condition and related components will help you decide whether to replace the belt and tensioner together for best results.

• Verify make, model, year, and engine displacement match listed fitment
• Confirm the OEM numbers 31170-RCAA01 / 31170RV0A01 correspond to your factory part
• Consider replacing the drive belt and inspecting idlers during installation
