Continental 49807 Accessory Drive Belt Tensioner Assembly - Accessory Drive

Continental Multi-V Tensioner Assembly

Continental 49807 is an accessory drive belt tensioner assembly built for OE-style fit and performance. It uses Accu-Drive technology with a round torsion spring to help control belt vibration, maintain steady tension, and keep the belt aligned as components wear.

Compatible with Subaru Legacy, Subaru Outback, and Subaru Tribeca accessory drive applications, this Continental Multi-V tensioner assembly supports consistent belt operation in the engine accessory drive system.

Key Features

• Accessory drive belt tensioner assembly for Multi-V belt systems
• Accu-Drive torsion-spring design helps dampen vibration
• Maintains constant belt tension as the belt wears
• Supports belt alignment for smoother accessory drive operation
• Steel pulley with smooth surface
• Non-flanged pulley design with one pulley included
• Continental part number 49807

Product Details

Continental Multi-V 49807 is engineered to meet or exceed OEM fit and performance requirements. The tensioner uses a steel pulley with a 2.76-inch outside diameter, 1.36-inch width, and 0.670-inch bore diameter. Its smooth, non-flanged pulley design is built for accessory drive belt routing where stable tension and alignment are critical. This part cross-references Dayco 89735 for the same application.

For Subaru Legacy, Subaru Outback, and Subaru Tribeca models, the tensioner helps maintain proper belt load across the accessory drive system. That makes Continental 49807 a direct replacement choice when the original tensioner shows wear, noise, or inconsistent belt control.

What It Helps Solve

• Belt squeal or chirping from inconsistent tension
• Accessory drive belt vibration
• Misalignment caused by a worn tensioner assembly
• Reduced belt control as the spring weakens over time
• Premature wear on belt-driven accessory components

Installation Notes and Tips

Fits 2010-2014 Subaru Legacy, Accessory Drive, Multi-V. Fits 2010-2014 Subaru Outback, Accessory Drive, Multi-V. Fits 2008-2014 Subaru Tribeca, Accessory Drive, Multi-V.

Before installation, inspect the belt, pulleys, and related accessory drive components for wear or damage. Confirm pulley alignment and belt routing against the vehicle service information for the specific Subaru Legacy, Subaru Outback, or Subaru Tribeca application. Replace worn belt components together when needed to help restore proper system operation.
