CNPAPC Drive Belt Tensioner Assembly with Serpentine Belt — 3.5L V6 Fit (2005–2011), Pre-assembled Kit

CNPAPC 39092 drive belt tensioner assembly with serpentine belt is a direct-fit replacement kit for select 3.5L V6 Honda engines, supplying the tensioner, pulley and a 6PK2135 belt in one package.

This complete tensioner kit is made to restore proper accessory-belt routing and tension on Honda J35 3.5L V6 engines found in certain Odyssey, Accord and Pilot model years. The assembly pairs a pre-assembled tensioner and pulley with a matching serpentine belt so you replace the wearing components together and avoid premature mismatch. Materials and manufacturing focus on long-term resistance to heat and engine contaminants, and the kit ships with a one-year warranty and vendor support.

Which models and engines does this tensioner kit fit?

It is compatible with Honda 3.5L V6 (J35 family) applications across specific years and drivetrains. Confirm your vehicle’s OEM part number and engine code before purchase to ensure a direct fit.

• 2005–2010 Honda Odyssey 3.5L V6 (J35A7, i‑VTEC)
• 2008–2010 Honda Accord 3.5L V6 with damper-on-tensioner

What exactly is included in the package and why replace both parts?

The kit contains the tensioner assembly pre-mounted with its pulley and a 6PK2135 serpentine belt sized for the listed vehicles. Replacing both at once prevents a new belt from wearing prematurely on an aged tensioner and restores correct system tension and alignment.

• 1 tensioner assembly with pulley (pre-assembled)
• 1 serpentine belt, part number 6PK2135
• Manufacturer-backed 1‑year warranty and customer support

How does this tensioner assembly handle engine conditions and longevity?

Materials chosen for the pulley bearings, tensioner spring and belt emphasize resistance to heat, oil and road contaminants to maintain reliable operation in demanding engine bays. Properly installed, the kit is engineered to provide long service life comparable to OEM expectations.

• Durable spring and bearing components to retain tension over time
• High-resistance belt compound suited to V6 accessory loads
• Precision fit to reduce misalignment and serpentine slippage

How simple is installation and what should I check during replacement?

Installation is a straightforward job for a home mechanic with basic tools or a technician; the tensioner mounts to the front cover and the belt routes over the accessory pulleys per the factory diagram. Inspect accessory pulleys, AC compressor and alternator for free play during replacement and verify belt routing and tension after installation.

• Use proper belt routing diagram and torque specs for mounting bolts
• Check all accessory pulleys for bearing noise or play
• Verify belt alignment and run engine briefly to confirm tension

Who is this for: This CNPAPC tensioner and belt kit is intended for owners and mechanics servicing 3.5L J35 Honda V6 vehicles listed above who want a single, matched replacement to restore accessory drive function. It suits DIYers replacing worn belts/tensioners and shops seeking a cost-effective aftermarket direct-fit option backed by a one-year warranty and responsive customer support.
