MOCA AUTOPARTS Serpentine Belt Kit for Toyota Avalon 3.5L (2005–2012) — OE-Equivalent Belt, Tensioner & Idlers

MOCA AUTOPARTS serpentine belt kit is a complete replacement set engineered to restore accessory drive performance on 2005–2012 Toyota Avalon 3.5L models.

If your Avalon is due for a belt service, this MOCA kit collects the right serpentine belt and matched components so you can replace the worn parts in one service. The kit contains OE-equivalent belts and related pieces manufactured to precise dimensions and materials so the accessory belt drive transmits power reliably across the alternator, A/C compressor, power steering pump and idlers.

What parts are included and how do they match OEM standards?

The kit groups MOCA parts produced under strict quality controls to meet or exceed original equipment performance. Each component is dimensioned to maintain correct rib alignment and load distribution across the accessory belt drive system.

• Primary serpentine belt sized to OE spec (e.g., 7PK2090)
• Associated idlers, tensioners and mounting pieces matched to Toyota fitment
• Cross-referenced part numbers included: 166040P010, 166040P011, 1660431010, 1660431020, 1662031040, 7PK2090, 36173, 38410, K070822
• Manufactured and inspected to maintain rib profile precision and material durability

How will this kit improve the accessory belt system on my Avalon?

Replacing an aged belt and worn components restores proper tensioning and smooth power transfer, helping accessories run without slip or excess noise. Correct rib profile and dimension control reduce stress on pulleys and bearings.

• Reduces belt squeal and slippage when installed correctly
• Even load distribution prevents premature accessory wear
• Helps maintain factory-aligned belt tracking across pulleys

Is this kit compatible with my Toyota Avalon, and how should I confirm fitment?

This MOCA kit is specified for Toyota Avalon 3.5L model years 2005 through 2012. Always double-check vehicle application before ordering to ensure proper part selection.

• Verify model year and engine size match: Avalon 3.5L, 2005–2012
• Compare listed part numbers with your vehicle’s existing components
• Use MOCA’s fitment information or your VIN to confirm compatibility

What should I expect during installation and maintenance?

Installation requires routine belt service steps: relieve tensioner, remove old belt, inspect pulleys and accessories, then route and tension the new belt per factory routing. If other drive components show wear, replace them together for best results.

• Follow vehicle-specific routing diagram and torque specs for fasteners
• Inspect pulleys, tensioner bearings and idlers for play or damage
• Test-run engine to confirm quiet operation and correct belt tracking

Who is this for? This MOCA AUTOPARTS serpentine belt kit is aimed at DIY enthusiasts, independent shops and fleet mechanics who need an OE-matched replacement for the Toyota Avalon 3.5L (2005–2012). It’s suited for anyone performing preventative maintenance or restoring accessory-drive function after belt-related issues, and for buyers who want clearly listed part numbers and U.S.-based customer support for post-purchase help.
