Kozlira Serpentine Belt Drive Kit for Toyota/Lexus V8 4.6/5.7L — Tensioner, Idler & 8-Rib Belt (2007–2018)

Kozlira's serpentine belt drive kit is a complete replacement assembly — tensioner, idler pulley and 8-rib belt — made to restore proper drive accessory operation on 4.6L and 5.7L V8 Toyota and Lexus models from 2007–2018.

This all-in-one kit supplies the three most commonly replaced components that keep the engine's accessory drive running smoothly: a matched drive belt, a spring-loaded tensioner and a precision idler pulley. Each part is specified to fit Toyota Sequoia, Tundra and Land Cruiser V8s and Lexus GX460/LX570 models listed, and is built for corrosion resistance, temperature tolerance and reduced vibration to extend service life.

What comes in the Kozlira serpentine drive kit?

This kit includes the three parts most often replaced together during accessory drive service: the automatic tensioner, an idler pulley and an 8-rib V-belt. Parts are matched and supplied ready for immediate installation or staging for a scheduled service.

• 1 x Drive belt tensioner (multiple OEM cross-reference numbers included).
• 1 x Idler pulley matching OEM 36370 and related numbers.
• 1 x V-ribbed belt (8PK2415 and equivalent references included).

How does this kit improve drive performance and longevity?

Replacing worn belts, pulleys and tensioners reduces slip, vibration and accessory noise while maintaining proper accessory alignment. Using parts with corrosion and heat resistance helps the system withstand under-hood stresses and preserves belt life.

• Tensioner maintains correct belt tension to reduce slip and premature wear.
• Idler pulley improves belt routing stability and lowers vibration/noise.
• Durable belt material resists cracking and heat-related degradation.
• Matched components minimize mismatch issues from piecemeal replacements.

What should I expect during installation and maintenance?

Installation follows standard accessory drive procedures and typically requires basic hand tools and a tensioner release tool. When replacing these parts, inspect alternator, A/C compressor and power steering pulleys for wear and replace the belt routing if any accessory shows damage.

• Use a tensioner tool to safely relieve and reposition the belt.
• Verify belt alignment and proper seating on all pulleys after install.
• Inspect accessories and mounts; replace any worn bearings or seals.
• Follow OEM torque specs for tensioner and pulley fasteners.
