Performance Drive Belt Kit for Toyota RAV4 (2004-2005) 2.4L

Heavy-Duty Serpentine Drive Belt and Tensioner Kit for 2004-2005 Toyota RAV4 (XA20)

What it Does: The Performance Drive Belt Kit replaces the fatigued factory mechanical tensioner and worn serpentine belt on the 2004-2005 Toyota RAV4 to eliminate accessory belt slip, damp rotational vibrations, and maintain steady charging and cooling performance.

The Stock Toyota RAV4 Belt Drive Weakness

On high-mileage XA20 platforms powered by the 2AZ-FE 2.4L engine, the factory hydraulic/mechanical tensioner assembly is prone to internal spring fatigue and fluid leakage. Over repeated thermal cycles, lost tension induces excessive belt flutter and rib glazing. This slop causes charging system drops under electrical load, poor A/C compressor engagement, and severe high-frequency chatter that accelerates wear across alternator and water pump drive bearings.

The Engineering Solution

This comprehensive service kit replaces critical wear items with precision-matched direct-fit components. The replacement tensioner matching OEM reference 166200W110 utilizes an reinforced internal torsion spring and a precision-sealed bearing pulley to resist axial play and dampen crankshaft torsional harmonics. Paired with a heavy-duty EPDM multi-rib belt (OE 7PK1940), this assembly resists rib cracking, compound hardening, and thermal degradation under severe operating loads.

What's Included

• 1x Automatic Belt Tensioner Assembly (Replaces OE 166200W110)
• 1x EPDM 7-Rib Serpentine Belt (Replaces OE 7PK1940)

Frequently Asked Questions & Fitment Warnings

Does this fit the XA20 RAV4?

Yes, this is a direct fit for the 2004-2005 Toyota RAV4 equipped with the 2AZ-FE 2.4L engine. This kit does not fit 2001-2003 RAV4 models equipped with the 2.0L 1AZ-FE engine.

Do I need a special tool to relieve tension during belt installation?

A standard 19mm wrench or dedicated serpentine belt tool is required to rotate the integrated cast hex lug on the tensioner body to relieve spring tension during installation.
