KPALAG Aluminum Radiator Upper Hose Connector for Toyota RAV4 2009-2012 — Direct-Fit Coolant Pipe Adapter with 3 Clamps

KPALAG’s upgraded aluminum radiator upper hose connector is a direct-fit coolant pipe adapter that replaces plastic fittings for Toyota RAV4 models 2009–2012 (replace #: 16571-0V020 / 16057-36011), offering improved durability and leak resistance.

This precision-machined adapter swaps in for worn or brittle OEM plastic inlet connectors to restore reliable coolant flow and reduce the chance of hose separation or coolant seepage. Made from corrosion-resistant aluminum, the connector includes 3 clamps and is intended to be a straightforward maintenance part for owners or mechanics working on RAV4 2009, 2010, 2011 and 2012 vehicles.

How will this aluminum connector improve my cooling system?

Replacing a cracked or softened plastic inlet with an aluminum adapter reduces the risk of sudden failure and provides steadier hose clamping under heat cycles. Aluminum resists aging from coolant and engine bay temperatures better than many plastics used in original fittings.

• Higher material strength and reduced brittle-failure risk
• Improved sealing under repeated thermal expansion
• Corrosion-resistant surface for longer service life
• Includes three clamps to secure hoses reliably

Is this part compatible with my Toyota RAV4 and the listed OEM numbers?

This coolant pipe adapter is made to match the fit and function of the factory inlet connectors for Toyota RAV4 model years 2009 through 2012. It is supplied to replace part numbers 16571-0V020 and 16057-36011 (and equivalent numeric variants).

• Confirmed fit for Toyota RAV4 2009, 2010, 2011, 2012
• Designed as a direct replacement for the listed OEM numbers
• Check hose diameters and mounting points before installation

How difficult is installation, and what comes in the package?

Installation is intended to be straightforward for anyone comfortable with basic coolant system work: drain the coolant, remove the old connector, swap in the adapter, clamp hoses, refill and bleed the system. The product comes ready with all necessary clamps to secure both hoses for most standard repairs.

• Supplied with 1 radiator upper hose connector adapter
• Includes 3 hose clamps to secure connections
• Basic hand tools and coolant capture tools required
• Follow vehicle-specific bleed procedure after installation

Will this adapter prevent leaks and overheating?

The aluminum connector improves sealing reliability where the original plastic part has degraded, helping to prevent coolant loss that can lead to overheating. While no single part guarantees system-wide performance, replacing a compromised inlet connector removes a common failure point and supports consistent coolant circulation.

• Provides a firmer hose grip to reduce seepage
• Resists deformation under heat for stable flow
• Helps maintain proper coolant levels when installed correctly

Who is this for: This KPALAG aluminum radiator upper hose connector is aimed at Toyota RAV4 owners and independent mechanics who need a durable, cost-effective replacement for brittle or leaking OEM plastic inlet fittings on 2009–2012 models. It suits DIYers with basic workshop skills and professional shops seeking a longer-lasting alternative to stock plastic connectors. Always confirm OEM number compatibility and follow proper coolant system service procedures when installing.
