URO 1K0122447AG Engine Coolant Reservoir Overflow Hose

The URO 1K0122447AG Engine Coolant Reservoir Hose is a quality aftermarket replacement overflow hose engineered for Volkswagen vehicles equipped with the 2.5L engine. This hose serves as the critical link between the coolant expansion tank and the engine cooling system, routing coolant back to the overflow or recovery bottle in a closed-loop cooling system to maintain proper operating temperature and prevent overheating.

Manufactured by URO Parts, a brand of A.P.A. Industries, this hose is precision-molded to match the original equipment shape for straightforward, hassle-free installation. It is built from durable EPDM rubber that resists the electrochemical degradation (ECD) that commonly causes OEM hoses to deteriorate from the inside out over time. The material is also engineered to withstand engine heat, ozone exposure, and the vibration inherent in normal cooling system operation.

Key Features:

• Direct-fit replacement — precision-molded to OE recovery tank hose specifications
• Durable EPDM construction — resistant to ECD (Electro Chemical Degradation), heat, and ozone
• Connects the coolant expansion tank to the cooling system in a closed-loop circuit
• Rated for temperatures from -40°F to 275°F (-40°C to 135°C)
• Meets or exceeds OEM specifications for fit and performance
• Ideal for both professional technicians and DIY repair
• OEM Reference: 1K0-122-447-AG

A failing coolant reservoir hose can result in coolant leaks, visible hose cracking or splitting, and engine overheating. Replacing a worn or damaged hose promptly with a quality part like the URO 1K0122447AG helps protect the engine and restore reliable cooling system performance.
