Coolant Hose Adapter – N 906 929 01 (OE)

Description

Product Description

The N 906 929 01 Coolant Hose T-Connector is an OE-style replacement fitting used on various Volkswagen and Audi vehicles. This 3-way “T” junction is a critical component of the engine cooling circuit, allowing for the branching of coolant flow between the radiator, engine block, and heater core or expansion tank. It ensures that coolant is distributed correctly to maintain stable operating temperatures throughout the system.

Over time, the original plastic connector is subjected to constant heat cycles, pressure, and vibration, which can cause the material to become brittle. This often leads to hairline cracks or complete failure at the hose barbs, resulting in sudden coolant loss, low-coolant warnings, and potential engine overheating. Replacing a weakened or leaking connector with this OE-quality N 906 929 01 fitting restores a secure, leak-free junction and reliable cooling system performance.

• OEM reference: N 906 929 01
• OE-style T-connector engineered for precise fit and correct hose alignment
• Durable, heat-resistant plastic construction designed to withstand cooling system pressure
• Precision-molded barbs ensure a secure, leak-free grip for attached coolant hoses
• Direct-fit replacement; no modifications required to the factory cooling lines
• Helps prevent coolant loss and protects the engine from overheating

Applications

Used on select Volkswagen and Audi models that specify coolant hose T-connector part number N 906 929 01. Fitment varies by engine code and model year; please confirm compatibility via VIN or parts catalog to ensure this matches your specific cooling system layout.

Service Notes

• It is highly recommended to use new hose clamps during installation to ensure a long-lasting, leak-free seal.
• Inspect the ends of the connected hoses for swelling or internal damage; replacing aged hoses at the same time can prevent future failures.
• Refill the system with the correct VW/Audi-approved coolant and properly bleed the air from the cooling system after service.
