Coolant Hose Flange – 06A 121 132AQ (OE)

Description

Product Description

The 06A121132AQ Coolant Hose Flange (OE) is a genuine-spec replacement component used on select Volkswagen and Audi vehicles. This multi-port flange serves as a critical distribution junction in the engine cooling system, providing secure connection points for multiple coolant hoses to ensure proper coolant routing between the engine, radiator, and heater circuit for stable operating temperatures.

Over time, the original plastic flange is subjected to constant heat cycles, pressure, and vibration, which can cause the material to become brittle. This often leads to hairline cracks or warped sealing surfaces, resulting in persistent coolant seepage, low-coolant warnings, and potential engine overheating. Replacing a weakened or leaking flange with this OE-quality 06A121132AQ unit restores a secure, leak-free junction and reliable cooling system performance.

• OEM reference: 06A 121 132AQ
• OE-quality construction for precise fitment and reliable sealing
• Multi-port design engineered for correct coolant distribution and hose alignment
• Durable, heat-resistant composite construction designed to withstand cooling system pressure
• Precision-molded ports ensure a secure, leak-free interface for attached coolant hoses
• Direct-fit replacement; no modifications required to the factory cooling system

Applications

Used on select Volkswagen and Audi models that specify coolant hose flange part number 06A121132AQ. 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 replace the flange O-ring/gasket and any associated sensor seals during installation for a leak-free repair.
• Use new hose clamps to ensure a secure grip on the aging coolant hoses.
• Refill the system with the correct VW/Audi-approved coolant and properly bleed the air from the cooling system after service.
