Aluminum Coolant Hose Flange – 06K 121 132J (BG)

Description

Product Description

The 06K121132J Coolant Hose Flange is an OE‑style replacement component used on select Volkswagen and Audi applications. This flange/adapter provides a sealed connection point in the cooling system, allowing coolant hoses to attach securely while maintaining proper coolant flow and system pressure. A reliable seal here is critical for stable engine operating temperature and consistent heater performance.

Cooling system flanges and adapters are exposed to constant heat cycling, vibration, and pressurized coolant. Over time, sealing surfaces can wear and housings can crack or distort—leading to coolant seepage, low‑coolant warnings, and potential overheating. Replacing the worn part with a new 06K121132J helps restore leak‑free operation and dependable cooling system performance.

• OEM reference: 06K 121 132J
• OE‑style design for correct fit, mounting alignment, and hose routing
• Durable construction designed to withstand heat and cooling system pressure
• Precision sealing surfaces to help prevent coolant leaks
• Direct‑fit replacement; no modifications required

Applications

Used on select VW/Audi models that specify coolant hose flange/adapter part number 06K121132J.

(Fitment varies by engine code and model year—confirm by VIN or parts catalog and match the hose/port layout.)

Service Notes

• Replace any associated O‑rings/seals during installation for a long‑lasting, leak‑free repair.
