Coolant Hose Flange – 06D 121 132C (OE)

Description

Product Description

The 06D121132C Coolant Hose Flange (OE) is a genuine‑spec replacement component used on select Volkswagen and Audi applications. This coolant flange acts as a key connection point in the engine cooling system, providing secure hose interfaces and correct coolant routing between the engine, radiator, and heater circuit (depending on the specific engine layout).

Because it operates under constant heat cycling and system pressure, the original plastic coolant flange can become brittle over time. Cracks, warped sealing surfaces, or leaks at the hose connections can lead to coolant seepage, low‑coolant warnings, and potential overheating. Replacing the worn unit with an OE‑quality 06D121132C restores proper sealing and dependable cooling system performance.

• OEM reference: 06D 121 132C
• OE‑quality fit and sealing performance
• Molded multi‑port design for proper coolant distribution and hose alignment
• Heat‑ and coolant‑resistant composite construction
• Designed to provide secure, leak‑free hose connections under pressure
• Direct‑fit replacement; no modifications required

Applications

Used on select VW/Audi models that specify coolant flange/adapter part number 06D121132C.

(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 and hose clamps during installation for best results.
• Refill with the correct VW/Audi‑approved coolant and properly bleed the cooling system after service.
• Inspect nearby hoses and plastic fittings; replacing aging components together can help prevent repeat leaks.
