Coolant Hose Connector – 1J0 122 291B (OE)

Description

Product Description

The 1J0122291B Coolant Hose Connector is an OE‑style replacement fitting used on select Volkswagen and Audi applications. This connector provides a secure junction point in the engine cooling system, allowing coolant hoses to connect tightly and route coolant correctly between cooling system components to maintain proper operating temperature and system pressure.

As these plastic connectors age, repeated heat cycles and coolant exposure can make them brittle. Cracking, warped sealing surfaces, or weakened hose connections can lead to coolant seepage, low‑coolant warnings, and potential overheating. Replacing the failed connector with a new 1J0122291B restores a leak‑free connection and reliable coolant circulation.

• OEM reference: 1J0 122 291B
• OE‑style construction for proper fit and hose alignment
• Heat‑ and coolant‑resistant composite/plastic material
• Designed for a secure, leak‑free hose connection under system pressure
• Direct‑fit replacement; no modifications required

Applications

Used on select VW/Audi models that specify coolant hose connector part number 1J0122291B.

(Fitment varies by engine code and model year—confirm by VIN or parts catalog.)

Service Notes

• Replace any related 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.
