Coolant Hose Connector – 5Q0 122 291AB

Description

Product Description

The 5Q0122291AB Coolant Hose Connector is an OE‑style replacement fitting used on various late‑model Volkswagen and Audi vehicles. Installed in the engine cooling circuit, this connector provides a secure, sealed junction between radiator and/or heater hoses and the engine or radiator assembly, ensuring proper coolant routing and leak‑free operation.

Over years of service, the original plastic connector is exposed to continuous heat cycles, pressure, and vibration. This can cause the body to become brittle, develop hairline cracks, or distort at the sealing surfaces. Hose barbs may also weaken and break, leading to coolant seepage, low‑coolant warnings, and potential overheating. Replacing the damaged fitting with a new 5Q0122291AB connector restores a tight seal and reliable coolant circulation.

• OE‑style coolant hose connector engineered to match VW/Audi specifications
• Precision‑molded plastic/composite body for correct fit and hose alignment
• Designed to provide a secure, leak‑free junction between coolant hoses and radiator/engine outlets

Applications

Used on select Volkswagen and Audi models that specify coolant hose connector part number 5Q0122291AB.
Exact applications vary by engine and model year; consult a parts catalog for precise fitment.

Always verify compatibility via VIN and by matching the part number and hose configuration on your existing connector before ordering.

Service Notes

• Replace any related O‑rings and hose clamps during installation to ensure a long‑lasting seal.
• Refill with approved VW/Audi G12++/G13 coolant and properly bleed the cooling system after service.
• Inspect adjacent coolant hoses and plastic fittings; replacing aged components together can help prevent future leaks and overheating issues.
