Coolant Hose Connector – 5Q0 122 291CT (OE)

Description

Product Description

The 5Q0122291CT 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 coolant hoses and the engine or radiator assembly, ensuring correct coolant routing and leak‑free operation.

Over time, the original plastic connector can become brittle from repeated heat cycles, pressure, and vibration. Hairline cracks, warped sealing surfaces, or weakened hose connections can develop, leading to coolant seepage, low‑coolant warnings, and potential overheating. Replacing the damaged fitting with a new 5Q0122291CT connector restores a tight seal and reliable coolant circulation.

• OEM reference: 5Q0 122 291CT
• 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 engine/radiator outlets
• Compatible with factory‑style O‑rings and hose clamps (where applicable)

Applications

Used on select Volkswagen and Audi models that specify coolant hose connector part number 5Q0122291CT. Fitment varies by engine code and model year; confirm by VIN or parts catalog.

(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 nearby coolant hoses and plastic fittings; replacing aging components together can help prevent future leaks and overheating issues.
