Coolant Hose Connector (Lower Radiator Hose) – 5N0 122 291C (VIKA)

Description

Product Description

The 5N0122291C Coolant Hose Connector by VIKA is an OE‑style replacement fitting used on various Volkswagen and Audi models. Installed in the lower radiator hose circuit, this connector provides a secure, sealed junction between the hose and the radiator or engine coolant outlet, ensuring proper coolant flow from the engine to the radiator.

Over time, the original plastic connector can become brittle from constant heat cycles and exposure to coolant. Cracks, distorted sealing surfaces, or broken hose barbs can develop, leading to coolant leaks, low‑coolant warnings, and potential overheating. Replacing the damaged fitting with this VIKA 5N0122291C connector restores a tight, leak‑free connection and reliable coolant circulation through the lower radiator hose.
