Coolant Flange – 06A 121 132AQ (VAICO)

Description

Product Description

The 06A121132AQ Coolant Flange by VAICO is an OE‑quality replacement used on select Volkswagen and Audi 4‑cylinder applications. This multi‑port coolant flange mounts to the engine and provides properly aligned connection points for multiple coolant hoses, helping distribute coolant between the engine, radiator, and heater circuit to maintain stable operating temperature.

Coolant flanges are a common leak source as they age. Constant heat cycling and cooling system pressure can cause the original plastic housing to become brittle, warp, or crack—leading to coolant seepage, dried coolant residue, low‑coolant warnings, and potential overheating. Replacing the worn unit with VAICO 06A121132AQ restores a tight seal and dependable coolant flow.
