Upgrade or replace your Golf Mk6 cooling system with confidence using the Leak-Proof Plastic Coolant Expansion Tank. Designed to precisely fit Audi A3/TT and VW Golf/Jetta/Passat/Tiguan models, this tank replaces OEM 1K0121407A with a robust, long-lasting solution. Made from thickened PP plastic, it stands up to high temperatures, resists corrosion and cracking, and maintains reliable coolant circulation under demanding conditions.

With precision-molded connections, it ensures tight seals and smooth coolant flow, helping your engine run at optimal temperatures and protecting your powertrain from overheating.
