Product Details
The factory radiator found in the VW/Audi 2.0T TSI application was engineered to only support stock power outputs and last within a set service life. All too often when more power is demanded the cooling system becomes stressed and can shed only so much heat, in so much time. The ECS Tuning in-house engineered Performance Aluminum Radiator utilizes a larger volume, dual row, dual-pass aluminum heat exchanger that is hand TIG-welded to 5052 aluminum end tanks and polished to perfection. Featuring a 20% increase in overall volume compared to stock, this is a direct replacement radiator that will outperform and outlast the OE unit!
PART DESIGN
Our radiator utilizes all factory mounts, fan shroud, hose connections and CBFA-specific PremAir® Sensor for a direct OE upgrade WITHOUT modifications to any other components
Increase in +20% volume over the stock radiator. ECS Radiator measures 2.395 Liters internal volume compared to the OEM Radiator at 1.920 Liters
Larger volume, dual row, dual-pass aluminum heat exchanger
Pressure tested to 1.5 bar at 0% leak down to ensure quality and leak-proof manufacturing
Fabricated 5052 aluminum end tanks

Please note that installation accessories are not included. Please see our full installation kit (ES4030589) with this radiator, for a complete package.
Due to vibrations, we recommend a few drops of medium-strength thread locking compound to be applied to the radiator fan shroud mounting screws. For your convenience, we've included a small tube for this purpose.
