ECS Tuning EA113 High-Performance Water Pump (06F121011)

Like many engines of the same vintage, Volkswagen's EA113 utilizes a timing belt-driven water pump with a plastic impeller. Over time, exposure to piping hot temperatures and chemical-rich antifreeze causes the plastic impeller to degrade, resulting in cracks, warpage, and potentially complete failure. This will inevitably lead to reduced coolant flow, consequently overheating the engine and destroying vital components. What's more, many enthusiasts have found the stock pump to be lacking in performance, often finding the limit of the OE pump in modified applications. While the aftermarket is teeming with cast-aluminum impeller alternatives, a high-flowing, heavy-duty solution has yet to come to market. After months of research, development, prototyping, and testing, we are proud to present an all-new water pump that is the first of its kind: the ECS High-Performance Water Pump for EA113 1.8T and 2.0T FSI/TFSI!

To surpass the flow rate of the OE water pump, our engineers focused on refining the pump's impeller. By optimizing the blade angle, shape, curvature, and width, they were able to extract a sizeable increase in flow over the factory design. For even greater efficiency, the impeller is CNC-machined from lightweight billet aluminum. This provides a drastic reduction in weight compared to cast aluminum alternatives and grants a further boost in flow. Using advanced CFD (Computational Fluid Dynamics) simulations, the final design delivered an average 14% increase in flow compared to stock!

However, with longevity in mind, our engineers didn't stop there. To match the refinement of the impeller, billet aluminum construction was also chosen for the construction of the pump housing. A custom, heavy-duty Viton o-ring was sourced for the pump housing sealing surface, providing increased sealing power, fluid and temperature resistance, as well as durability. A double-row bearing was designed to exceed OEM pump service life, ensuring that this water pump will outlast the competition. 

Whether you're upgrading your high-horsepower FSI build or planning a preventative pump replacement on your daily driver, choose our High-Performance Water Pump for increased cooling and reliability!
