The Boigevis Transmission Oil Cooler (Part No. 7H0317019B) is tailor-made for the Volkswagen Multivan. The R&D team has conducted in-depth research and testing based on the vehicle's design structure and transmission operating characteristics, ensuring easy installation and precise fitment, which lays a solid foundation for the stable operation of the transmission system. Crafted from high-quality aluminum materials, the product leverages outstanding thermal conductivity to quickly absorb and transfer heat from the transmission, low density for lightweight performance that enhances vehicle fuel efficiency, and excellent corrosion resistance to adapt to complex driving environments. Combined with a carefully designed heat dissipation structure and unique fin layout, it significantly increases the heat dissipation area to achieve efficient convective heat dissipation. Even under extreme working conditions such as long-term high-speed driving or frequent start-stops, it can still maintain the transmission oil temperature within a reasonable range, preventing a drop in transmission oil viscosity and reduced lubrication performance, minimizing gear wear, and ensuring the smooth and efficient operation of the transmission.
