The factory coolant routes out of the engine block, into a Y-piece where it splits into the engine water radiator and then into the DSG cooler. This DSG Cooler is surprisingly small and does not have the size or efficiency to exchange heat before it exits the cooler and routes to the DSG oil/water heat exchanger. If the engine coolant is hot and the DSG oil is hot, which is the case when driving cars with a higher output than stock, spirited or track use, this hot coolant now has little to no cooling effect on the DSG oil and DSG temperatures begin to rise. With a high oil temperature, the DSG is at risk of becoming damaged. To help prevent damage the DSG will begin to lower the torque, increase shift times and in extreme circumstances gears can be lost. In the worst cases, costly damage to the gearbox can be caused. After extensive analysis and development, CSF has created a Quadruple Pass DSG Cooler gives an increased cooling performance over the stock item in a number of areas.

The CSF Quadruple Pass DSG Cooler uses a 2-row 42mm core, this utilizes all of the available space. The B-tube design maximizes the tube efficiency in all areas, this tube design is stronger than standard oval tubes and less material can be used for a lighter more efficient heat transfer whilst surface area inside the tube is increased by 15%.

The Quadruple Pass design allows coolant to pass across the core four times before it exits maximizing the time the radiator has to exchange heat for the coolest outlet temperature.

This unique design results in a flow area increase of 42% and a heat rejection increase of 36%. Helping to keep DSG temperatures consistently cooler for longer. The radiator also comes complete with a removable rock guard for improved longevity against rock hits/debris.Stock Cooler:
