Illustration 5 g06015845Note: Type 1 heat exchangerNote: Do not reuse the old gasket.Note: Heat Exchanger Plate (Y) and Heat Exchanger Plate (Z) are identical. The orientation of the dimple (one dimple) on the heat exchanger plate is critical during the assembly of the heat exchanger plates. Heat Exchanger Plate (Y) and Heat Exchanger Plate (Z) are for the jacket water in the heat exchanger.Note: Heat Exchanger Plate (S) and Heat Exchanger Plate (T) are identical. The orientation of the dimples (two dimples) on the heat exchanger plate is critical during the assembly of the heat exchanger plates. Heat Exchanger Plate (S) and Heat Exchanger Plate (T) are for the fuel cooler in the heat exchanger.Note: Heat Exchanger Plate (W) has a notch that is stamped in the heat exchanger plate. The notch identifies the port that is blocked to prevent coolant flow. Heat Exchanger Plate (W) is installed to separate the jacket water from the fuel. The orientation of the notch and dimples (two dimples) on the heat exchanger plate is critical during the assembly of the heat exchanger plates.Note: Heat Exchanger Plate (P) has a notch that is stamped in the heat exchanger plate. The notch identifies the port that is blocked to prevent coolant flow. Heat Exchanger Plate (P) is installed against the front frame. The orientation of the notch and dimples (two dimples) on the heat exchanger plate is critical during the assembly of the heat excha
