Illustration 1 g00811028
The cooling system has two pumps that are driven by the engine. Coolant from the jacket water cools the first stage of the aftercooler. The separate circuit cools the second stage.
Illustration 2 g00811012
Cooling system for the jacket water and a separate circuit for the two-stage aftercooler that operates at a standard temperature
Water temperature regulators are used in each circuit in order to maintain correct operating temperatures.Jacket Water System
The jacket water pump is located on the right front side of the engine. The water pump has a gear that is driven by the lower right front gear group. Coolant from the radiator or the heat exchanger enters the water pump's inlet. The rotation of the impeller in the jacket water pump pushes the coolant through the system.The flow of the coolant is divided. Some of the coolant from the jacket water pump flows through a tube to the front of the cylinder block and into the main distribution manifold for the water jacket of each cylinder. The remainder of the coolant flows through the engine oil cooler. After flowing through the engine oil cooler, this portion of the coolant is divided again. Some of the coolant flows into the water jacket of the right rear cylinder. This coolant is mixed throughout the engine's water jacket with the coolant that flows to the front of the cylinder block. The remainder of the coolant flows through the first stage of the aftercooler.The coolant inside the cylinder block flows around the cylinder liners. The water jacket is smaller near the top of the cylinder liners. This shelf causes the coolant to flow faster for better cooling of the cylinder liner. The coolant is pumped up through water directors into the cylinder heads. The coolant flows through passages around these items in the cylinder head: valves, valve seat inserts, spark plug adapter and exhaust outlets.The coolant exits the cylinder heads through tubes and the coolant flows into the water manifold.Coolant flows through the water manifold into lines for the turbocharger turbine housing and for the exhaust bypass valve. The coolant returns to the water manifold.Air is vented from the high points of the cooling system. The vent line from the connection must be straight and the vent line must have a slight upward slope. The vent must not be obstructed. The water manifold directs the coolant to the water temperature regulator housing. The engine has eight water temperature regulators. The water temperature regulators control the direction of the coolant flow according to the coolant temperature.When the coolant achieves normal operating temperature, the water temperature regulators open and coolant flow is divided. Most of the coolant goes through the radiator or through the heat exchanger. This coolant circulates back to the jacket water pump. The remainder of the coolant goes through a bypass tube to the jacket water pump.Note: The water temperature regulators are necessary to maintain the correct engine temperature. If the water temperature regulators are not installed in the system, there is
