Information:
A pressure type cooling system offers two advantages:
The cooling system can operate safely at a temperature that is higher than the normal boiling point of water.
The cooling system prevents cavitation in the water pump.Cavitation is the sudden formation of low pressure bubbles by mechanical forces in liquids. The formation of air or steam pockets is more difficult within a pressure type cooling system.Raw Water Circuit
The auxiliary water pump that is used for the raw water circuit is located on the left hand side of the cylinder block. The water pump is driven by the front gear train.In many instances, a separate cooling source is used to supply coolant to the aftercooler. The coolant supply for this raw water circuit is sea water. A special pump is needed to move the coolant through the system. A bronze pump is used for a sea water cooling system. This type of pump will resist the corrosive action of the coolant that passes through the pump.Raw water is drawn in through the inlet of the auxiliary water pump. The raw water will flow through the fuel cooler before the auxiliary water pump inlet if the engine is equipped with the optional fuel cooler. The raw water is forced out of the pump and into the aftercooler. The raw water flows through the aftercooler and exits at the end of the aftercooler. The raw water then travels through the heat exchanger, and the water cooled exhaust elbow. The raw water is then discharged.Engine Coolant Flow Circuit
The water pump that is used for engine coolant is located on the right hand side of the cylinder block. The water pump is driven by the front gear train.Coolant from the heat exchanger is pulled into the inlet of the water pump by impeller rotation. The coolant exits the water pump and flows directly into the engine oil cooler.After the water exits the oil cooler, the water is dispersed to three main components: cylinder block and head, turbocharger and exhaust manifold.The coolant that was directed to the cylinder block next flows into the cylinder head.The coolant exits the cylinder head and combines with the flow of coolant from the exhaust manifold and the turbocharger. This combined coolant flows to the
