LOCATIONS AND DESCRIPTIONS OF MAJOR COMPONENTS Water Pump The water pump (Figure 1, Item 7) is mounted on the top of the oil cooler and driven by belts from the camshaft front pulley. It circulates coolant through the cylinder block, cylinder heads, and oil cooler. Valve Rocker Covers The valve rocker covers (Figure 1, Item 2) enclose the valve and injector rocker arm mechanisms located on top of cylinder heads. Engine Oil Cooler The engine oil cooler (Figure 1, Item 6) is mounted on lower left side of engine block. It uses engine coolant to cool engine oil. Models 5063-5299 and 5063-5392 have the transmission coolers in the same housing. Transmission Oil Cooler The transmission oil cooler (Figure 1, Item 4) is included with the engine for models 5063-5393 and 5063-539L. It is mounted on left side of the engine block. It uses engine coolant to cool transmission oil. Exhaust Manifolds The exhaust manifolds (Figure 1, Item 5) are attached directly to cylinder heads. For all, except model 5063-5299, they route exhaust gases through attached exhaust piping to the turbocharger. Oil Level Gauge Rod The oil level gauge rod rod (Figure 1, Item 3) is mounted differently on each model engine. On model 5063-5299, it is mounted on the left rear of the cylinder head. On model 5063-5392, it is mounted on the right rear of the cylinder head. On models 5063-5393 and 5063-539L, it is mounted on the right front of the cylinder head. Thermostat and Housing Assembly The thermostat and housing assembly (Figure 1, Item 1) is mounted on the front of the left cylinder head and connected to the right cylinder head with crossover tube. It controls coolant temperature by restricting coolant flow to the radiator. TM 9-2815-205-24 0002 0002-2
