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.
