See Figure 3-5. A combination intake manifold and cross over is used. It is a splider air plenum type which allows it to be completely…

Air moves without restriction through the air cleaner and intake manifold (Figure 3-1 and 3-2) to the combustion chamber. The chamber is filled with air,…

If you encounter a diesel engine that exhibits excessive oil consumption, low compression or excessive blowby and you suspect stuck piston rings as the cause,…

To determine if the valves or rings are the cause of low compression, a test should be made to determine the cylinder compression pressure. When…

A low coolant indicator system is used in 6.2L applications. See Figure 2-60. This system consists of a: • Module • Probe • Low coolant…

The 1985 6.2L cooling system has a pressurized coolant recovery tank.

• COOLANT FLOW A. Coolant is drawn from the radiator by the water pump. B. The pump pushes the coolant into both sides of the…

A pellet-type thermostat (Figure 2-56) is used in the coolant outlet passage to control the flow of engine coolant, to provide fast engine warm-up and…

The thermostat Figure 2-55 is placed in the coolant passage between the cylinder head and the top of the radiator. Its purpose is to close…

A temperature switch (Figure 2-54) activates a warning lamp in the instrument cluster should excessive coolant temperatures prevail in the engine. With optional instrumentation, a…
