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…

A pressure-vent cap is used on the cross-flow radiator to allow a buildup of 103 kPa (15 psi) in the cooling system. This pressure raises…

See Figure 2-51. The radiator holds a large volume of coolant in close contact with flowing air. This allows the radiator to transfer heat from…

1. NOISE Fan noise is sometimes evident under the following normal conditions: a. When clutch is engaged for maximum cooling. b. During first few minutes…

There are two viscous clutch members (Figure 246). The clutch plate is splined to the pulley shaft and becomes the driving member. The driven member…

The 6.2L Coolant Fan is not directly driven. The engine fan is mounted on the water pump shaft and is driven by the same belt…
