4) Water Pump
The belt-driven centrifugal water pump consists of an impeller, a drive shaft, and a belt pulley.
The impeller is supported by a completely sealed bearing.
The water pump is serviced as an assembly and, therefore, cannot be disassembled.
5) Thermostat
A wax pellet-type thermostat controls the flow of the engine coolant through the engine cooling system.
The thermostat is mounted in the thermostat housing to the front of the cylinder head.
The thermostat stops the flow of the engine coolant from the engine to the radiator to provide faste
r
warm-up, and to regulate the coolant temperature. The thermostat remains closed while the engine
coolant is cold, preventing circulation of the engine coolant through the radiator. At this point, the engine
coolant is allowed to circulate only throughout the heater core to warm it quickly and evenly.
As the engine warms, the thermostat opens. This allows the engine coolant to flow through the radiato
r
wherethe heat is dissipated. This opening and closing of the thermostat permits enough engine coolant
to enter the radiator to keep the engine within proper engine temperature operating limits.
The wax pellet in the thermostat is hermetically sealed in a metal case. The wax element of the
thermostat expands when it is heated and contracts when it is cooled.
As the vehicle is driven and the engine warms, the engine coolant temperature increases. When the
engine coolant reaches a specified temperature, the wax pellet element in the thermostat expands and
exerts pressure against the metal case, forcing the valve open. This allows the engine coolant to flow
through the engine cooling system and cool the engine.
As the wax pellet cools, the contraction allows a spring to close the valve.
The thermostat begins to open at 87°C(188.6 °F) and is fully open at 102°C(215.6°F). The
thermostat closes at 85°C (187°F).
6) Electric Cooling Fan
Keep hands, tools, and clothing away from the engine cooling fans to help prevent personal injury.
This fan is electric and can turn on even when the engine is not running. -
If a fan blade is bent or damaged in any way, no attempt should be made to repair or reuse the
damaged part. A bent or damaged fan assembly should always be replaced with a new one to
prevent possible injury. -
