ENGINE COOLING SYSTEM
Under normal driving conditions, the
coolant temperature gauge should
read between 170°-195°F
(76°-90.6°C), and the temperature
should not exceed 205°F (96°C).
When the engine coolant
temperature reaches 212°F
(100°C), the alarm and indicator
lights are activated. If engine
coolant temperature continues
rising to 220°F (104.4°C), engine
shutdown occurs.
Engine cooling is accomplished
through the use of a belt-driven 3
speed electro-magnetic fan clutch.
The clutch engages after the engine
fan controller monitors both water
and oil temperatures. When both
electro-magnetic couplings are
de-energized, the fan operates at
between 200 to 300 rpm.
When coupling 1 engages, the fan
operates at 800 rpm. Coupling 2
operates at 2200 rpm.
The engine coolant tank is located
above the radiator compartment on
the roadside of the vehicle.
As an additional safety precaution,
two sight glass are installed on the
tank for convenience.
