GENERAL DESCRIPTION
The cooling system consists of the radiator cap,
radiator, water reservoir tank, hoses, water
pump, cooling fan
&
clutch, thermostat. The
radiator is of tube-and-fin type.
Cooling System Circulation
During engine warm-up (thermostat closed),
the water pump discharges coolant into the
water jacket chamber adjacent to No. 1 cylinder.
Coolant then flows through the cylinder block
and the cylinder head. Coolant then returns to
the water pump through intake manifold, heater
inlet hose, heater unit, heater outlet hose, and
water intake pipe.
During normal temperatures (thermostat open),
coolant takes the same basic route but is now
allowed to flow past the thermostat, the inlet
hose and the radiator, and then back to the
water pump through the outlet hose and the
water intake pipe.
