6B-2 ENGINE COOLING
GENERAL DESCRIPTION
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 heat. 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.
