GENERAL DESCRIPTION
The cooling system consists of the radiator cap, radiator, coolant reservoir, hoses, water pump, cooling fan, and
thermostat. The radiator is of tube-and-fin type.
WARNING:
Do not remove radiator cap to check engine coolant level; check coolant visually at the see-through
coolant reservoir.
Coolant should be added only to reservoir as necessary.
As long as there is pressure in the cooling system, the temperature can be considerably higher than
the boiling temperature of the solution in the radiator without causing the solution to boil. Removal
of the radiator cap while engine is hot and pressure is high will cause the solution to boil instanta-
neously and possibly with explosive force, spewing the solution over engine, fenders and person re-
moving cap. If the solution contains flammable anti-freeze such as alcohol (not recommended for use
at any time), there is also the possibility of causing a serious fire.
COOLING SYSTEM CIRCULATION
1) While the engine is warmed up (thermostat closed), coolant circulates as follows.
2) When coolant is warmed up to normal temperature and the thermostat opens, coolant passes through the radia-
tor core to be cooled as well as the above flow circuit.
