COOLING SYSTEM
GENERAL DESCRIPTION
COOLANT FLOW
The engine cooling system consists of the radiator, the water pump, the cooling fan, and the thermostat.
To quickly increase cold engine coolant temperature for smooth engine operation, the coolant is circulated
by the water pump and thermostat through the by-pass hose and back to the cylinder body. The coolant
does not circulate through the radiator.
When the coolant temperature reaches 82°C (180°F), the thermostat will begin to open and a gradually
increasing amount of coolant will circulate through the radiator.
The thermostat will be fully open when the coolant temperature reaches 95°C (203°F). All of the coolant is
now circulating through the radiator for effective engine coolant.
