Cooling System Cooling Circuit
Fig.3-1
When the engine gets warm, the coolant flows to the water pump from the outlet in the lower left side of the radiator. After passing through the pump, the coolant is forced to the cylinder block. After cooling off the cylinder block, the coolant circulates in the cylinder head. Then the coolant flows through the thermostat and back into the radiator.
Antifreeze Solution To prevent freezing, add anti-freeze solution to the water which lowers the freezing point of the coolant. Before adding anti-freeze, inspect the cooling system to be sure it is clean and leaktight.
