Cooling System Description

The cooling system maintains engine temperature at an efficient level during all engine operating conditions.
A thermostat controls coolant circulation. The thermostat remains closed until the engine reaches normal operating temperature. When the engine is cold, coolant does not circulate through the radiator. This allows for faster engine warm-up. When the engine reaches normal operating temperature, the thermostat opens, and the coolant circulates through the radiator in order to keep the engine from overheating.
Remove the surge tank pressure cap in order to add coolant.
