Cooling System Description

The cooling system maintains engine temperature at an efficient level during all engine operating conditions. The cooling system consists of the following components:
^ A radiator
^ A radiator pressure cap
^ A coolant recovery reservoir
^ A water pump
^ A thermostat
^ Two electric engine cooling fans
^ A drive belt
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.
These engines have a closed cooling system. This means you can add coolant to the coolant recovery reservoir without removing the pressure cap from the radiator.
