The cooling system consists of the following major components:

The cooling system functions to maintain an efficient engine temperature during all engine operating conditions. The thermostat remains closed until the engine reaches the proper operating temperatures. When the engine is cold, the coolant does not circulate through the radiator, allowing the engine to warm up faster. When the engine reaches the normal operating temperatures, the thermostat opens and the coolant begins to circulate through the radiator in order to keep the engine from overheating.

The water pump draws the coolant from the radiator. The coolant is then circulated through the cooling jackets in the following components, then back to the radiator to be cooled:

The engine coolant is drawn from the water pump and circulated through internal passages in the cylinder heads and engine block. Vapor is vented off through the vapor vent pipes. The heated coolant is then directed back to the radiator. A separate coolant flow loop is available from the coolant pump to the heater core and back to the coolant pump to provide passenger compartment heat and defrost.

The radiator surge tank provides a coolant fill point and a central cooling system air bleed location. The tank is translucent on the lower half for coolant level viewing.
