Cooling System: Description and Operation

SYSTEM OPERATION
The cooling system, which consists of a radiator, surge tank, electric cooling fans, thermostat/housing and water pump, works to maintain engine temperature at an efficient level during all engine operating conditions. Coolant is drawn from the radiator by the water pump and circulated through coolant jackets in the engine cylinder block and cylinder heads. It is then directed back to the radiator. The system directs some coolant through hoses to the heater core to provide defrost and passenger compartment heat. A surge tank is connected to the cooling system. Pressurized coolant will continually flow through the surge tank.
