WARNING: This page is about a different car, the 2016 Dodge Charger and 2015 Dodge Charger. However, it is still accessible from the selected car via links, so may be relevant.

The cooling system regulates engine operating temperature. It allows the engine to reach normal operating temperature as quickly as possible. It also maintains normal operating temperature and prevents overheating.

The cooling system also provides a source of hot coolant for heating the passenger compartment and cooling the automatic transmission fluid (if equipped). The cooling system is pressurized and uses a centrifugal water pump to circulate coolant throughout the system.

When engine is cold and the thermostat is closed, the cooling system has no flow through the radiator. The coolant flows through the engine, water pump, and heater.
When engine is warm and the thermostat is open, coolant flows through the engine, radiator, heater, and water pump.
