How does the cooling system on a Jeep Liberty work?
Your Liberty’s cooling system works by cycling the engine coolant from the engine through the radiator. The water pump pushes the water through the entire system. The thermostat opens up once the engine reaches operating temperature and allows coolant in.

Why is the thermostat on my Jeep Liberty not working?
The job of your Liberty’s thermostat is to regulate the temperature of the engine. It does this by allowing water to enter the engine when it is getting hot, and by keeping coolant from entering while the vehicle warms up. Sometimes when a thermostat goes bad, it stays stuck open. This allows the coolant to continuously enter the engine.
How does the heater on a Jeep Liberty work?
At the simplest level possible, the heater works by passing hot coolant from the engine into a tiny radiator called the heater core. At this point, the blower motor blows air across the it and the newly heated air blows on to the driver and passengers. If the heater has stopped working in your Liberty, this process has failed in one way or another.
What kind of coolant does a Jeep Liberty use?
Water pump: Pumps coolant through the cooling system (when the thermostat opens) creates flow and is always pumping or cycling coolant. Heat exchangers or more commonly radiator or heater core: These give off heat to the air that goes through the radiator or heater core. Coolant: a 50/50 mix of coolant and water is required.
