What does the thermostat on a Jeep Cherokee do?
Never touch the radiator cap unless the vehicle is ICE COLD. The job of your Cherokee’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.
Why is my Jeep Cherokee overheating so much?
If your radiator overflow is full (and you radiator fan is kicking on), it is very likely that a bad thermostat or bad water pump are causing your Cherokee to overheat. Of these two, the thermostat fails more often than the water pump. It’s also much more affordable and easier to get to.
How does the cooling system on a Jeep Cherokee work?
Your Cherokee’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. If any part of this system fails, your Cherokee will eventually overheat.

They both should feel warm or hot to the touch with the engine on. If one of the hoses is hot, and the other one is cold, that is a pretty good indication that the heater core is clogged. If the neither hose has any heat, you may have air in the cooling system, low fluid, or low pressure.
