How to bleed air out of the Jeep Wrangler?
Park with the nose at a incline and the Radiator cap off. Start it up and wait to get to operating temp. Then squeeze the upper hose to work any of the bubbles out. You should see the level of antifreeze drop in the radiator, fill it back to full as the level drops.
Where is the cooling system on a Jeep Cherokee?
Park the nose of your rig downhill so that the engine is visibly tilted nose down so any air pockets will flow to the back of the head where the computer’s temp sensor is. (This is NOT the sender for the electric fan. On factory closed cooling systems, that is in the radiator tank on the driver side below/beside air box.)
Why does my Jeep Cherokee have a burp air system?
Burping air from a closed cooling system. THE HARD WAY: Let’s face it, burping trapped air from the head of a 4.0L in-line six cylinder is an easy way to burn your hands or get scalded when ya remove the temperature gauge sender on the head of a hot engine.
How can I clear air from my radiator?
Let me know if that link doesn’t work. Anytime you change the radiator, change the thermostat, drain your coolant, change water pump, or do an engine swap, you need to clear the radiator of air bubbles. This technique is called burping the radiator. This will also fix your heater.

What causes a jeep radiator to overheat?
As the engine heats up, the thermostat opens and allows coolant to circulate through out the entire coolant system. The thermostat can fail by either sticking open, sticking closed, or completely breaking and cause an internal blockage. All these scenarios can cause overheating, no hot air output, or low running temps.
