I assume you are talking about removing trapped air from the cooling system. Park uphill or jack up the front of the vehicle. Remove the radiator cap, turn heater control to hot, and start the engine. Keep the coolant level full, while the engine runs. Watch for air bubbles escaping from the radiator. When you see none, all the air is purged. It may also have a Schroeder valve somewhere on the cooling system at the highest point that can be used to purge air.
Simple, to remove the air so the gas will reach the appliance
pipe rolling pipe rolling In some systems used in hazardous environments, like computers on oil and gas rigs where explosive fumes are present, a purge air system is used to flush the equipment with clean air before it is turned on, so the air inside the equipment won't ignite from a switch making contact or an electrical problem.

Purge slowly into a pail or bucket in the telemotor hydraulic system purging valve until such a time pure hydraulic oil are coming out from the purging valve.
Open a vent valve to purge the air and open the supply valve to let in water. Every hydronic (forced hot water) system has a system fill or supply valve, often connected to domestic cold water through a flow-check valve and a pressure-reducing valve. However, simply opening this valve with the rest of the system closed will merely pressurize the system with air. The system should also have one or more automatic air vents, plus a purging valve or two. By allowing air to vent (often out the top) and air bubbles to pour out through the purge valves, you can mostly fill the hydronic system with water. As the system is then heated, more air bubbles will form from dissolved air and be vented by the automatic vents. If it is not automatically vented, the top-most loop of the system may accumulate air and stop working until it is purged by opening a vent until water comes out.

have it checked by dealer something is amiss
No. A 2001 Jeep does not have a cabin filter.
One of the reasons a 2000 Jeep Cherokee heater would randomly blow cold air and then hot air and then cold might be that there is a problem with the hot/cold duct. The air or a vent might be inadvertently blowing periodically.

Looking for the radiator cooling fan air conditioning wiring diagrams for 2000 cherokee laredo
i got my 2000 jeep grand cherokee to go 110 ish but it has a spector cold air intake and a thurst muffler and oil change
I need a routing diagram for the serpentine belt on a 1998 Jeep Wranger, 4 cylinder, with air conditioning
quickly just take out bolts fast air gun easy
The Jeep Grand Cherokee air conditioning evaporator hose diagram can be obtained from most Jeep dealerships. The diagram can also be found at most auto-parts stores.
