Cooling System Problems - Overheating

I have a 95 Cherokee Sport 4.0 . This is the first vehicle I've ever decided to work on. And am relatively new at it. I've only had the vehicle 4 months. Anyways, I'm really desperate right now. I had replaced the rad and water pump. Everything was fine. Now it overheats in five minutes. The vent doesn't blow hot air even when the engine's overheating and the upper rad hose is cold. I replaced the thermostat, but no change. There is plenty of coolant in the reservoir. Any advice / info would be GREATLY appreciated. Thanks.

Burp the system of air. ASAP before you drive it and overheat any more.

The thing is. I drove it about 5 times for a total of about 60 miles. Then on the 6th time about 15 minutes in it suddenly started blowing cold air and overheated. Could air be in the system that long then suddenly effect it?

I just did my thermostat over the weekend, having done thermostats on hundreds if not a thousand cars, I find that jeeps more then any other vehical have more trouble getting that last gasp of air out.
What I do to be sure air is out leave rad cap loose one click and start jeep, stay on passenger side with antifreeze at the ready grab the upper hoseand wait for it to get warm then remove cap and add.
2 CAUTIONS TO BE CAREFUL OF ANTIFREEZE IS OIL AND DOES BURN BADLY SO BE CAREFUL 1- if upper hose has preasure (test by squeezing) antifreeze will boil over radiator when removing cap. 2- I said stand on passenger side not to check hose but incase the radiator cap is not on tight enough (1st lock) it could blow off.
If at any time you feel the motors to hot to remove cap shut off and let stand to cool before trying again.

i converted to a open cooling system not too long ago.. had a overheating problem like explained

turns out that the coolant bootle on the closed sytle cooling system was like a big air bubble and not letting the coolant flow correctly

i fixed the problem by buying a newer heater control valve

since then i dont even think ive gone past 205*F

if burping the system doesnt work, might wanna try the heater control valve
