Question about Jeep Liberty
Doesn't sound good ,head gasket I think,Napa sells a combustion leak detector for about 40 bucks ,simple to use ,just some blue fluid that turns green if there is "exhaust" in the cooling system,might be cheaper than having some shop guess.

It appears we have an Air lock scenario and you will need to perform a system Bleed.
Park the vehicle on level ground, when cold remove coolant filler cap, start engine and leave to idle, turn heater on full and blower to max. When engine reaches operating temperature watch and listen near coolant filler, keep clear as gurgling and hopefully a boil over should occur. Top up with very warm coolant and wait as it may do it again.
Check for heat inside vehicle if warm replace coolant cap but keep an eye on temperature gauge as the ~Air lock may have moved on from heater matrix/core so proceedure needs to be carried out again from COLD.
If persistent boil ups/over attention must made in the cylinder head
or gasket area, or possibly water pump?

I had a 1998 Dodge Ram that Overheated alot. I changed the Radiators and Thermostats a couple of times. I finally pulled the water pump and found the impellers had been eaten away by electrolysis. I am not saying this is your problem but it is worth a shot. You can check for electrolysis with a voltmeter put one probe on the negative battery terminal and the other in the coolant. You want a reading of less than 0.2 volts.

It could be the thermostat, or the electric cooling fans are not coming on, if they are working, change the thermostat.
To find it------ follow the top radiator hose to the thermostat housing, the thermostat is in the housing.
