Sometimes a vacuume leak can cause overheating problems too.
SOURCE: 97 Monte carlo is overheating.
If the thermostat is sticking closed you can maybe tap the housing with a hammer or other tool while it is running, it may cause it to open up and you will see the temp going down on the gauge. As I recall the thermostat is at the front, within easy reach, so you could go ahead and take the thermostat out, reassemble and see if you still have a problem. For testing it won't hurt anything to run without it, just make sure to replace it with a new one if it's bad. There's also your waterpump and possibly a fan clutch. If it has electric fan make sure they are coming on, if not maybe the fan itself or possibly relays can be bad. Please rate this. Thanks and good luck.

Have you unhooked the battery since you put the freon in? If not, do it.
SOURCE: at idle car runs hot, but when driving it cools down.
Is the heater working ok if not it may be airlocked need's bled. WHen it heat's up so quickly then the only other thing is a faulty thermostat stuck closed. It may also be the radiator but unlikely because It should take longer than 5 minutes for it to overheat.
SOURCE: 92 honda accord is running hot but radiator fan is not turning
Connect the fan directly to the battery to test
Sounds like the front of the radiator or A/C condenser is clogged up...take a water hose and try to clean any debre from the front, so air can pass freely...
