Cooling system
Why were you burping in the first place?
Did you recently replace any cooling system components?
What's the history (service life) of radiator, thermostat, water pump, etc...?
Try this if you want, on the pic with the red arrow there is a gear clamp with an 8mm head or you can use a flat screwdriver to loosen it.
Do this when the engine is fairly cool, grab the hose with the clamp loose and twist it so it turns freely then pull it partially off to see if there is any fluid coming from the hose.
If no or little fluid comes out remove the hose from the valve and put it somewhere that is a little higher than the heater control and put antifreeze in the rad until it comes out the hose...it will come out from the hose you removed first not the heater valve. That should get you heat fairly quickly after you relace the hose and tighten it.
That stop leak usually doesn't work anyway unless you pit in a quart or so.

Your water pump is in good condition?
If your thermostat is original, replace it.
Your radiator may be gummed up with head gasket sealer.
Check your ECT sensor probe for goop...if original, then replace it anyway.
Your heater core may be gummed up with head gasket sealer.......however, that is a more invasive project.
Start by swapping out your original radiator, thermostat and ECT sensor ..

i've said this many times before, i've never seen a head gasket failure on these engines! there was one that was close but it was not confirmed. i'm sure it's possible if intentionally done of course.
