2002 Dodge Dakota overheats temp gauge at normal level

When driving my 4.7L Dakota my temp gauge is in normal range, but after parking it my cooling system is bubbling and after checking my level I am low on antifreeze. It was occasional after I replaced my upper hose with radiator cap being part of my hose, now I cannot go to work and back. I have had my radiator flushed not to long ago. Any suggestions and help would be appreciated.

    seems likely that the cause is air bubbles in the cooling system - this could result after radiator flush. re-flush/re-bleed cooling system so there is for-sure no air in there. if that doesn't help, the next things to consider are: thermostat (test it by running the heat in the cabin as engine heats up), water-pump (look for drips), engine gaskets (look for evidence of foamy or milk-chocolate-looking oil on dipstick or crankcase.)

    Thx for your response. After reading other comments here from previous problems I ran truck with radiator cap off and then with heater on, didn't really see bubbles but some water flowed out from cap. Did a test drive, all seems to be OK (haven't drove long distance yet). Will do that today.
