I did mention I remove radiator cap and warmed engine. (I will also note my driveway is on a incline so the radiator cap is at a higher level than the thermosat) when the thermosat opened and the coolant level dropped I refilled radiator to proper level. This is also an alternative way to purge air from system if you rather not mess with the bolt on top of the thermosat housing. It still overheat and lost heat this morning? I also check the fluid levels a few hours later and they were fine. At this point I did remove the bolt in the thermosat housingand poured antifreeze directly into it until it flowed out of the top of the radiator (cap removed). this did not fix the problem still overheated and lost heat on ride home from work.
