Default overheating with new oem thermostat!!!

Previous owner have removed the thermostat on my 07 sti. Its been this way since I got my car last year. Anyway had zero problem with it but since winter is coming I decided to put new oem thermostat.

I just installed it today. Started the car, let it warm up, all good. Drove for 10 min and then my gauge went up to 226 F. I just hold it there till I got a safe spot to park.

what could be wrong with new oem thermostat and new coolant??? I put my ac to hot and it was blowing really hot hot air so this mean hot fuilds is passing thru and no air lock or whatever???

You probably didn't get every air bubble out. Reburb the system.

Pro tip when burping system: jack front of car up as high as possible. You did put the thermo in the correct way as well? The little air release valve needs to be at the top of housing.
