Not enough info. Why did you change the thermostat?

A blown headgasket is one possibility too.

i change the radiator to a Mishimoto and when I changed it it started overheating I burped the car with distilled water no more burps and it’s still over heated changed the thermostat to see if it would help and welp it didn’t

when you crank the heater, is the air hot? If it's not, you still have air in the system.

Z's are difficult to bleed, just takes time.

here's a funnel you might try also maybe check your water pump it's internal located in the engine I had to have mine changed out I went through the same exact situation,went ahead and replaced my radiator with the Mishimoto and changed out all my hoses and up graded them and even replace the thermostat as well hope this might help!

Hey, people with bad grammar need love too :icon39:

When you bleed your system , make sure to hit the upper bleed point. See the manual at the beginning of this vid.
Another thing you could do, (But just do it the right way) is jack the front end way up and keep bleeding the radiator. That worked for me.

Change back to oem radiator. IDK why people swap and think it's so much better. There's def air in the system

+1. You wan to jack that front end up, crank the heat in the car, and burp the system. Burping this system is notoriously time consuming, and this method seems to work best.

Just because you replaced the thermostat doesn't mean the new one is any good. Try taking out the thermostat. Are you sure the car is overheating, rather than the temp gauge malfunctioning? If the water pump has failed, this could be the problem.
