Overheating

You can pressure test the radiator, and do a leak down test.
That's all I got.

WHAT! No civics in stock -

Without temp readings on the gauge, you don't know what temp your car was at. As others have mentioned, you need a scanner that can read engine coolant temps to be able to determine if you really have an issue.

That being said, with the turbo charger, you've added a heat source to your cooling (and oiling) system. If you did not make any changes to the heat transfer capacity of your cooling system you will run into overheating issues under certain circumstances.

With the A/C on, the air that passes over the condenser becomes warmer and then when it gets to the radiator has less capacity to transfer heat. So in the case of running with a turbo and a/c on you have more heat in your cooling system and less ability to transfer that heat out.

Assuming you have no leaks, swapping a radiator out for a direct replacement part is not going to help you. If you get a larger one, it will help by increasing heat transfer capability.

Changing your thermostat to a lower temperature will also not help you unless you want your car to run at a cooler temp all the time. If you generate more heat in your cooling system than the system can remove the lower temp thermostat is only going to delay your overheating issue.

All in all, I would do as others have said. Ensure everything is functioning as designed. If it is and you still have overheating issues I would start with a more robust radiator that can transfer more heat.

So far everything is running well. No visible leaks, fan turns on when ac is on. I just got a coolant flush so im assuming theres no air bubble (might try to bleed again). But thank you so much for this

And if you still have issues after making sure there's no air in the radiator, you can buy an air/oil cooler.

That stock gauge is so inaccurate.

That's how I read the thread title every time.

Is not - that's the way it's designed, so as not to alarm people who "can't handle the truth" -

So, back-in-the-day, did you do this to turn odometers back or did you hook the cable up to a drill and let it run backwards all night? - fess up now -

Piff that's the ghetto con mans way.
We had a guy in a salvage yard that would pull low mile wrecks's vins and gauge clusters. We just did the swap before logging it into the DMV database.
Drilling out the rivets is not as hard as it seems. Hard part was windshield removal

WOW! What a deal, considering that civic on your lot only has 1,235 actual miles on it -
