Well, in my house it was the catalytic converter, but I'll tell you that I took the pipe out to rule it out faster

It would be important for you to remove the spark plugs to see what color they come out, that way we'll know if there's an excess of fuel in the mixture; if so, it could be the temperature sensor or the oxygen sensor.

Look, I just checked the oxygen sensors and they're really carbonized, but the computer isn't showing any error codes

Oh, by the way, what gauge are the spark plugs? And they don't look dirty. One of them has a little oil stain on the threads, but the electrode and everything else isn't stained. And since you seem to know about cars, could you tell me why there's so much pressure in the radiator even when the car is cold?

The problem with the temperature rising could be that the thermostat is stuck closed and not opening, or the radiator is clogged; check the condition of those components.
