Assuming the cooling system was bled correctly, have you tested if the fan clutch is working properly? Also, does it heat up at any driving speed? Hopefully not a blown headgasket .

Yes i let it iddle and after some minutes ot starts heating up yes the fan works and i dont think theres any head gasket broken.

Does it heat up at higher speeds like on the freeway? You can test the fan by trying to spin by hand while the engine is off. There should be some resistance when trying to spin it. If it's easy to spin then it might be failing.

No only when i exiting the highway thats when it starts heating up

Check oil if it is white then its a bad head gasket
