When I drive over 100kp during the day, it overheats but same speed at night it doesn't, some time ago I took it for combustion test and I was told my car is fine there are no leaks.

Hello,

First thing you should check is the the radiator cooling fans. If the fans not operating properly the engine can overheat. As you said it does not overheat during the night time, as the outside temperature is lower than the day time. Which leads me to think might have one of the fan working or may not be working at full capacity.

Here are some helpful articles:

Please let me know if you have any questions.

Thank you.
