Sometimes I have to refill my radiator with liquid, I got my radiator tested at the shop there is nothing wrong with it... That's why I ask this question.
Thanks

Assuming you have a correct full functioning pressure cap on your system and a coolant recovery tank all street systems get hotter when the engine works harder. Also we must assume your cooling system has no pressure leaks.
Weather you're pulling a load or driving fast it all boils down to this. Today's radiators are usually one row thick of cooling tubes and covered in the front by the AC. condenser which robs it of cool air. The pressure cap on the radiator raises the boiling point of the coolant. The higher the pressure stamped on the cap the higher the boiling point of the coolant. It's never a good idea to arbitrarily stick on a 22 - 32 lb. radiator cap just to raise the boiling point of the stuff inside the radiator. You'll split it in half. Antifreeze does not have a thing to do with cooling efficiency.
What does help is an over sized fan / electric fan / pusher electric fan and or an oversized radiator. It can be wider thicker or taller. As coolant gets hotter it expands therefore the radiator cap realeses the coolant depending upon the pressure rating into the coolant recovery tank. As the coolant cools inside the block, heads and radiator a second relief valve inside the pressure cap allows coolant to return to the cooling system because of the vacuum created by the coolant inside the radiator and engine.

Some radiators have overflow valves so boiling fluid is vented so the radiator or hose doesn't blow. So if the radiator overheats you will lose fluid. The radiator may be OK but have the shop check the thermostat.

You get overheating mainly by running the engine and not going anywhere like running it in a traffic jam. If you are travelling then the moving air cools it down. Radiators do lose a little bit all the time.

No, you have a slow coolant leak that burns up into steam before you see it. However, have your engine checked for a leaking head gasket as another possibility. Make sure to keep the radiator topped off with coolant when it's cold.

i think u might have a leak u need to take it back to the mechanic u probably need a new radiator take it to a different mechanic it can also be ur fans not turning and its causing it to overheat, u might want to flush ur radiator it might be claught up too.

should be going into the overflow not out completly
It is possible to heat the engine and use some coolant.

Maybe the cover isn't screwed on right
