The engine works hard and produces a lot more heat than when the car is driven on a leveled road. The car is usually driven slower on the uphill and there isn't as much air cooling the radiator. But the main reason it overheats is that the cooling system is malfunctioning.
Your car is starting to overheat or your thermostat is going out. Get it checked.
Generally, if your car overheats with the proper level of antifreeze, either your water pump has gone bad (not circulating fluid), the thermostat is stuck, or your radiator is clogged up inside. -NAPAman
Each car overheats at a different temperature you need to look up and find out on the internet
