Yes, a car needs a radiator to run because it stores the coolant for the engine and dispenses it when needed. So, if it didn't have one the car would overheat and not be able to move :)
If your radiator is leaking then you will need to replace it. Additionally, if you find that your car is constantly running hot you will need a new radiator.

A car can overheat for several reasons. You may need to replace your water pump. You may have a leak in the radiator itself. You may need to add more 50/50 mix of radiator fluid and water to your car. You could also have leaks or holes in the radiator hoses. You may also need a new cooling fan for the radiator.
for towing and heavy-duty use.
question- what was the car without a radiator? well it's probly a car without a stinking radiator,,,
The radiator will need to be replaced. Sometimes, it may seem that the radiator itself is leaking but it could be the radiator "hose" that is leaking. In this case, the radiator hose needs to be replaced and clamped tightly.
You need to go get your car looked at by an auto repairman if you have a crack in your auto radiator. They can tell you if it needs replaced or just fixed.
you need to get the engine checked
