To keep the car engine from over heating
for towing and heavy-duty use.
Not all cars do (eg electric cars). However if the car is powered by a combustion engine then the engine produces heat and this heat must be dissipated or the engine will overheat and cease. This is why combustion engine powered vehicles need a cooling system/radiator.
you need to get the engine checked
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 :)
A radiator cools the water that flows around the engine.
It cools down the lubricant. and lubricates the engine piston to stop it from snapping.

The car engine radiator.
how can you tell if you need a radiator in a 99 cadillac northstar engine
Radiator stores engine coolant for circulation throughout the engine The radiator is placed at the front of the engine and exposed to the atmosphere to keep coolant cool to maintain proper engine temperature
The radiator cools the water which then goes to your engine to cool it off, as cool water enters your engine hot water from the engine enters your radiator
