The most common reason for overheating of a car radiator is that there is not enough water in the radiator. Radiators can lose water in a variety of ways, and often need to be refilled. The other possibility is that the water is not being circulated properly. I should add that cars do heat up quite a bit in the sunlight on a hot day, which adds significantly to the chances of overheating the radiator.

Why does a car radiator produce steam when broken down in the summer?
There are plenty of ways a car can break down without the radiator being a part of the cause. As for the reason you'd see steam from a radiator, it would escape if there was a leak in the radiator or the hoses, or if the cap was opened. The contents in a radiator are very hot - hot enough to produce steam.
What causes car to stall when it gets hot?
A car engine is made with many moving parts that fit together very precisely. When these parts get hot, they expand, but they do not all expand to exactly the same degree. So parts which fit in a certain temperature range, will cease to fit in a higher temperature range. That is why the car will stall if it gets too hot. If the radiator is working correctly, the engine will never get too hot.
When do you know you need a new radiator?
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.
