What happens when a radiator in a car overheats?

What should the temperature of a car radiator be?
Your car radiator allows your engine to operate within a “normal” temperature range; of about 195 to 220 degrees F. But, as efficient as today’s engines are; they still waste a lot of the heat energy they produce. Above all, the most common problem a car radiator falls prey to; is clogging (both internal and external) as well as leaks.
What causes a radiator to stop dissipating heat?
This can happen if the reinforcing spring inside the hose is missing or damaged. The most common problems radiators fall prey to are clogging (both internal and external) and leaks. Dirt, bugs and debris can block air flow through the core; and reduce the radiator’s ability to dissipate heat.
What causes a radiator to become clogged with coolant?

If the fan isn’t kicking in, then there a few things that could cause that. One of the reasons could be a faulty thermostat, as the thermostat tells the fan when to turn on and off. Another reason could be that the fan’s wiring harness is not getting power to actually turn the fan on.
Why does the coolant leak out of the radiator?
A coolant leak. While driving, the incoming air flow allows the radiator to keep the coolant temperature down. But when the car is driving at low speeds or at a standstill, it’s up to the fan to do that job. If the fan isn’t kicking in, then there a few things that could cause that.
