Why does the radiator leak when the bearing goes out?
It starts leaking when the bearing is going out so that it will be replaced prior to a complete failure. As for the vehicle still overheating, if all of the parts you have replaced are working fine, then you may have an air flow issue through the radiator. If this was the case, the vehicle would still cool at higher speeds and just not around town.

What should I do if my car is overheating all the time?
If it gets hot at all times, then it may have a clogged radiator, or more commonly a leaking head gasket. I would perform a block test prior to changing anything else. If that fails the test, then the engine will need to be disassembled and repaired. If it passes, then it may need a radiator.
What causes a radiator to overheat and leak coolant?
The typical aluminum head swells most in the middle, which can crush the head gasket. This will cause a loss of torque in the gasket, allowing coolant and combustion leaks to occur. If the coolant gets hot enough to boil, it may cause old hoses or an age-weakened radiator to burst.

What happens when the thermostat on a car fails to open?
Finally, the thermostat must be doing its job to keep the engine’s average temperature within the normal range. If the thermostat fails to open; it will effectively block the flow of coolant and the engine will overheat. Severe overheating can often damage a good thermostat. If the engine has overheated replace the thermostat.
