The water pumps on every car that I ever owned (including my W124, which lost the water pump several years ago), begin to leak. Most water pumps have "weep holes" that start to leak when the seals go bad.
On the W124, the failure was dramatic...fine one day, coolant all over the garage floor the next.
Cooling system issues began to bring themselves to attention around 100K...water pump, radiator neck, expansion tank, cap, thermostat, etc.
Now that you are getting your new gasket, keep an eye out for the rest of the components...the overheating may just have been enough stress to cause other cooling components to compromise themselves...
