The system has a vent line that runs under the car, when the system pressure exceeds the cap pressure rating (which drops from its original 18.2 PSIG over time and with use), coolant goes out the vent and onto the ground. Now that there is air space in the surge tank, air starts circulating in the system, and you get air pockets; and the car starts to overheat. All over a part that cost about $20 and should be tested and/or replaced regularly..............
