You attach a pressure test kit to where the radiator cap goes, and pressurize the system. If it holds pressure, it's good.
First, remove the radiator cap. If car is still warm, turn radiator cap about 1/4 turn to relieve the pressure. Then, I find it much easier to remove the lower radiator hose from the radiator. It's much quicker than draining it from the petcock.

Actually if car is not running hot and temp gauge is staying within range then car is probably fine. I've seen a few that didn't have a lot of pressure on hoses because the flow of coolant was just that good. If you have too much pressure on a hose then you may need to worry.

The purpose of the overflow tube in a car's radiator system is to allow excess coolant to flow out of the radiator when the engine is hot and the coolant expands, preventing pressure buildup and potential damage to the radiator or engine.
