You don't have to pressurize the system. You can just look for dried coolant, because it's not invisible.

You can always go play tea with your dollies while it's cooling off.

No, but maybe you should. I would just do what I've done for the past 30 years, which is look for traces of the leak with the motor off. Because it's not invisible. And this is not nearly as complicated as you're trying to make it.

If there is coolant leaking from the weep hole, the water pump needs to be replaced. Period. Unless you're suggesting that he should ignore a leaking water pump, which would be unbelievably stupid. You're not suggesting something so unbelievably stupid are you?

Well, he
has diagnosed that he has a leak, unless the coolant just magically appeared from a land where unicorns piss coolant into our dimension.

Is that obvious? How do you know? He doesn't know, because he hasn't looked.
Maybe I'm old school, but in 30 years I've never had to apply pressure to a cooling system to find a leak when I could see the coolant with my own eyes after just running the motor. Traces of the coolant are usually visible, and the expense and extra trouble of a pressure tester doesn't actually prevent you from having to poke your noggin in there and look for yourself. Diagnosing this is something he could go out and do
right now if he wanted without having to do any extra research or buy any extra equipment.
It just really isn't that complicated.
