Makes perfect sense to me: pressure test it. If you don't have one, you should be able to borrow a cooling system pressure tester from AutoZone, etc. Typically, they charge you for the tool and then refund your money when you return it. I found this particular tool so useful I kept it, but then I had three 20+ year old cars at the time.
