AutoZone has a cooling system pressure tester on loaner program that should make diagnosis a snap. It clips in place of your rad cap, you pump it up like a bike tire pump until the gauge reads whatever your cap is rated at (usually ~16psig) and it should hold that nearly indefinitely. If the gauge drops, you have a leak.
Keep re-pressurizing it enough and you might eventually force a bubble into your PS reservoir, but I'm speculating on that.
