I should be ready to test everything with all adapters. At least on the first machine everything went very well. Ha! Partially satisfied as I didn't have a bad radiator, just a clamp hanging out.
Pros
MANUAL PUMP LEAK: The radiator pressure tester uses aluminum pump cylinder, no plastic, 21-inch rubber and nylon resin hoses, brass fittings, strong and durable. 3 inch dial with index range from 0 to 35 psi (0 to 2.5 bar), easy to observe. Chrome plated brass quick coupling with safety valve connects to radiator adapters quickly and easily. The flat design of the control button is more convenient to press with the palm of your hand.
