Some leaks won't reveal themselves until they are under sufficient pressure. With the system pressurized you'll be able to either see or hear the leak(s) and have the engine off. And you can verify the pressure holds steady and no additional leaks are present elsewhere afterwards. I have found waterpumps that will only leak when you wobble the pulley by hand with the belt off. When using a pressure tester don't exceed the radiator cap's psi rating to be safe. In this case that's about 16 psi. If you don't own one places like Advanced Auto, Oreilly, and Autozone rent them with refundable deposits which makes it ideal for seldom use. You can also buy the tools outright. The Autozone unit comes with an adapter to also pressure test the radiator cap itself. I bought my own pressure tester since I find myself using it rather often. Great tool for finding coolant leaks.  |
