What the Libra zodiac sign is all about: Libra is the seventh of the 12 zodiac signs, which begins its cycle in early fall every year during Libra seasonâwhich falls around September 23-October 22.
How it works. This schematic shows the component parts of a typical leak-down tester. The gauge on the right is held at a standard pressure by adjusting the pressure regulator while the gauge on the left shows an example reading of 85-or 15% leakage.
If the cooling system has been acting up, and you canât seem to find the cause of the problem, one thing that you can do is to pressure test the systemâthere could be a leak somewhere. All you need for this test is a cooling system pressure tester and a little amount of time to allot for the job. The tester comes with a gauge to indicate pressure and a pumping mechanism for building up the pressure in the system. You need to build the pressure to make finding leaks easy.
