Give a pressure of about 120 kPa (1.2 kgf/cm², 17.0 psi) and see if the system holds this pressure for 10 seconds.
If the pressure should fall during this 10-second interval, it means that there is a leaking point in the system. In such a case, inspect the entire system and replace the leaking component or part.
Warning! When removing the radiator cap tester, put a rag on the filler to prevent spouting of engine coolant.
Caution! Do not allow the pressure to exceed specified pressure, or the radiator can be damaged.
