Checking For Leaks

-- Operate the hand pump multiple times to acquire a pressure of 3.0 bar (43.51 psi).

-- Watch the pressure at the pressure gauge from the cooling system tester for 30 seconds.

If there is no pressure built up or if it drops afterwards, the cooling system tester may not be used.
