1.Remove the original radiator cap while the engine is cold 2. Choose an test cap suiting the connection type onto the radiator
.Screw the cap onto the radiator opening 3. Connect the pump to the test cap through the quick coupling at the hose end 4.Pump
until pressure is approximately 10-15 psi. If the gauge pointer does not move for approximately 1 minute, the, whole circuit is
perfectly efficient if it goes down, the circuit leaks, where water is discharged. If the gauge goes down and no fluid discharges

release pressure through the button next to the quick coupling and put away the device, after removing any fluid or dirt
