1. Check the cooling system for leaks
• Remove the original cover from the radiator or expansion tank.
• Select the appropriate adapter from the test kit and connect it to the radiator or expansion
tank.
• Then connect the pump (1) to the adapter.
• Operate the test pump until a pressure of 10 to 15 psi is reached. (see fi g. 1+2).
CAUTION : Avoid a pressure of 35 psi or more!
Check the pressure gauge. If the displayed value drops, the cooling system leaks. Leaks are
manifested by a pressure drop and water exiting at the leak site.
2. Check the radiator cover for leaks
• Remove the original radiator cover
• Choose the connection element (30 or 31) plus the appropriate plug to connect the pump
to the connection element. Connect the existing original radiator cover to the connection
element so that it is mounted as shown in fi g. 3.
• Turn on the test pump several times and observe the pressure gauge to detect a possible
leak.
• Compare the measured pressure with the standard pressure values of the radiator cover
MAINTENANCE/STORAGE
• Connect the hand pump to the adapter. Operate the hand pump several times, this allows the
residual coolant to drain from the adapter.
• Pour a few drops of oil into the hand pump through the fi tting to lubricate the piston.
IMPORTANT !
