• 1.) Acrylic Cuboid.
• 2.) Rubber Bulb.
• 3.) Cone-Shaped Adapter.
• 4.) Tester Fluid.

• If exhaust gasses presents in cooling system,the color of test liquid turns from
  blue to green or yellow.
• If the detector liquid still in blue during test operating, it means the gasket keeps

• Step 1: Prepare a container and remove the approximately 1/10 of the volume of coolant
               from the radiator. (fig. 1)
• Step 2: Open the cap of chamber No.2, fill it with blue test CO2 liquid till HALF of the
               chamber NO.2
• Step 3-1: Test with universal rubber rediator adaptor: Install the rubber bulb on chamber
                  No. 2 and then connect universal rubber radiator adaptor (4) with quick adaptor.
                  Then, install the whole test device on the opening of radiator. (fig.2)
• Step 3-2: Alternative test way with suitable radiator test adaptor: Install the rubber bulb on
                  chamber No. 2 and then connect test radiator adaptor with quick adaptor. Then,
                  install the whole test device on the opening of radiator. (fig.3)
• Step 4: Start the engine; the steam from radiator into test chamber and mix with test liquid
               in chamber No.2.
