INSTRUCTIONS
Step #1 PREPARE THE VEHICLE THAT IS TO BE TESTED
• Drain some of the antifreeze out of the radiator until the water level is approximately 1-1/2 inches below the fill neck
of the radiator.
• NOTE: ANTI-FREEZE SHOULD NOT BE ALLOWED INTO THE LEAK TEST TOOL. If this happens, stop the test when the
coolant reaches the red line
• NOTE: This step is necessary to provide a void in
the top of the radiator for CO2 to accumulate.
Step #2 PREPARE THE TOOL FOR TESTING
• Remove the cap from the top of the test
chamber.
• Pour the test fluid into the top chamber to the
line marked, "CO2 leak detector."
• NOTE: Keep the bottle of test fluid capped to
reduce the risk of contamination
• Install the cap onto the top test chamber.
• Attach the rubber bulb pump to the cap on the
top of the test chamber.
Step #3 TEST THE VEHICLE (fig. 1)
• Start the car.
