UView Combustion Leak Tester - Manual

Combustion gas, when it enters the cooling system through any leak, accumulates in the air
cushion above the radiator coolant level (in sealed coolant systems, this air cushion must be
created by lowering the coolant level about an inch and a half). The Leak Tester analyzes
this air: The blue fluid turns yellow when CO
2
gas is detected in gasoline engines and green in
diesel engines. The double-chamber feature of the Leak Tester assures a high level of accuracy.
Conventional detection methods often give incorrect readings because alkaline particles present in the
air cushion can cause false indications of a combustion leak. Alkaline particles are absorbed by the
Leak Tester's first chamber, which acts as a filter, allowing only air and CO
2
to reach the second,
upper chamber. If the blue fluid in this upper chamber turns yellow or green, it is proof positive that
there is a combustion gas (CO
2
) leak into the coolant.
Pull the three segments apart using a firm, twisting motion. Fill each of the two chambers up to the
fill line (1/2 oz.) with fresh blue Leak Tester fluid and reassemble, while keeping the hole in the rubber
intake end plugged with a finger. The fluid is not hazardous: it is non-toxic, non-flammable and
contains no acid. It will stain clothes. Stains should be washed immediately and not allowed to dry.
(CAUTION: The fluid may irritate skin and eyes; affected areas should be washed thoroughly with tap
water immediately after contact).
Test the tool and fluid by exhaling into a cupped hand and sucking the exhaled air through the intake
hole into the two chambers by squeezing the rubber bulb two or three times, holding the Leak Tester
in a vertical position. (CAUTION: Do not put the rubber intake end in your mouth).
Do not use exhaust gasses or smoke from cigarettes or matches, etc... for this test, as this could
contaminate the test fluid. If the fluid fails to turn yellow or green it should be replaced and the
chambers washed thoroughly with clean water.
IMPORTANT: Do not wipe dry. Do not use soap or detergent, as these can contaminate the fluid.
There are two basic types of tests that can be performed: The “routine maintenance” test and the
“major leak” test. Always start with the “routine maintenance” procedure. The “major leak” test is
required only when a leak is detected. Because of the high sensitivity of the Leak Tester fluid, even
the smallest leak can be detected, even hours after it has occurred. The “routine maintenance” test
can be performed with the engine running or just after it has been turned off.
Store the Leak Tester fluid at room temperature. Both fluid and chambers must be kept clean.
If the fluid becomes contaminated or fails the sensitivity test (see above) it must be discarded
and replaced with fresh fluid after the chambers have been thoroughly cleaned with fresh water.
COMBUSTION LEAK TESTER INSTRUCTIONS
Designed to check for leaks between Combustion Chamber and
Cooling System of water-cooled engines.
WARNING!
Hot coolant can cause severe burns.
• Pressurized system can leak.
Wear safety goggles (user and bystanders).
Use in well ventilated area.
Do not breathe coolant vapors.
Read and follow instructions.
Pressurized leaks and breathing vapors can cause injury.
• Hot antifreeze/coolant under pressure.
Wear safety shield and protective
clothing (user and bystanders).
Do not open system when hot.
Hot, pressurized antifreeze/coolant
can cause injury.
Keep self and tools clear of
moving parts.
Moving components can cause injury.
