4. Precaution.
INSTRUCTION
1. The vehicle must be cold. If the cooling system is
hot, do not attempt to remove the header tank cap or
radiator cap. Wait until it cools down.
2. Install the rubber bulb, the cap, the upper chamber,
the lower chamber, brass adaptor and also the rubber
cone that allows the leak detector to be held in pla-
ce on a header tank or radiator opening. And then, fill
up the upper chamber with blue detector liquid till the
black line.
3. Squeeze the rubber bulb completely and slowly
about 3-5 times for gasoline (form 5 to 10 times for
diesel), sucking the air up through the two fluid-filled
chambers. As the air bubbles up through the fluid, it will
cause a chemical reaction if combustion gas is present
which Will change the colour of the blue fluid to yellow
for gasoline (green for diesel).
4. If the fluid turns into green/yellow, it indicates the
presence of CO2 in the coolant and the need to inves-
tigate further.
5. Remove the leak detector and turn the engine off.
6. With the engine off and the radiator cap open, fill the
radiator with coolant to the top of the filler neck.
7. Dismantle the upper chamber from the lower cham-
ber by twisting them apart. Pump the rubber bulb seve-
ral times to draw fresh air through the test fluid. When
it has returned to its original blue colour, it can be retur-
ned to the container and used.
CO2 COMBUSTION LEAK DETECTOR
This tool is designed to check for the
leaks between combustion and cooling
system of water-cooled engines.
Combustion process produces (beside
others) 13-14% CO2 in the exhaust and
the leakage of this gas in the cooling
system is easily detected.
If there are combustion gases, the co-
lour of the test fluid in the upper cham-
ber turns yellow or green, it means com-
bustion gas (CO2) leak into the coolant.
Test fluid is reusable (refer to the ins-
truction).
TROUBLE SHOOTING
1. Dismantle the container following the next order:
ATTENTION: The tube #2 has to be handled with pliers
very carefully so it won't break.
2. Remove the rubber valve #1. Installation must be
carried out in the reverse order of disassembly.
Pay special attention at the assembly of rubber valve
#1 and tube #2, NOT FULLY PUSHED IN.
ATTENTION: Excessive pressure on the rubber valve
#1 and on the tube #2 is the main reason for the lack
of pressure.
PRECAUTION
ADVERTENCIA!
1. The hot coolant may cause severe burns.
2. Do not open the radiator cap before ensuring the
temperature is low.
3. Protect your hand and eyes, always.
4. Do not breathe coolant vapors.
5. Dismantle, clean and dry the detector components
after each use.
The supplier is not responsible for any damage result
of a missuse or improper use of the tool provided.
