RADIATOR/HEADER TANK ADAPTOR CONFIGURATION.
3.2.1
As shown in fig.2a the tester can be configured to fit onto a header tank or radiator using one of the adaptors supplied with the VS006
pressure test kit. See fig.2b. When the tube on the lower chamber ‘D’ is inserted into the brass adaptor ‘E’ ensure that the brass ring
at the top of the adaptor is tightened down so that it grips the tube. The brass adaptor ‘E’ will be a push fit onto the radiator or header
tank adaptor. Push down until it clicks into place. To release the assembly pull the ring at the bottom of the brass adaptor upwards.
3.2.2
Fill the upper chamber with test fluid up to the dotted line.
3.2.3
Turn on the vehicle engine and wait for steam to enter the lower chamber.
3.2.4
When steam is visible in the lower chamber pump the rubber bulb several times to draw steam into the upper chamber and observe
the colour of the test fluid. If the fluid turns yellow this indicates the presence of CO
for a suspect cylinder head gasket or cracked head.
3.2.5
Alternatively the tester can be used without the bulb attached as shown in fig.2c. In this configuration the steam will automatically pass
into the upper chamber. Take care to keep limbs and face away from any jet of steam being expelled from the hole in the top of the cap.
3.2.6
As soon as the test is complete turn off the engine and allow the sytem to cool for a while. Before removing the tester from the
radiator or header tank open the tap on component ‘E’ to allow any remaining pressurised steam to escape. Thick gloves must be
worn during this process and when the tester and adaptor are removed from the radiator.
3.2.7
Remove the upper chamber from the lower chamber by twisting them apart. Pump the bulb several times to draw fresh air into the
chamber. When the air mixes with the test fluid it should return to a blue colour and can be retained for future use. See fig.1b.
3.3.
HAND-HELD CONE CONFIGURATION.
3.3.1
Where no adaptor is available a rubber cone can be fitted to the bottom of the tester as shown in fig.3a. This allows the tester to be
held in place on a header tank (see fig.3b) or radiator opening (see fig.3c).
WARNING! Thick protective gloves must be worn when using the tester in this configuration to protect the operator from any escaping
p
p
steam. Great care should be taken when placing the adaptor over the radiator or header tank opening and also when removing it.
3.3.2
Fill the upper chamber with test fluid up to the dotted line.
3.3.3
Remove the radiator or header tank cap. Turn on the vehicle engine and wait for steam to appear. Place the tester onto the radiator or
header tank opening and hold it down and steady so that it makes an effective seal against the opening.
3.3.4
As soon as steam appears in the lower chamber pump the bulb to draw the steam into the upper chamber and observe the colour of
the test fluid. If the fluid turns yellow this indicates the presence of CO
cylinder head gasket or cracked head.
3.3.5
As soon as the test is complete remove the tester from the radiator opening and turn the engine off. When there is no more steam
emanating from the opening replace the cap.
3.3.6
Remove the upper chamber from the lower chamber by twisting them apart. Pump the bulb several times to draw fresh air into the
chamber. When the air mixes with the test fluid it should return to a blue colour and can be retained for future use. See fig.1b.
