MAINTENANCE
•
In case of an unintentional suction of coolant, clean the tester with washing up liquid and rinse with
water.
•
Dry the tester before refilling with new contrast agent.
•
Never use bases, soaps or paint thinner for cleaning.
INSTRUCTION
1 Preparation
Bleed the coolant up to 3 - 4 cm under the filler hole. This way, there won't be any
coolant sucked in unintentionally while testing. Keep in mind that the air cushion is
not too big, so that small amounts of combustion gases can be detected, too.
Carefully remove any residual gases in the air cushion by using compressed air.
Small amounts of combustion gases accumulate in the air cushion after a longer
period of time. Do not 'blow' with your mouth - the CO² in your breath causes a
change of color to yellow and therefore causes an incorrect testing result. Close
the cooling system, again.
2 Filling contrast agent
Fill test fluid into the upper and lower housing, up to the mark.
3 Preparation for test with vehicle-specific adapter
Dismantle rubber cone by pulling.
Install the terminal for vehicle-specific adapter.
Secure the plug-in connection with upper knurled threaded sleeve.
4 Testing with/without vehicle specific adaptor
After a short test drive, fit the tester into the filler hole and accelerate
impulsively a few times to create the highest level of combustion pressure
possible. Activate the suction ball several times (10 - 15 times). A test with
a vehicle specific adaptor responds more accurate, since it provides a
100% sealing from outside air.
Caution: The cooling system is under pressure, when engine is running
and the coolant is hot.
5 Test without the suction ball
Procedure as described above, but with activating the suction ball. The air cushion gets
pushed through the tester by the cooling system.
6 Analysis
• If the contrast agent changes color after the test, there is a leakage. A possible cause
could be a crack in the cylinder head, a broken cylinder head gasket etc.
• If there is no visible change of color, there is no leakage in the section between
combustion chamber and cooling system.
Run steps 1-3 of chapter "CONTRAST AGENT" after each test.
