LEAKAGE TEST USING SMOKE TEST EQUIPMENT
| CAUTION | The compressed air line supply pressure must be between 3.5 and 12 bar (50 and 175 psi) for the smoke test equipment to function correctly. Do not exceed this pressure. Failure to follow this instruction may result in damage to the smoke test equipment. |
Note. The vehicle battery must be in good condition and fully charged before carrying out this procedure.
Note. On vehicles with 3.0L TDV6, it will be necessary to insert smoke at both air cleaner outlet pipes independently if the right hand turbocharger and associated hoses are to be tested.
Note. In some cases it may be necessary to remove undertrays, trim or engine covers to obtain access to all potential leak locations.
Note. Some variation in the illustrations may occur, but the essential information is always correct.
Note. For further information regarding operation of the test equipment refer to the manufacturers operators information supplied with the kit.
