CAUTION: For the smoke leak testing equipment to operate correctly, the compressed air supply line pressure must be between 3.5 and 12 bar (50-175 psi). The maximum pressure must not be exceeded. Failure to do so may result in damage to the smoke leak test equipment.
NOTE: Before performing this procedure, make sure the vehicle battery is fully charged and serviceable.
NOTE: On vehicles with the 3.0L TDV6 engine, it is necessary to inject smoke into both air cleaner outlets regardless of whether the right turbocharger and associated hoses are being tested.
NOTE: In some cases it may be necessary to remove the oil pans, trim panels or engine cover to gain access to all potential leak locations.
NOTE: Illustrations may differ in some details, but the fundamental points are completely true.
NOTE: For more detailed information on the operation of the smoke leak testing equipment, please refer to the operating manual provided by the equipment manufacturer and supplied with the equipment.
1.
WARNING: If the smoke leak test equipment is attached to the hood, use additional support to prevent the hood from falling. Failure to do so may result in personal injury.
Install the smoke leak test equipment in the appropriate location under the hood.
2. Connect the appropriate compressed air supply line to the smoke leak testing equipment.
3. Connect the positive power lead of the smoke leak test equipment to the positive terminal of the battery.
4.
WARNING: Do not connect the negative lead of the smoke test equipment to the negative terminal of the battery.
Connect the negative lead of the smoke leak test equipment to a suitable ground point on the vehicle body.
5.
NOTE: A flashing green light indicates that the battery voltage is low. In this case, put the battery on charge and make sure the battery is fully charged before using the smoke leak test equipment.
Observe the power LED indicator on the smoke leak test equipment. Make sure the indicator is green all the time.
6.
NOTE: In some cases it may be necessary to remove the air filter(s) to gain access to the air filter outlets.
NOTE: In some cases it may be necessary to plug one of the air cleaner outlets. Use the plugs provided to plug the opening.
Disconnect the air cleaner outlet pipe(s).
7.
NOTE: Make sure the smoke leak test equipment adapter is securely connected to the air cleaner outlet. This connection should be airtight.
Connect the supply hose of the smoke leak test equipment to the air cleaner outlet.
- 1. Install the appropriate adapter onto the air cleaner outlet pipe.
- 2. Connect the supply hose of the smoke leak test equipment to the connecting hose of the adapter.
8.
NOTE: The flow regulator must be in the fully open position.
NOTE: Smoke is generated for 5 minutes. The smoke leak test equipment will automatically shut off after this time.
Turn on the smoke leak testing equipment.
9. Remove the oil filler cap and wait until a continuous stream of smoke comes out of the oil filler hole. Install the oil filler cap.
10.
NOTE: The longer smoke comes out of the leak, the more the leak will become colored with fluorescent dye.
Use the included flashlight to inspect the escaping smoke by shining a white light on it. Alternatively, use an ultraviolet lamp to look for deposits of fluorescent dye at the leak.
