temperature.

2. Disconnect the negative battery cable.

3. Remove the spark plugs.

4. Check the coolant level by opening the coolant

reservoir cap and replenish if insufficient.

5. Open the engine oil filler cap.

6. Connect the tester to air pressure line and adjust

the scale of tester.

7. Install the connecting hose to spark plug hole.

9. Connect the connecting hose to tester and

measure the leakage volume after blowing up
5 bar of compressed air.

Notice: Measure the leakage volume in the
completely opening condition of throttle valve by
pulling the acceleration cable.

10. Perform the pressure test according to the firing

order.

Notice:

Firing Order

•

M162 Engine: 1 - 5 - 3 - 6 - 2 - 4

Leakage Test

1. Run the engine to be the coolant temperature

80 °C (176 °F).

2. Remove the fuel injection nozzle.

3. Open the coolant reservoir.

4. Check the coolant level and replenish if necessary.

5. Open the oil filler cap.

6. Remove the air cleaner cover and element.

7. Position the piston at TDC.

8. Install the connector (1) and connection piece (2).

9. Calibrate the tester and connect the connection

hose (3)

10. Pressurize with compressed air and compare the

pressure changes with permissible pressure
leakage.

11. If permissible pressure leakage is out of standard,

check followings :

- Intake and exhaust lines.

- Sounds in oil filler area.

- Air bubbles in radiator coolant.

12. Do pressure leakage test for the remaining

cylinders according to the firing order.

•

firing order: 1-2-4-5-3

13 . Remove the tester.

14 . Close the coolant reservoir cap and oil filler cap.

15 . Install the air cleaner element and cover.

16 . Install the fuel injection nozzle.
