Examination
1. Check the engine oil level, refer to Section Checking fluid levels, leak control.
2. Warm up the engine to operating temperature. To do this, start the engine and wait until the normal coolant temperature appears on the dashboard. To do this, turn on the coolant temperature indicator on the dashboard display. Then drive the vehicle for approximately 5 km to ensure that the engine oil reaches its operating temperature.
Note. At the service station, the oil temperature is checked by inserting a thermometer into the hole of the oil level indicator. The set value is + 90°C.
3. Oil pressure is measured at the oil filter cap. This requires a special filter cap (special tool) with pressure gauge connection.
- A replacement oil filter cap is required.
The cover can be made as follows:
4. Drill a hole with a diameter of 8 mm in the center of the cover.
5. Drill a 2 mm hole in the M6 hexagon socket screw.
6. Cut the M6 thread in the M12 x 1.5 hose connection.
7. Insert a screw with a 6.5 x 18 sealing washer from the inside into the hole in the oil filter cover.
8. Install the 12 x 17 aluminum o-ring and hose fitting on the outside of the cover. Screw a hexagon socket screw into the connection fitting.
9. 4-cylinder petrol engine: Unscrew the oil filter cap using a 74mm socket or HAZET 2169.
10. Take out the cover with the filter element (2). (3) - sealing ring.
11. Diesel engine: Remove the oil filter cap (1) with HAZET 2169 tool (2) and 27 mm heads (3). The illustration shows the 611 engine.
12. Insert a new filter element into the oil filter housing.
13. Screw on the cap with the connection to check (special tool) and sealing ring.
14. Attach a manometer to check the oil pressure to the hose fitting.
15. Start the engine and let it idle.
16. Oil pressure should not be less than 0.3 atm. Otherwise, check the lubrication system (pump, bearings, etc.).
17. With an increase in engine power, the oil pressure should immediately increase and at 3000 rpm the engine should be at least 3 atm.
18. Stop the engine.
19. Turn out the manometer.
20. After completing the oil pressure check, install the original oil filter cap with a new O-ring.
6-cylinder petrol engine 112
1. Oil pressure is checked at the measuring hole on the end side of the engine.
2. Remove the engine cover or air filter vertically upwards.
3. Remove the cover of the fan with an electric motor, refer to Section Removal and installation of the fan.
4. Remove the oil pressure gauge screw plug located at the bottom of the oil filter housing on the distributor housing.
5. Screw in the screw plug with a new sealing ring and tighten it to 20 Nm.
6. Install the cover with the electric fan.
7. Install the engine cover or air filter on top.
