Oil level and contamination
Before starting the engine, check the oil level with the vehicle level. If you have already started the engine, stop it and wait 10 minutes before proceeding with the test.
Make sure the oil level is within the range shown in the figure.
If it is outside this range, bring it up to normal.
Check for white cloudiness or significant contamination in the oil.
If the oil becomes cloudy and white, it is highly likely that engine coolant has entered the oil. Find the cause and fix it.
While inserting the dipstick into the guide, apply oil to the handle rubber seal.
Oil leak
Check for oil leaks around the following areas:
- oil pan (upper and lower);
- Oil pan drain plug;
- The switch of a control lamp of low pressure of oil;
- Oil filter;
- The electrovalve of the mechanism for regulating the valve timing of the intake valves;
- Contact surface between cylinder block and cylinder head;
- Contact surface between cylinder head and valve cover;
- Crankshaft oil seals (front and rear);
- Oil filter (for the solenoid valve of the intake valve timing mechanism).
Oil pressure check
Attention:
- Do not burn yourself with hot engine oil.
- Oil pressure should be checked in neutral position. Apply the parking brake firmly.
1. Check the oil level. See above «Oil level and contamination».
2. Turn out the oil filter. See section «Oil filter».
3. Disconnect the connector from the low oil pressure warning light switch and unscrew it with a long socket (suitable special tool).
1. Cylinder block
2. Low oil pressure warning light switch
3. Oil level sensor
4. Connect oil pressure gauge and hose (special tool).
5. Screw in the oil filter. See section «Oil filter».
6. Check the oil level. See above «Oil level and contamination».
7. Start the engine and warm it up to normal operating temperature.
8. Check the oil pressure with the engine running at no load.
Note: When the engine oil temperature is low, the oil pressure increases.
Engine oil pressure (oil temperature 80°C)
Engine speed (rpm) | Approximate outlet pressure, kPa (kg/cm2) |
Turnover frequency x.x. | Over 60 (0,61) |
2000 | Over 275 (2,8) |
If the pressure is significantly different from the specified, check for oil leakage in the engine oil passage and oil pump.
9. After completing the test, screw the low oil pressure warning light switch back into place as follows:
- A. Unscrew the oil filter. See section «Oil filter».
- b. Remove the old sealant from the switch and from the mounting hole on the motor.
- With. Apply sealant and tighten the switch to the correct torque.
Use branded sealant or equivalent.
Tightening torque: 19.6 Nm (2.0 kg m)
- d. Screw in the oil filter. See section «Oil filter».
- e. Check the oil level. See above «Oil level and contamination».
- f. Warm up the engine and check for oil leaks with the engine running.
