Checking Engine Oil Pressure on Petrol Models
1. Remove the engine trim panels/air cleaner assembly by pulling straight up.
2. Remove the cooling system fan assembly (8) and its casing (9).
3. Unscrew the threaded plug (4) from the timing belt cover and remove it together with the sealing washer (5).
Note: The sealing washer must be replaced.
4. Using a two-way nipple connector (2) seated in the timing drive cover on the sealing washer (3), connect a pressure gauge (1) equipped with a connecting hose to the engine to measure the oil pressure.
5. Check the engine oil level and make adjustments if necessary (see Chapter Routine care and maintenance).
6. Remove the dipstick (7) for measuring the engine oil level from the guide tube and replace it with the remote thermometer (6).
7. Start the engine, warm it up to normal operating temperature (80°C), then read the pressure gauge readings at different crankshaft speeds. Compare the measurement results with the requirements Specifications.
Note: When you press the gas pedal, the pressure should increase instantly.
8. Installation is carried out in reverse order.
Diesel models (M612)
Checking engine oil pressure on diesel models (M612)
1. Remove the upper trim panels from the cylinder head cover.
2. Then proceed according to the instructions given in paragraphs 4 through 8 (for Petrol models).
Note: Readings are taken at an operating oil temperature of 90°C. At idle speed, the oil pressure should not fall below 0.3 atm (bar); when you press the gas pedal, the reading should instantly increase, reaching a value of at least 3 atm (bar) at 3000 rpm.
