Engine Lubrication: Testing and Inspection

ON-VEHICLE INSPECTION
1. CHECK ENGINE OIL LEVEL
(a) Warm up the engine, stop the engine and wait for 5 minutes.
(b) Check that the engine oil level is between the L and F marks of the oil dipstick.
If low, check for leakage and add oil up to the F mark.

NOTICE: Do not add engine oil above the F mark.





2. CHECK ENGINE OIL QUALITY
(a) Check the oil for deterioration, water intrusion, discoloration or thinning.
If the quality is visibly poor, replace the oil.
Oil grade: Use ILSAC multigrade engine oil. SAE 5W-20 and SAE 0W-20 engine oil may be used. However, SAE 0W-20 is the best choice for good fuel economy and good starting in cold weather.
3. CHECK OIL PRESSURE
(a) Disconnect the oil pressure switch connector.





(b) Using a 24 mm deep socket wrench, remove the oil pressure switch.





(c) Install the oil pressure gauge.
(d) Warm up the engine.
(e) Measure the oil pressure.

Standard Oil Pressure:

(f) Apply adhesive to 2 or 3 threads of the oil pressure switch.
Adhesive: Toyota Genuine Adhesive 1344, Three Bond 1344 or Equivalent
(g) Using a 24 mm deep socket wrench, install the oil pressure switch.
Torque: 15 Nm (153 kgf-cm, 11 ft. lbs.)

NOTICE: Do not start the engine within 1 hour of installation.

(h) Connect the oil pressure switch connector.
