ON-VEHICLE INSPECTION
1. CHECK ENGINE OIL LEVEL
(a) Warm up the engine, then stop the engine and wait for 5 minutes.
(b) Check that the engine oil level is between the low and full level marks on the level gage.
If low, check for leakage and add oil up to the full level mark.
NOTICE:
Do not fill with engine oil above the full level mark.
2. CHECK ENGINE OIL QUALITY
(a) Check the oil for deterioration, water intrusion, discoloring
or thinning.
If the quality is visibly poor, replace the oil.
Oil grade:
Use API grade SL ºEnergy-Conservingº, or ILSAC
multigrade engine oil.
SAE 5W-30 is the best choice for good fuel economy,
and good starting in cold weather.
If SAE 5W-30 is not available, SAE 10W-30 may be
used.
However, it should be replaced with SAE 5W-30 at the
next oil replacement.
3. INSPECT OIL PRESSURE
(a) Disconnect the oil pressure switch connector.
(b) Using a deep socket wrench 24 mm, remove the oil pres-
sure switch.
(c) Install the oil pressure gauge.
(d) Warm up the engine.
(e) Inspect the oil pressure.
Oil pressure:
At idle29 kPa (0.3 kgf/cm2, 4.3 psi) or more
At 3,000 rpm245 to 539 kPa (2.5 to 5.5 kgf/cm2, 36 to 78 psi)
