CAUTION:
To prevent injury due to contact with an operating fan and generator V-belt or cooling fan, keep your hands and clothing away from the fan and generator V-belt and cooling fans when working in the engine compartment with the engine running.
To prevent burns, do not touch the engine, exhaust manifold or other high temperature components while the engine is hot.
To prevent burns, do not remove the engine oil pressure switch assembly while the engine is hot.
PROCEDURE
CHECK ENGINE OIL QUALITY
Check the oil for deterioration, water contamination, discoloration or thinning.
If the quality is visibly poor, replace the engine oil and oil filter sub-assembly.
CHECK ENGINE OIL LEVEL
Warm up the engine and then wait for 5 minutes after turning the engine off. The oil level should be between the low level and full level marks of the engine oil level dipstick.
If low, check for leakage and add oil up to the full level mark.
Note
Do not add engine oil above the full level mark.
INSPECT OIL PRESSURE

| *a | Oil Pressure Gauge |
Install an oil pressure gauge.
Warm up the engine.
Measure the oil pressure.
| Condition | Specified Condition |
|---|---|
| Idling | 29 kPa (0.3 kgf/cm2, 4.2 psi) or higher |
| 3000 rpm | 294 to 539 kPa (3.0 to 5.5 kgf/cm2, 43 to 78 psi) |
If the result is not as specified, check the oil pump.
Remove the oil pressure gauge.
Install the engine oil pressure switch assembly.
