CAUTION / NOTICE / HINT
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
INSPECT OIL QUALITY
Check the engine oil for deterioration, water contamination, discoloration or thinning.
If the quality is visibly poor, replace the engine oil and oil filter sub-assembly.
INSPECT ENGINE OIL LEVEL
Warm up the engine, stop the engine and wait 5 minutes. The engine oil level should be between the engine oil level dipstick low level mark and full level mark.
If low, check for leakage and add oil up to the full level mark.
Note
Do not fill engine oil above the full level mark.
Tech Tips
A certain amount of engine oil will be consumed while driving. In the following situations, oil consumption may increase, and engine oil may need to be refilled in between oil maintenance intervals.
When the engine is new, for example directly after purchasing the vehicle or after replacing the engine.
If low quality oil or oil of an inappropriate viscosity is used.
When driving at a high engine speed or with a heavy load, when towing, or when driving while accelerating or decelerating frequently.
When idling for a long time, or when driving frequently through heavy traffic.
When judging the amount of oil consumption, keep in mind that the oil may have become diluted, making it difficult to judge the true level accurately.
INSPECT ENGINE OIL PRESSURE
Remove the engine oil pressure switch assembly.

Install an oil pressure gauge with an adapter.
Warm up the engine.
Measure the engine oil pressure.

If the pressure is not as specified, check the oil pump.
Remove the oil pressure gauge and adapter.
Install the engine oil pressure switch assembly.
