ENGINE OIL LEVEL

NOTE:
Before starting engine, put vehicle horizontally and check the engine oil level. If engine is already started, stop
it and allow 15 minutes before checking.

1.

Pull out oil level gauge and wipe it clean.

2.

Insert oil level gauge and make sure the engine oil level is within
the range shown in the figure.

3.

If it is out of range, adjust it.

ENGINE OIL APPEARANCE

Check engine oil for white turbidity or heavy contamination.

4.

Install oil pressure gauge and hose (SST).

5.

Start engine and warm it up to normal operating temperature.

6.

Check the engine oil pressure with engine running under no-load.

NOTE:
When engine oil temperature is low, engine oil pressure becomes high.

Engine oil pressure [Engine oil temperature at 80

°

C (176

°

F)]

Unit: kPa (kg/cm

2

 , psi)

If difference is extreme, check oil passage and oil pump for oil leaks.

7.

After the inspections, install oil pressure switch as follows:

a.

Remove old liquid gasket adhering to oil pressure switch and engine.

b.

Apply liquid gasket and tighten oil pressure switch to the specification.
Use Genuine RTV Silicone Sealant or equivalent. Refer to 

GI-47, "RECOMMENDED CHEMICAL

PRODUCTS AND SEALANTS"

 .

c.

After warming up engine, make sure there is no leakage of engine oil with running engine.
