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 10 minutes before checking.

Pull out oil level gauge and wipe it clean.

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

If it is out of range, adjust it.

ENGINE OIL APPEARANCE

●

Check engine oil for white turbidity or heavy contamination.

●

If engine oil becomes turbid and white, it is highly probable that it is contaminated with engine coolant.
Repair or replace damaged parts.

●

Oil pans (lower and upper)

●

Oil pan drain plug

●

Oil pressure switch

●

OIL PRESSURE CHECK

WARNING:

●

Be careful not to get burn yourself, as engine oil may be hot.

●

Oil pressure check should be done in “Parking position”.

Check the engine oil level. Refer to

LU-6, "ENGINE OIL LEVEL"

Remove splash guard (RH).

Disconnect harness connector at oil pressure switch, and
remove oil pressure switch using deep socket (commercial ser-
vice tool)

CAUTION:

Do not drop or shock oil pressure switch.

Install pressure gauge (SST) and hose (SST).

Start the engine and warm it up to normal operating temperature.

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

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

Engine oil pressure [Engine oil temperature at 80

C (176

F)]

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

After the inspections, install oil pressure switch as follows:

Remove old liquid gasket adhering to oil pressure switch and mating surface.

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

GI-46, "RECOMMENDED CHEMICAL

PRODUCTS AND SEALANTS"

After warming up the engine, check for oil leakage with running engine.

CAUTION:

●

When filling engine oil, do not pull out oil level gauge.

●

The refill capacity depends on the engine oil temperature and drain time. Use these specifica-
tions for reference only.

●

Always use oil level gauge to determine the proper amount of engine oil in engine.

engine oil leakage or spillage.

●

Do not allow engine oil to adhere to drive belts.

●

Completely wipe off any engine oil that adheres to engine
and vehicle.

INSTALLATION

Remove foreign materials adhering to oil filter installation surface.

Apply engine oil to the oil seal contact surface of new oil filter.

Screw oil filter manually until it touches the installation surface,
then tighten it by 2/3 turn. Or tighten to the specification.

INSPECTION AFTER INSTALLATION

Check the engine oil level. Refer to

LU-6, "ENGINE OIL"

Start engine, and check there is no leak of engine oil.

Stop engine and wait for 10 minutes.
