Precaution for Liquid Gasket

INFOID:0000000003304242

LIQUID GASKET APPLICATION PROCEDURE

Remove old liquid gasket adhering to the liquid gasket application surface and the mating surface.
• Remove liquid gasket completely from the liquid gasket application surface, mounting bolts, and bolt

holes.

Wipe the liquid gasket application surface and the mating surface with white gasoline (lighting and heating
use) to remove adhering moisture, grease and foreign materials.

Apply liquid gasket to the liquid gasket application surface.
Use Genuine RTV Silicone Sealant or equivalent. Refer to

GI-17, "Recommended Chemical Prod-

ucts and Sealants"

• Within 5 minutes of liquid gasket application, install in the mating component.
• If liquid gasket protrudes, wipe it off immediately.
• Never retighten mounting bolts or nuts after the installation.
• After 30 minutes or more have passed from the installation, fill engine oil and engine coolant.

Inspection

INFOID:0000000003304245

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 check 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.

ENGINE OIL LEAKAGE

Check for engine oil leakage around the following areas:
• Oil pans (lower and upper)
• Oil pan drain plug
• Oil pressure switch
• Oil temperature sensor
• Oil filter
• Water pump cover
• Oil cooler
• Valve timing control covers (bank 1 and bank 2)
• Intake valve timing control solenoid valve (bank 1 and bank 2)
• Mating surface between cylinder head and rocker cover
• Mating surface between front timing chain case and rear timing chain case
• Mating surface between rear timing chain case and cylinder head
• Mating surface between rear timing chain case and cylinder block
• Mating surface between rear timing chain case and oil pan (upper)
• Mating surface between cylinder block and cylinder head
• Crankshaft oil seals (front and rear)
• Camshaft position sensor (PHASE)

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-7, "Inspection"

Remove splash guard (RH). Refer to

ENGINE OIL

Disconnect harness connector at oil pressure switch (2), and
remove oil pressure switch using deep socket (commercial ser-
vice tool).

CAUTION:

Never drop or shock oil pressure switch.

Install the oil pressure gauge [SST: ST25051001 (J-25695-1)]
(A) and hose [SST: ST25052000 (J-25695-2)] (B).

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.

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

After the inspections, install oil pressure switch as follows:

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

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

GI-17, "Recommended Chemical Prod-

ucts and Sealants"

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

Draining

INFOID:0000000003304246

WARNING:

• Be careful not to get burn yourself, as engine oil may be hot.
• Prolonged and repeated contact with used engine oil may cause skin cancer. Try to avoid direct skin

contact with used engine oil. If skin contact is made, wash thoroughly with soap or hand cleaner as
soon as possible.

Warm up the engine, and check for engine oil leakage from engine components. Refer to

LU-7, "Inspec-

tion"

Stop the engine and wait for 10 minutes.

Loosen oil filler cap.

CAUTION:

• When filling engine oil, never 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.
