PRECAUTIONS PFP:00001

Precautions for Liquid Gasket EBS011WG

LIQUID GASKET APPLICATION PROCEDURE
1. Remove old liquid gasket adhering to the liquid gasket application surface and the mating surface.
q Remove liquid gasket completely from the liquid gasket application surface, mounting bolts, and bolt
holes.
2. 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.
3. Attach liquid gasket tube to tube presser (SST).
Use Genuine RTV Silicone Sealant or equivalent. Refer to
GI-46, "RECOMMENDED CHEMICAL PRODUCTS AND
SEALANTS" .
q Within five minutes of liquid gasket application, install the mat-
ing component.
q If liquid gasket protrudes, wipe it off immediately.

q Do not retighten mounting bolts or nuts after the installation.

q After 30 minutes or more have passed from the installation, fill
engine oil and engine coolant. PBIC2160E

Inspection EBS0024U

ENGINE OIL LEVEL
NOTE:
Before starting engine, check the oil level. If engine is already started, stop it and allow 15 minutes before
checking.
1. Put vehicle horizontally.
2. Pull out oil level gauge and wipe it clean.
3. Insert oil level gauge and check that the engine oil level is within
the range shown in the figure.
4. If it is out of range, adjust it.

PBIC0801E

ENGINE OIL APPEARANCE
q Check engine oil for a white milky appearance or excessive contamination.
q If engine oil is milky, it is highly probable that it is contaminated with engine coolant. Repair the broken
parts.
ENGINE OIL LEAKAGE
Check for engine oil leakage around the following area.
q Oil pan
q Oil pan drain plug
q Oil pressure switch
q Oil filter
q Intake valve timing control cover
q Intake valve timing control solenoid valve
q Front cover
q Mating surface between cylinder block and cylinder head
q Mating surface between cylinder head and rocker cover
q Crank oil seal (front and rear)
OIL PRESSURE CHECK
WARNING:
q Be careful not to burn yourself, as engine oil is hot.
q Engine oil pressure check should be done in "Parking position".
1. Check engine oil level. Refer to LU-6, "ENGINE OIL LEVEL" .
2. Remove engine undercover with power tool.
3. Disconnect oil pressure switch harness connector.
4. Remove oil pressure switch using the deep socket (commercial
