PRECAUTIONS

PRECAUTIONS PFP:00001

Precautions for Liquid Gasket ABS000P2

REMOVAL OF LIQUID GASKET SEALING
q After removing the mounting bolts and nuts, separate the mating
surface using a seal cutter and remove the liquid gasket sealing.
CAUTION:
Be careful not to damage the mating surfaces.
q In areas where the cutter is difficult to use, use a plastic hammer
to lightly tap the areas where the liquid gasket is applied.
CAUTION:
If for some unavoidable reason a tool such as a flat-bladed
screwdriver is used, be careful not to damage the mating sur-
faces.
PBIC0002E

LIQUID GASKET APPLICATION PROCEDURE
1. Using a scraper, remove the old liquid gasket adhering to the
gasket application surface and the mating surface.
q Remove the liquid gasket completely from the groove of the liq-
uid gasket application surface, mounting bolts, and bolt holes.
2. Wipe the gasket application surface and the mating surface
removing any adhering moisture, grease and foreign material.
3. Attach the liquid gasket tube to the tube presser.
Use Genuine RTV Silicone Sealant or equivalent. Refer to
GI-46, "RECOMMENDED CHEMICAL PRODUCTS AND SEAL-
ANTS".
PBIC0003E

4. Apply the liquid gasket without breaks to the specified location
with the specified dimensions.
q If there is a groove for the liquid gasket application, apply the liq-
uid gasket to the groove.

EMA0622D

q As for the bolt holes, normally apply the gasket inside the holes.
Occasionally, it should be applied outside the holes. Make sure
to read the text of this manual.
q Within five minutes of liquid gasket application, install the mating
component.
q If the liquid gasket protrudes, wipe it off immediately.
q Do not retighten after the installation.
q Wait 30 minutes or more after installation before refilling the
engine with oil and coolant.
CAUTION: SEM159F
If there are specific instructions in this manual, observe them.

Inspection ABS000MB

ENGINE OIL LEVEL
NOTE:
Before starting the engine, check the engine oil level. If the engine is already started, stop it and allow 15 min-
utes 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

OIL APPEARANCE
q Check the engine oil for a white milky appearance or excessive contamination.
q If the engine oil is milky, it is highly probable that it is contaminated with engine coolant. Repair the broken
parts.
OIL LEAKAGE
Check for 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 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 the engine oil is hot.
q Oil pressure check should be done in "Parking position".
1. Check the engine oil level. Refer to LU-6, "Inspection" .
2. Remove the engine under cover with power tool.
3. Remove the oil pressure switch to connect the oil pressure
gauge.
4. After warming up the engine, check that oil pressure corre-
sponding to the engine speed is produced.
NOTE:
When engine oil temperature is low, the engine oil pressure
becomes high.
