Precautions For Liquid GasketEBS00ODQ
REMOVAL OF LIQUID GASKET
●After removing the mounting bolts and nuts, separate the mating
surface using a seal cutter and remove the old liquid gasket
sealing.
CAUTION:
Be careful not to damage the mating surfaces.
●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-blade
screwdriver is used, be careful not to damage the mating
surfaces.
LIQUID GASKET APPLICATION PROCEDURE
1. Using a scraper, remove the old liquid gasket adhering to the liq-
uid gasket application surface and the mating surface.
●Remove the liquid gasket completely from the groove of the
liquid gasket application surface, mounting bolts and bolt
holes.
2. Wipe the liquid gasket application surface and the mating sur-
face with white gasoline (lighting and heating use) to remove
adhering moisture, grease and foreign materials.
3. Attach the liquid gasket to the tube presser.
Use Genuine Liquid Gasket or equivalent.
4. Apply the liquid gasket without breaks to the specified location
with the specified dimensions.
●If there is a groove for the liquid gasket application, apply the
liquid gasket to the groove.
●As for the bolt holes, normally apply the liquid gasket inside
the holes. If specified, it should be applied outside the holes.
Make sure to read the instruction in this manual.
●Within five minutes of liquid gasket application, install the mat-
ing component.
●If the liquid gasket protrudes, wipe it off immediately.
●Do not retighten after the installation.
●After 30 minutes or more have passed from the installation, fill
the engine oil and engine coolant.
CAUTION:
If there are instructions in this manual, observe them.

InspectionEBS00KO3
ENGINE OIL LEVEL
●Before starting the engine, put vehicle horizontally then check
the engine oil level. If the engine is already started, stop it and
allow 10 minutes before checking.
●Check that the engine oil level is within the range shown in the
figure.
●If it is out of range, adjust it.
ENGINE OIL APPEARANCE
●Check the engine oil for white turbidity or remarkable contamination.
●If the engine oil becomes turbid and white, it is highly probable that it is contaminated with engine coolant.
Find the cause and repair.
ENGINE OIL LEAKAGE
Check for engine oil leakage around the following area.
●Oil pan
●Oil pan drain plug
●Oil pressure switch
●Oil filter
●Oil cooler
●Intake valve timing control cover and intake valve timing control solenoid valve
●Front cover
●Mating surface between cylinder block and cylinder head
●Mating surface between cylinder head and rocker cover
●Crankshaft oil seal.
OIL PRESSURE CHECK
WARNING:
●Be careful not to burn yourself, as the engine oil is hot.
●Engine oil pressure check should be done in “ Parking
position” (A/T model) or “Neutral position” (M/T model).
1. Check engine oil level. Refer to LU-7, "
ENGINE OIL LEVEL" .
2. Remove the undercover.
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.
Engine oil pressure [Engine oil temperature at 80 °C (176 °F)]
5. After checking, install the oil pressure switch as follows.
a. Remove old sealant adhering to the switch and engine.
b. Apply thread sealant.
Use Genuine Liquid Gasket or equivalent.

Changing Engine OilEBS00KO4
WARNING:
●Be careful not to burn yourself, as the engine oil is 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.
1. Warm up engine, put vehicle horizontally and check for engine
oil leakage from engine components.
2. Stop engine and wait for 10 minutes.
3. Remove drain plug and oil filler cap.
4. Drain engine oil.
●Install drain plug and refill with new engine oil.
Engine oil specifications and viscosity:
●API grade SG, SH, SJ or SL.
●ILSAC grade GF-I, GF-II or GF-III
●ACEA 96-A2
●Refer to MA-16, "RECOMMENDED FLUIDS AND LUBRICANTS" for further detail.
Engine oil capacity (Approximate):
Unit: (lmp qt)
CAUTION:
●Be sure to clean drain plug and install with new washer.
●The refill capacity depends on the engine oil temperature and drain time. Use these specifica-
tions for reference only.
●Always use the dipstick to the determine when the proper amount of engine oil is in the engine.
5. Warm up engine and check area around drain plug and oil filter for engine oil leakage.
6. Stop engine and wait for 10 minutes.
7. Check engine oil level. Refer to LU-7, "
ENGINE OIL LEVEL" . Oil pressure switch:
: 12.3 - 17.2 N·m (1.25 - 1.75 kg-m, 9 - 12 ft-lb)
