Trouble Diagnoses
EKS003CF
Aiming AdjustmentEKS003CG
When performing headlamp aiming adjustment, use an aiming machine, aiming wall screen or headlamp
tester. Aimers should be in good repair, calibrated and operated in accordance with respective operation man-
uals.
If any aimer is not available, aiming adjustment can be done as follows:
For details, refer to the regulations in your own country.
lKeep all tires inflated to correct pressures.
lPlace vehicle and tester on one and same flat surface.
lSee that there is no-load in vehicle (coolant, engine oil filled up to correct level and full fuel tank) other
than the driver (or equivalent weight placed in driver's position).

Precautions For Liquid GasketEBS009SQ
REMOVAL OF LIQUID GASKET SEALING
lAfter removing the mounting bolts and nuts, disconnect and
remove the liquid gasket sealing using a seal cutter.
CAUTION:
Be careful not to damage the mating surfaces.
lIn 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.
LIQUID GASKET APPLICATION PROCEDURE
1. Using a scraper, remove the old liquid gasket adhering to the
gasket application surface and the mating surface.
lRemove the liquid gasket completely from the groove of the gas-
ket application surface, mounting bolts, and bolt holes.
2. Wipe the gasket application surface and the mating surface 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 gasket without breaks to the specified location with the
specified dimensions.
lIf there is a groove for the liquid gasket application, apply the
gasket to the groove.
lAs 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 service manual.
lWithin five minutes of gasket application, install the mating com-
ponent.
lIf the liquid gasket protrudes, wipe it off immediately.
lDo not retighten after the installation.
lAfter 30 minutes or more have passed from the installation, fill
the engine oil and coolant.
CAUTION:
If there are specific instructions in the service manual, observe
them.

OIL LEVEL AND MUDDINESS
lBefore starting the engine, check the oil level. If the engine is
already started, stop it and allow 10 minutes before checking.
lCheck that the oil level is within the range shown in the figure.
lIf it is out of range, adjust it.
lCheck the oil for white turbidity or remarkable contamination.
lIf the oil becomes turbid and white, it is highly probable that it is
contaminated with coolant. Find the cause and repair.
OIL LEAKAGE
Check for oil leakage around the following area.
lOil pan
lOil pan drain plug
lOil pressure switch
lOil filter
lIntake valve timing control cover
lFront cover
lMating surface between cylinder block and cylinder head
lMating surface between cylinder head and rocker cover
lCrankshaft oil seal.
OIL PRESSURE CHECK
WA RN ING:
lBe careful not to burn yourself, as the engine oil is hot.
lOil pressure check should be done in “ Parking position”.
1. Check the oil level.
2. Remove the under cover.
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 [Oil temperature is 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.

1. Warm up engine, and check for oil leakage from engine compo-
nents.
2. Stop engine and wait for 10 minutes.
3. Remove drain plug and oil filler cap.
4. Drain oil and refill with new engine oil.
Oil specification and viscosity:
lAPI grade SG, SH or SJ.
lILSAC grade GF-I or GF-II
lRefer toMA-17, "RECOMMENDED FLUIDS AND LUBRICANTS".
Oil capacity (Approximate):
CAUTION:
lBe sure to clean drain plug and install with new washer.
lThe refill capacity depends on the oil temperature and drain time. Use these specifications for ref-
erence only.
Always use the dipstick to the determine when the proper amount of oil is in the engine.
5. Warm up engine and check area around drain plug and oil filter for oil leakage.
6. Stop engine and wait for 10 minutes.
7. Check oil level.
