Precautions for Liquid GasketEBS01E52
LIQUID GASKET APPLICATION PROCEDURE
1. Remove the old liquid gasket adhering to the liquid gasket application surface and the mating surface.
lRemove the 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 the tube presser [SST].
Use Genuine Liquid Gasket or equivalent.
lWithin five minutes of liquid gasket application, install the mating
component.
lIf the liquid gasket protrudes, wipe it off immediately.
lDo not retighten mounting bolts and nuts after the installation.
lAfter 30 minutes or more have passed from the installation, fill
engine oil and engine coolant.

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.
1. Pull out oil level gauge and wipe it clean.
2. Insert oil level gauge and make sure the engine oil level is within
the range shown in the figure.
3. If it is out of range, adjust it.
ENGINE OIL APPEARANCE
lCheck engine oil for white turbidity or heavy contamination.
lIf 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 area.
lOil pan (lower and upper)
lOil pan drain plug
lOil pressure switch
lOil filter and oil filter bracket
lOil cooler
lOil pump housing
lVa c u u m p u m p
lCylinder head rear cover assembly
lFront and rear chain cases
lMating surface between cylinder block and cylinder head
lMating surface between cylinder head and rocker cover
lFront and rear oil seals
lTurbocharger
lOil tube connecting parts from turbocharger
ENGINE OIL PRESSURE CHECK
WARNING:
lBe careful not to burn yourself, as the engine oil may be hot.
lOil pressure check should be done in “Neutral position”(M/T models) or “Parking position”(A/T
models).
1. Check the engine oil level. Refer toLU-5, "
ENGINE OIL LEVEL".
2. Remove engine undercover front and engine undercover middle. Refer toEI-15, "
FRONT BUMPER".

3. Disconnect harness connector at oil pressure switch (1), and
remove oil pressure switch (1) using deep socket (commercial
service tool).
CAUTION:
Do not drop or shock oil pressure switch.
4. Install the oil pressure gauge and hose [SST].
5. Start engine and warm it up to normal operating temperature.
6. Check oil pressure with engine running under no-load.
NOTE:
When engine oil temperature is low, engine oil pressure becomes high.
Engine oil pressure [Engine oil temperature at 80°C(176°F)]
If difference is extreme, check oil passage and oil pump for oil leaks.
7. After the inspections, install oil pressure switch as follows.
a. Remove old liquid gasket adhering to oil pressure switch and engine.
b. Apply liquid gasket and tighten oil pressure switch to the specification.
Use Genuine Liquid Gasket or equivalent.
c. After warming up engine, make sure that there is no leakage of engine oil with running engine.
Changing Engine OilEBS01E57
WARNING:
lBe careful not to burn yourself, as the engine oil may be hot.
lProlonged 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. Refer
toLU-5, "
ENGINE OIL LEAKAGE".
2. Stop engine and wait for 10 minutes.

3. Loosen oil filler cap (1) and then remove drain plug (3).
4. Drain engine oil.
5. Install drain plug with new washer. Refer toEM-36, "
OIL PAN AND OIL STRAINER".
CAUTION:
Be sure to clean drain plug and install with new washer.
6. Refill with new engine oil.
Engine oil specification and viscosity:
Refer toMA-14, "
RECOMMENDED FLUIDS AND LUBRICANTS".
Engine oil capacity (Approximate):
Unit: (lmp qt)
CAUTION:
lWhen filling engine oil, do not pull out oil level gauge.
lThe refill capacity depends on the engine oil temperature and drain time. Use these specifica-
tions for reference only.
lAlways use the oil level gauge to determine when the proper amount of engine oil is in the
engine.
7. Warm up engine and check area around drain plug and oil filter for oil leakage.
8. Stop engine and wait for 10 minutes.
9. Check the engine oil level. Refer toLU-5, "
ENGINE OIL LEVEL".
