 PRECAUTIONS

PRECAUTIONS PFP:00001

Precautions for Liquid Gasket EBS00T6X

LIQUID GASKET APPLICATION PROCEDURE

1. Remove old liquid gasket adhering to the liquid gasket application surface and the mating surface.
● Remove liquid gasket completely from the liquid gasket application surface, 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 Tool.
Use Genuine Silicone RTV Sealant or equivalent. Refer to
GI-46, "RECOMMENDED CHEMICAL PRODUCTS AND SEAL-
ANTS" .
Tool number :WS39930000 ( — )
● Within 5 minutes of liquid gasket application, install the mating
component.
● If liquid gasket protrudes, wipe it off immediately.
● Do not retighten bolts or nuts after the installation.
● Wait 30 minutes or more after installation before refilling PBIC2160E

engine oil and engine coolant.

Inspection EBS00T71

ENGINE OIL LEVEL

NOTE: LU
Before starting engine, park vehicle on a level surface 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.
C
2. Insert oil level gauge and make sure the engine oil level is within
the range (A) as shown.
3. If it is out of range, adjust it.

ENGINE OIL APPEARANCE

● Check engine oil for white turbidity or heavy contamination. G
● If engine oil becomes turbid and white, it is highly probable that it is contaminated with engine coolant.
Repair or replace damaged parts.
H
ENGINE OIL LEAKAGE
Check for engine oil leakage around the following areas:
● Oil pan (upper and lower) I
● Oil pan drain plug
● Oil pressure switch
● Oil filter J
● Intake valve timing control solenoid valve
● Front cover
● Mating surface between cylinder block and cylinder head K
● Mating surface between cylinder head and rocker cover
● Crankshaft oil seals (front and rear)
L
● Oil filter (for intake valve timing control)
OIL PRESSURE CHECK
WARNING: M
● Be careful not to burn yourself, as engine oil may be hot.
● For engine oil pressure check the transaxle should be in “ Park position” (A/T models) and (CVT
models) or “Neutral position” (M/T models), and apply the parking brake securely.
1. Disconnect harness connector at oil pressure switch (1), and
remove oil pressure switch using a suitable tool.
● Oil pan (lower) (2)

2. Install oil pressure gauge and hose.

Tool number : ST25051001 (J-25695-1)
: ST25052000 (J-25695-2)

WBIA0571E

3. Check engine oil level. Refer to LU-5, "ENGINE OIL LEVEL" .

4. Start engine and warm it up to normal operating temperature.
5. 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)]
Engine speed Approximate discharge pressure
rpm kPa (bar, kg/cm2 , psi)
Idle speed More than 60 (0.60, 0.61, 9)
2,000 More than 200 (2.0, 2.0, 29)

If difference is extreme, check oil passage and oil pump for oil leaks.
6. 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 specification.
Use Genuine Silicone RTV Sealant or equivalent. Refer to GI-46, "RECOMMENDED CHEMICAL
PRODUCTS AND SEALANTS" .
Oil pressure switch : 14.7 N·m (1.5 kg-m, 11 ft-lb)
c. Check engine oil level. Refer to LU-5, "ENGINE OIL LEVEL" .
d. After warming up engine, make sure there are no engine leaks of oil with running engine.
Changing Engine Oil EBS00T72

WARNING:
● Be careful not to burn yourself, as engine oil may be 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, park vehicle on a level surface and check for engine oil leakage from engine compo-
nents. Refer to LU-5, "ENGINE OIL LEAKAGE" .
2. Stop engine and wait for 10 minutes.

5. Install drain plug (2) with new washer. Refer to EM-24, "Compo-
nents" .
CAUTION:
Be sure to clean drain plug (2) and install with new washer. C
6. Refill with new engine oil.
Refer to MA-11, "RECOMMENDED FLUIDS AND LUBRI-
CANTS" . D
CAUTION:
● The refill capacity depends on the engine oil temperature
and drain time. Use these specifications for reference E
only.
● Always use oil level gauge to determine the proper
amount of engine oil in the engine. F
7. Warm up engine and check area around drain plug (2) and oil fil-
ter (3) for engine oil leakage.
8. Stop engine and wait for 10 minutes. G
9. Check the engine oil level. Refer to LU-5, "ENGINE OIL LEVEL" PBIC3915E
