• After disassembling, or exposing any internal engine parts, change engine oil and replace oil filter with a new
one.
• Release air within route when refilling after draining engine coolant.
• After repairing, start the engine and increase engine speed to check engine coolant, fuel, engine oil, and
exhaust gases for leakage.
Liquid Gasket
INFOID:0000000010624149
REMOVAL OF LIQUID GASKET SEALING
• After removing mounting nuts and bolts, separate the mating sur-
face using the seal cutter [SST: KV10111100] (A) and remove old
liquid gasket sealing.
CAUTION:
Never damage the mating surfaces.
• Tap the seal cutter [SST: KV10111100] to insert it
, and then
slide it
by tapping on the side as shown in the figure.
• In areas where the seal cutter [SST: KV10111100] is difficult to use,
lightly tap the parts using a plastic hammer to remove it.
CAUTION:
If for some unavoidable reason tool such as a screwdriver is
used, be careful not to damage the mating surfaces.
LIQUID GASKET APPLICATION PROCEDURE
1.
Using a scraper (A), remove old liquid gasket adhering to the liq-
uid gasket application surface and the mating surface.
• Remove 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 liquid gasket tube to the tube presser (commercial ser-
vice tool).
Use Genuine Liquid Gasket or equivalent.
4.
Apply liquid gasket without gaps to the specified location accord-
ing to the specified dimensions.
• If there is a groove for liquid gasket application, apply liquid
gasket to the groove.
• As for bolt holes
, normally apply liquid gasket inside the
holes. Occasionally, it should be applied outside the holes.
Check to read the text of this manual.
• Within five minutes of liquid gasket application, install the mat-
ing component.
• If liquid gasket protrudes, wipe it off immediately.
• Do not retighten mounting bolts or nuts after the installation.

Inspection
INFOID:0000000010624154
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 check that the engine oil level is within
the range
shown in the figure.
3.
If it is out of range, adjust it.
ENGINE OIL APPEARANCE
• Check engine oil for white turbidity or heavy contamination.
• If 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.
• Oil pan (upper and lower)
• Oil pan drain plug
• Oil pressure sensor
• Oil filter
• Oil cooler
• Intake valve timing control solenoid valve
• Exhaust valve timing control solenoid valve
• Front cover
• VTC cover
• Mating surface between cylinder block and cylinder head
• Mating surface between cylinder head and camshaft bracket
• Mating surface between camshaft bracket and rocker cover
• Mating surface between camshaft bracket and high pressure fuel pump
• Crankshaft oil seals (front and rear)
OIL PRESSURE CHECK
WARNING:
• Be careful not to get burned, as engine oil may be hot.
• When checking engine oil pressure, shift position should be “Parking position”, and apply parking
brake securely.
1.
Check engine oil level.

Precaution for Liquid Gasket
INFOID:0000000010284204
REMOVAL OF LIQUID GASKET
• After removing the mounting bolts and nuts, separate the mating
surface using a seal cutter and remove the liquid gasket.
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 gasket applied area.
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.
• Remove the liquid gasket completely from the groove of the
gasket 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.
• If there is a groove for the liquid gasket application, apply the
gasket to the groove.
• As for the bolt holes, normally apply the 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 gasket application, install the mating
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 coolant.
CAUTION:
If there are instructions in this manual, observe them.

Precautions for Removing Battery Terminal
INFOID:0000000010508724
• With the adoption of Auto ACC function, ACC power is automatically supplied by operating the intelligent key
or remote keyless entry or by opening/closing the driver side door. In addition, ACC power is supplied even
after the ignition switch is turned to the OFF position, i.e. ACC power is supplied for a certain fixed time.
• When disconnecting the 12V battery terminal, turn off the ACC
power before disconnecting the 12V battery terminal, observing
“How to disconnect 12V battery terminal” described below.
NOTE:
Some ECUs operate for a certain fixed time even after ignition
switch is turned OFF and ignition power supply is stopped. If the
battery terminal is disconnected before ECU stops, accidental DTC
detection or ECU data damage may occur.
• For vehicles with the 2-batteries, be sure to connect the main bat-
tery and the sub battery before turning ON the ignition switch.
NOTE:
If the ignition switch is turned ON with any one of the terminals of
main battery and sub battery disconnected, then DTC may be detected.
• After installing the 12V battery, always check "Self Diagnosis Result" of all ECUs and erase DTC.
NOTE:
The removal of 12V battery may cause a DTC detection error.
HOW TO DISCONNECT 12V BATTERY TERMINAL
Disconnect 12V battery terminal according to Instruction 1 or Instruction 2 described below.
For vehicles parked by ignition switch OFF, refer to Instruction 2.
INSTRUCTION 1
1.
Open the hood.
2.
Turn key switch to the OFF position with the driver side door opened.
3.
Get out of the vehicle and close the driver side door.
4.
Wait at least 3 minutes. For vehicle with the engine listed below, remove the battery terminal after a lapse
of the specified time.
CAUTION:
While waiting, never operate the vehicle such as locking, opening, and closing doors. Violation of
this caution results in the activation of ACC power supply according to the Auto ACC function.
5.
Remove 12V battery terminal.
CAUTION:
After installing 12V battery, always check self-diagnosis results of all ECUs and erase DTC.
INSTRUCTION 2 (FOR VEHICLES PARKED BY IGNITION SWITCH OFF)
1.
Unlock the door with intelligent key or remote keyless entry.
NOTE:
At this moment, ACC power is supplied.
2.
Open the driver side door.
3.
Open the hood.
4.
Close the driver side door.
5.
Wait at least 3 minutes.
CAUTION:
While waiting, never operate the vehicle such as locking, opening, and closing doors. Violation of
this caution results in the activation of ACC power supply according to the Auto ACC function.
6.
Remove 12V battery terminal.
