Precautions for Removing Battery Terminal
INFOID:0000000012958963
When disconnecting the battery terminal, pay attention to the following.
• Always use a 12V battery as power source.
• Never disconnect battery terminal while engine is running.
• When removing the 12V battery terminal, turn OFF the ignition
switch and wait at least 30 seconds.
• For vehicles with the engine listed below, remove the battery termi-
nal after a lapse of the specified time:
NOTE:
ECU may be active for several tens of seconds after the ignition switch is turned OFF. If the battery terminal
is removed before ECU stops, then a DTC detection error or ECU data corruption may occur.
• After high-load driving, if the vehicle is equipped with the V9X engine, turn the ignition switch OFF and wait
for at least 15 minutes to remove the battery terminal.
NOTE:
• Turbocharger cooling pump may operate in a few minutes after the ignition switch is turned OFF.
• Example of high-load driving
- Driving for 30 minutes or more at 140 km/h (86 MPH) or more.
- Driving for 30 minutes or more on a steep slope.
• For vehicles with the 2-batteries, be sure to connect the main battery 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 discon-
nected, 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.
Precautions For Engine Service
INFOID:0000000012197486
DISCONNECTING FUEL PIPING
• Before starting work, check no fire or spark producing items are in the work area.
• Release fuel pressure before disconnecting and disassembly.
• After disconnecting pipes, plug openings to stop fuel leakage.
DRAINING ENGINE COOLANT
Drain engine coolant and engine oil when the engine is cooled.
INSPECTION, REPAIR AND REPLACEMENT
Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.
REMOVAL AND DISASSEMBLY
• When instructed to use SST, use specified tools. Always be careful to work safely, avoid forceful or unin-
structed operations.
• Exercise maximum care to avoid damage to mating or sliding surfaces.

• Dowel pins are used for several parts alignment. When replacing and reassembling parts with dowel pins,
check that dowel pins are installed in the original position.
• Must cover openings of engine system with a tape or equivalent, to seal out foreign materials.
• Mark and arrange disassembly parts in an organized way for easy troubleshooting and reassembly.
• When loosening nuts and bolts, as a basic rule, start with the one furthest outside, then the one diagonally
opposite, and so on. If the order of loosening is specified, do exactly as specified. Power tools may be used
in the step.
ASSEMBLY AND INSTALLATION
• Use torque wrench to tighten bolts or nuts to specification.
• When tightening nuts and bolts, as a basic rule, equally tighten in several different steps starting with the
ones in center, then ones on inside and outside diagonally in this order. If the order of tightening is specified,
do exactly as specified.
• Replace with new gasket, packing, oil seal or O-ring.
• Thoroughly wash, clean, and air-blow each part. Carefully check engine oil or engine coolant passages for
any restriction and blockage.
• Avoid damaging sliding or mating surfaces. Completely remove foreign materials such as cloth lint or dust.
Before assembly, oil sliding surfaces well.
• 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. Check for leakages of engine coolant, fuel,
engine oil, and exhaust gases.
Liquid Gasket
INFOID:0000000012197487
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.

PRECAUTIONS
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.
• After 30 minutes or more have passed from the installation, fill
engine oil and engine coolant.
CAUTION:
If there are specific instructions in this manual, observe them.

COMPONENT PARTS
Oil Pump
INFOID:0000000012197489
• A variable capacity electronic control oil pump is used for minimiz-
ing oil pump drive loss.
• The variable engine oil pressure control solenoid valve switches
between high and low engine oil pressure. This stops the spray of
oil from the piston oil jet when the pressure is low, reducing oil
pump drive resistance and reducing the stirring resistance from
rotating parts caused by the oil. The objective is to improve fuel
economy.
For control, refer to
EC-635, "ENGINE OIL PRESSURE CONTROL
Oil Cooler
INFOID:0000000012197490
• For minimizing oil pump drive loss, an oil cooler that reduces pres-
sure loss by approximately 30% compared to the previous oil
cooler is adopted.
• For maintaining a stable oil temperature, an oil cooler is adopted
for the coolant system.
• It is installed directly to the oil pan (upper).
