Precautions for Removing of Battery Terminal
INFOID:0000000010190461
• When removing the 12V battery terminal, turn OFF the ignition
switch and wait at least 30 seconds.
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.
• 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.
Liquid Gasket
INFOID:0000000009950374
REMOVAL OF LIQUID GASKET SEALING
• After removing mounting nuts and bolts, separate the mating sur-
face using the seal cutter [SST: KV10111100 (J-37228)] (A) and
remove old liquid gasket sealing.
CAUTION:
Be careful not to damage the mating surfaces.
• Tap the seal cutter [SST: KV10111100 (J-37228)] to insert it (B),
and then slide it (C) by tapping on the side as shown in the figure.
• In areas where the seal cutter [SST: KV10111100 (J-37228)] is dif-
ficult 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 RTV Silicon Sealant or equivalent. Refer to
22, "Recommended Chemical Products and Sealants"
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 (B), normally apply liquid gasket inside the
holes. Occasionally, it should be applied outside the holes.
Check to read the text of this instruction.
• 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 instruction, observe them.
Precautions For Engine Service
INFOID:0000000009950375
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.
