Precautions for Removing of Battery Terminal

INFOID:0000000010235109

• 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.

Precautions For Engine Service

INFOID:0000000009750906

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.

PRECAUTIONS

LU-3

< PRECAUTION >

[MR16DDT ]

• 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:0000000009750907

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

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.

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.

Attach liquid gasket tube to the tube presser (commercial ser-
vice tool).
Use Genuine RTV silicon sealant or equivalent. Refer to

GI-

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 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:0000000009750912

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.

Pull out oil level gauge and wipe it clean.

Insert oil level gauge and check that the engine oil level is within
the range (A) shown in the figure.

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 cooler
• Oil temperature sensor
• Oil pan bolt
• Oil pan (upper and lower)
• Oil pan drain plug
• Oil pressure sensor
• Oil filter
• Valve timing control cover
• Valve timing control solenoid valve (intake and exhaust)
• Front cover
• Turbocharger
• Turbocharger oil tube (feed and return)
• Turbocharger oil hose
• Mating surface between high pressure fuel pump and camshaft bracket
• Mating surface between cylinder head and camshaft bracket
• Mating surface between cylinder block and cylinder head
• Mating surface between camshaft bracket and rocker cover
• 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” (CVT models) or “Neutral”

(M/T models), and apply parking brake securely.

Check engine oil level.

Disconnect harness connector at oil pressure sensor (1), and
remove oil pressure sensor using a deep socket (commercial
service tool).

CAUTION:

Never drop or shock oil pressure sensor.

Install oil pressure gauge [SST: ST25051001 (J-25695-1)] (A)
and hose [SST: ST25052000 (J-25695-2)] (B).

Start engine and warm it up to normal operating temperature.

Check oil pressure with engine running under no-load.
NOTE:
When engine oil temperature is low, engine oil pressure becomes high.

If difference is extreme, check oil passage and oil pump for oil leakage.

After the inspections, install oil pressure sensor as follows:

Remove old liquid gasket adhering to oil pressure sensor and engine.

Apply liquid gasket and tighten oil pressure sensor to specification.
Use Genuine RTV Silicon Sealant or equivalent.

Check engine oil level.

After warming up engine, check that there is no leakage of engine oil with running engine.

Draining

INFOID:0000000009750913

WARNING:

• Be careful not to get burned, 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.

Warm up the engine, and check for engine oil leakage from engine components. Refer to

LU-8, "Inspec-

tion"

Stop the engine and wait for 10 minutes.

Loosen oil filler cap.
