Liquid Gasket

INFOID:0000000007579607

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.
• After 30 minutes or more have passed from the installation, fill

engine oil and engine coolant.

ENGINE OIL

Inspection

INFOID:0000000007579612

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.
