3. Use special tool to tighten bolts according to the following
procedure (tightening for plastic zone)
(1) According to the sequence specified in the figure,
tighten the bolt to the specified torque 78±2 N·m.
(2) In the reverse sequence of the figure, fully loosen
bolts.
(3) According to the sequence specified in the figure,
tighten bolts to the specified torque 20±2 N·m.
(4) Indicate paint markings on the heads of cylinder head
bolts and cylinder head, and tighten bolts at the angle
of 90 degree in the sequence specified in the figure.
(5) When bolts are tightened at the angle of 90 degree
according to the figure, ensure that the paint markings
on the heads of cylinder head bolts and cylinder head
are standing in line.
Caution
1) When the tightening angle is under 90 degree,
the bolt is not sufficiently tightened.
2) When the tightening angle exceeds the
specified value, remove the bolt and repeat
the same procedure beginning with Step 1.

FORM-IN-PLACE-GASKET
FIPG is used for several members of this engine. With this gasket, caution is required to the application
amount, application procedure and state of the application surface so that the performance is sufficiently
attained.
If sufficient gasket is not applied, leaks could occur, and if too much is applied, the gasket could protrude
and plug or restrict the oil and water flow passage. Thus, to prevent leaks from the joined sections,
it is absolutely necessary to evenly apply the correct amount.
The FIPG used for the engine parts reacts with moisture in the air and hardens so use it for the normal
metal flange parts.
DISASSEMBLY
The parts assembled with FIPG can be easily disassembled without special means. However, in some
cases, the sealant on the seams must be broken by lightly tapping with a wood hammer or similar tool.
A smooth and thin gasket scraper can be lightly tapped into the seams but in this case, take care not
to damage the seams.
The special tool oil pan remover (MD998727) is set for this purpose.
WASHING THE GASKET SURFACE
Completely remove all matters adhered on the gasket surfaces with a gasket scraper or wire brush.
Confirm that the FIPG application surface is smooth. There must be no grease or foreign matter on
the gasket surface.
Always remove the old FIPG that has entered the mounting holes and screw holes.
APPLICATION PROCEDURES
Apply an even coat of FIPG within the predetermined radius. Completely cover the areas around the
mounting holes. The FIPG can be wiped off if it has not hardened. Install at the set position while the
FIPG is still wet (within 15 minutes). When installing, maker sure that the FIPG does not get on areas
other than the required areas. After installing, do not subject the application areas to oil or water or
start the engine until the FIPG has sufficiently hardened (approx. one hour). The FIPG application procedures
differ according to the member, so follow the procedures given in this manual and apply the FIPG.
