REMOVAL SERVICE POINT
AA"DRIVE BELT REMOVAL
Due to the adoption of the Serpentine drive system with the
auto-tensioner, the following operation is required:
1. Insert the 12.7sq. spinner handle and etc. into the tool
hole of the auto-tensioner and rotate it counterclockwise
until the auto-tensioner gets to the stopper.
2. Align hole A with hole B for fixing by inserting the L-shaped
hexagon wrench, then remove the drive belt.
Caution
When the drive belt is reused, use a chalk to indicate
an arrow of rotation direction on the back of the belt
so that it can be re-assembled in the same direction
as before.

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.

Replace the O-ring for the water inlet pipe with a new part,
and apply water on the periphery of the O-ring so that it
can be inserted easily into the water pump and thermostat
housing.
Caution
(1) Never apply grease or oil, such as engine oil, on the
O-ring.
(2) Install the water inlet pipe onto the thermostat
housing, and then fix.
