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.

Wave Pattern Observation Points
Check that the standard wave pattern appears when the stepper motor is operating.
Point A: Presence or absence of induced electromotive force from the motor turning. (Refer to the abnormal
wave pattern.)
Contrast with standard wave patternProbable cause
Induced electromotive force does not appear or is extremely small.Motor is malfunctioning
Point B: Height of coil reverse electromotive force
Contrast with standard wave patternProbable cause
Coil reverse electromotive force does not appear or is extremely small.Short in the coil
Examples of Abnormal Wave Pattern
DExample 1
Cause of problem
Motor is malfunctioning. (Motor is not operating.)
Wave pattern characteristics
Induced electromotive force from the motor turning does
not appear.
DExample 2
Cause of problem
Open circuit in the line between the stepper motor and
the engine-ECU.
Wave pattern characteristics
Current is not supplied to the motor coil on the open
circuit side. (Voltage does not drop to 0 V.)
Furthermore, the induced electromotive force waveform
at the normal side is slightly different from the normal
waveform.

ENGINE COOLING -GeneralInformation/
Service Specifications/Lubricant/Sealant14-2
GENERAL INFORMATION
The cooling system is designed to keep every part
of the engine at appropriate temperature in
whatever condition the engine may be operated.
The cooling method is of the water-cooled, pressure
forced circulation type in which the water pump
pressurizes coolant and circulates it throughout the
engine. If the coolant temperature exceeds the
prescribed temperature, the thermostat opens to
circulate the coolant through the radiator as well
so that the heat absorbed by the coolant may be
radiated into the air.The water pump is of the centrifugal type and is
driven by the drive belt from the crankshaft.
The radiator is the corrugated fin, down flow type.
The cooling fan is controlled by the radiator fan
controller and engine-ECU depend on driving
conditions.

INSTALLATION SERVICE POINTS
"AATHERMOSTAT INSTALLATION
Install the thermostat being careful not to fold over or scratch
the rubber ring.
Caution
Make absolutely sure that no oil is adhering to the rubber
ring of the thermostat. In addition, be careful not to fold
over or scratch the rubber ring when inserting. If the
rubber ring is damage, replace the thermostat.
"BARADIATOR UPPER HOSE CONNECTION
1. Insert each hose as far as the projection of the water
outlet fitting.
2. Align the mating marks on the radiator hose and hose
clamp, and then connect the radiator hose.
INSPECTION
THERMOSTAT CHECK
1. Immerse the thermostat in water, and heat the water while
stirring. Check the thermostat valve opening temperature.
Standard value:
Valve opening temperature: 80±1.5_C
2. Check that the amount of valve lift is at the standard value
when the water is at the full-opening temperature.
Standard value:
Full-opening temperature: 93_C
Amount of valve lift: 9.5 mm or more
NOTE
Measure the valve height when the thermostat is fully
closed, and use this measurement to calculate the valve
height when the thermostat is fully open.
