REMOVAL SERVICE POINT
<> RADIATOR UPPER HOSE
DISCONNECTION
After making mating marks on the radiator upper
hose and hose clamp, disconnect the radiator upper
hose.
INSTALLATION SERVICE POINTS
>>A<< COOLING WATER LINE O-RING
INSTALLATION
CAUTION
Do not allow engine oil or other grease to adhere
to the cooling water line O-ring
Insert the cooling water line O-ring to the water pump
water inlet pipe, and coat the outer portion of the
cooling water line O-ring with water or engine
coolant.
>>B<< THERMOSTAT CASE
ASSEMBLY/COOLING WATER OUTLET
HOSE FITTING INSTALLATION
1. Use a gasket scraper or wire brush to completely
eliminate all gasket material on the gasket
mounting surface.
2. Apply a bead of the specified sealant.
Specified Sealant: MITSUBISHI GENUINE
PART No.MD970389 or equivalent
3. With the sealant still wet (within 15 minutes after
the sealant is applied), install the thermostat case
assembly or cooling water outlet hose fitting. Do
not apply the sealant in an area more than the
required.
>>C<< RADIATOR UPPER HOSE
CONNECTION
1. Insert radiator upper hose as far as the projection
of the cooling water outlet hose fitting.
2. Align the mating marks on the radiator upper hose
and hose clamp, and then connect the radiator
upper hose.

1. Disconnect the vacuum hose (red stripe) from
throttle body and connect it to a hand vacuum
pump.
2. Plug the nipple from which the vacuum hose was
removed.
3. When the engine is cold or hot, apply a vacuum of
53 kPa, and check the condition of the vacuum.
When engine is cold
(Engine coolant temperature: 40°C or less)
When engine is hot
(Engine coolant temperature: 80°C or higher)
PURGE PORT VACUUM CHECKM1173001500177
1. Disconnect the vacuum hose (red stripe) from the
throttle body and connect a hand vacuum pump to
the nipple.
2. Plug the vacuum hose (red stripe).3. Start the engine.
4. Check that a fairly constant negative pressure is
generated regardless of the engine speed.
5. If no negative pressure is generated, the port is
probably blocked and should be cleaned.

NOTE: When disconnecting the vacuum hose,
always make a mark so that it can be reconnected at
original position.
1. Disconnect the vacuum hose from the solenoid
valve.
2. Disconnect the harness connector.
3. Connect a hand vacuum pump to nipple (A) of the
solenoid valve (refer to the illustration at left). Engine condition Normal condition
