REMOVAL SERVICE POINT

<<A>> OIL PRESSURE SWITCH REMOVAL

Measure the dimension "A" shown in the illustration, and select the appropriate special tool Oil pressure switch socket wrench (MD998054 or MD998012)in the table shown below. Remove the engine oil pressure switch.

Dimension "A"	Special tool No.
26 mm	MD998054
27 mm	MD998012

INSTALLATION SERVICE POINTS

>>A<< WATER OUTLET FITTING INSTALLATION

1.Apply a 3 mm diameter bead of FIPG to the indicated surface of the water outlet fitting.
Specified sealant:
Mitsubishi Genuine Part No.MD970389 or equivalent
2.Install the housing quickly (within 15 minutes) while the sealant is wet and tighten the bolts to the specified torque.
Tightening torque: 13 ± 2 N·m

note

After installation, keep the sealed area away from the coolant for approximately one hour.

>>B<< SEALANT APPLICATION TO ENGINE COOLANT TEMPERATURE SENSOR

caution

When using a tool, avoid letting it touch the connector portion which is made of plastic.

1.Remove all old sealant remaining on the threads of the coolant temperature sensor and in the threaded hole in the thermostat housing.
2.Apply sealant to the coolant temperature sensor’s threads indicated in the drawing.
Specified sealant:
LOCTITE 262 or equivalent

>>C<< SEALANT APPLICATION TO OIL PRESSURE SWITCH

1.Apply sealant to the threaded portion.
Specified Sealant:
3M ATD Part No.8660 or equivalent

2.Measure the dimension "A" shown in the illustration, and select the appropriate special tool Oil pressure switch socket wrench (MD998054 or MD998012) in the table shown below. Tight the engine oil pressure switch to the specified toque.
Tightening torque: 19 ± 3 N·m

Dimension "A"	Special tool No.
26 mm	MD998054
27 mm	MD998012

>>D<< THERMOSTAT HOUSING INSTALLATION

1.Remove all old FIPG remaining on the thermostat housing and cylinder head.
2.Apply a 3 mm diameter bead of FIPG on the indicated surface of the thermostat housing.
Specified sealant:
Mitsubishi Genuine Part No.MD970389 or equivalent

3.Coat the bolt with sealant, then install and tighten it.
Specified sealant:
3M ATD Part No.8672 or equivalent

Tightening torque: 24 ± 4 N·m

note

After installation, keep the sealed area away from the coolant for approximately one hour.

>>E<< THERMOSTAT INSTALLATION

1.Check that the rubber ring is undamaged and seated correctly in the thermostat flange.
2.Install the thermostat as shown in the illustration. The jiggle valve must be at the uppermost position.

>>F<< INLET MANIFOLD STAY INSTALLATION

1.Install the inlet manifold stay and tighten the bolts just finger tight.
2.Check to ensure that the stay is in close contact with the bosses of the inlet manifold and cylinder block.
3.First tighten the inlet manifold side bolts to the specified torque, then the cylinder block side bolts to the specified torque.
Tightening torque: 31 ± 3 N·m

>>G<< WATER INLET PIPE/O-RING INSTALLATION

caution

Keep the O-ring free of oil or grease.

1.Attach a new O-ring to each end of the water inlet pipe.
2.Wet the O-ring with water.
3.Insert the rear end of the pipe into the thermostat housing.
