| REMOVAL SERVICE POINT
| <<A>> OIL PRESSURE SWITCH REMOVAL
| Using special tool Oil pressure switch wrench (MD998054), removal the oil pressure switch.
| INSTALLATION SERVICE POINTS
| >>A<< WATER OUTLET FITTING INSTALLATION
| 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 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. Remove all old sealant remaining on the threads of the coolant temperature sensor and in the threaded hole in the thermostat housing. Apply sealant to the coolant temperature sensor's threads indicated in the drawing. Specified sealant: 3M ATD Part No.8660 or equivalent
| >>C<< SEALANT APPLICATION TO OIL PRESSURE SWITCH
| Apply sealant to the threaded portion. Specified Sealant: 3M ATD Part No.8660 or equivalent
| Using special tool Oil pressure switch wrench (MD998054), tighten the oil pressure switch to the specified torque. Tightening torque: 19 ± 3 N·m
| >>D<< THERMOSTAT HOUSING INSTALLATION
| Remove all old FIPG remaining on the thermostat housing and cylinder head. 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
| Coat the bolt with sealant, then install and tighten it. Specified sealant: Mitsubishi Genuine Part No.MD970389 or equivalent Install the housing quickly (within 15 minutes) while the sealant is wet and tighten the bolts to the specified torque. Tightening torque: 24 ± 4 N·m NOTE: After installation, keep the sealed area away from the coolant for approximately one hour.
| >>E<< THERMOSTAT INSTALLATION
| Check that the rubber ring is undamaged and seated correctly in the thermostat flange. Install the thermostat as shown in the illustration. The jiggle valve must be at the uppermost position.
| >>F<< SEALANT APPLICATION TO ENGINE COOLANT TEMPERATURE GAUGE UNIT
| Remove all old sealant remaining on the threaded hole in the coolant temperature gauge unit and the thermostat housing. NOTE: A new coolant temperature gauge unit is coated with sealant. It does not require coating with sealant before installation. Apply sealant to the indicated threads of the coolant temperature gauge unit. Specified sealant: 3M Nut Locking Part No.4171 or equivalent
| >>G<< INTAKE MANIFOLD STAY INSTALLATION
| Install the intake manifold stay and tighten the bolts just finger tight. Check to ensure that the stay is in close contact with the bosses of the intake manifold and cylinder block. First tighten the intake manifold side bolts to the specified torque, then the cylinder block side bolts to the specified torque. Tightening torque: 31 ± 3 N·m
| >>H<< WATER INLET PIPE/O-RING INSTALLATION CAUTION Keep the O-ring free of oil or grease.
| Attach a new O-ring to each end of the water inlet pipe. Wet the O-ring with water. Insert the rear end of the pipe into the thermostat housing.
