Engine Cooling System: Removal & Installation Mitsubishi Outlander II рестайлинг

>> A << THERMOSTAT INSTALLATION

Install the thermostat with care to avoid peeling or damage to the rubber ring. When installing the thermostat, face the jiggle valve of the thermostat upward.

Scheme 8

Install the thermostat so that the jiggle valve is facing straight up. Be careful not to fold or scratch the rubber ring.

Scheme 9

>> B << HOSE CLIP/RADIATOR LOWER HOSE INSTALLATION

1. Make mating mark on a new hose clip in the same position as the remove one.
2. Insert the radiator hose until the protrusion of the water inlet fitting.
3. Align the mating marks on the radiator hose and hose clamp, and then connect the radiator hose.
4. Remove the hose clip claw to tighten the radiator hose.

Scheme 10

Scheme 11

1. Immerse the thermostat in water, and heat the water while stirring. Check the thermostat valve opening temperature. Standard value: Valve opening temperature: 87 ± 1.5°C (189 ± 3°F) < 2.4L ENGINE > 82 ± 1.5°C (180 ± 3°F) < 3.0L ENGINE >
2. Check that the amount of valve lift is at the standard value when the water is at the full-opening temperature. NOTE: Measure the valve height when the thermostat is fully closed, and use this measurement to compare the valve height when the thermostat is fully open. Standard value: Full-opening temperature: 95°C (203°F) Amount of valve lift: 8.5 mm (0.335 inch) or more < 2.4L ENGINE > 9.0 mm (0.354 inch) or more < 3.0L ENGINE >

Scheme 18

1. Apply the specified sealant to the thread of the engine coolant temperature sensor. Specified Sealant: ThreeBond 1324N or equivalent NOTE: Install the engine coolant temperature sensor immediately after applying sealant. CAUTION: After the installation, until a sufficient period of time (one hour or more) elapses, do not apply the oil or water to the sealant application area or start the engine.
2. Use special tool MB992042 to tighten the engine coolant temperature sensor to the specified torque. Tightening torque: 30 ± 9 N.m (22 ± 7 ft-lb)

Use special tool MB992042 to remove the engine coolant temperature sensor.

Scheme 19

<< C >> THERMOSTAT HOUSING REMOVAL

Remove the two control wiring harness clamps, and remove the thermostat housing.

Scheme 20

Insert the O-ring to the water inlet pipe, and coat the outer portion of the O-ring with water or engine coolant.

Scheme 21

>> B << GASKET/THERMOSTAT HOUSING INSTALLATION

Using the special tool MD998412, install the thermostat housing while supporting the gasket.

Scheme 22

Scheme 23

1. Apply the specified sealant to the thread of the engine coolant temperature sensor. Specified Sealant: ThreeBond 1324N or equivalent NOTE: Install the engine coolant temperature sensor immediately after applying sealant. CAUTION: After the installation, until a sufficient period of time (one hour or more) elapses, do not apply the oil or water to the sealant application area or start the engine.
2. Use special tool MB992042 to tighten the engine coolant temperature sensor to the specified torque. Tightening torque: 30 ± 9 N.m (22 ± 7 ft-lb)

>> D << HOSE CLIP/RADIATOR UPPER HOSE INSTALLATION

1. Make mating mark on a new hose clip in the same position as the remove one.
2. Insert the radiator hose until the protrusion of the thermostat housing.
3. Align the mating marks on the radiator hose and hose clamp, and then connect the radiator hose.
4. Remove the hose clip claw to tighten the radiator hose.

>> A << RADIATOR HOSE/HOSE CLIP INSTALLATION

Scheme 24

1. Make mating mark on a new hose clip in the same position as the remove one.
2. Insert the radiator hose until the protrusion of the pipe.
3. Align the mating marks on the radiator hose and hose clip.
4. Remove the hose clip claw and shorten the hose clip, then install the radiator hose.

Scheme 25

<< A >> HOSE CLIP/RADIATOR HOSE REMOVAL

1. Make mating marks on the radiator hose and the hose clip as shown to install them in the original position.
2. Break off the tip of hose clip claw and spread out the hose clip, then disconnect the radiator hose. NOTE: If there is a hose clip claw, the hose clip cannot spread to capacity because the claw contacts the hose clip.

1. Make mating mark on a new hose clip in the same position as the remove one.
2. Insert the radiator hose until the protrusion of the pipe.
3. Align the mating marks on the radiator hose and hose clip.
4. Remove the hose clip claw and shorten the hose clip, then install the radiator hose.
