REMOVAL SERVICE POINTS

<<A>> RADIATOR UPPER HOSE DISCONNECTION

Make mating marks on the radiator hose and hose clamp as shown to install them in the original position. Then, remove them.

<<B>> ENGINE COOLANT TEMPERATURE SENSOR REMOVAL

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

INSTALLATION SERVICE POINTS

>>A<< O-RING INSTALLATION
caution Do not allow engine oil or other grease to adhere to the O-ring

Fit the O-ring in the water pipe groove, wet the O-ring circumference or the pipe mounting area inner wall, and then insert the O-ring.

>>B<< ENGINE COOLANT TEMPERATURE SENSOR INSTALLATION

1.Apply the sealant to the thread of engine coolant temperature sensor.
Specified sealant: ThreeBond 1324N or equivalent
note Install the engine coolant temperature sensor immediately after applying sealant.

2.
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.
In the same manner as for removal, using special tool water temperature sensor wrench (MB992042), tighten to the specified torque.
Tightening torque: 30 ± 9 N·m

>>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.
