REMOVAL SERVICE POINTS
 
 
<<A>> HOSE CLIP/RADIATOR UPPER HOSE DISCONNECTION
1. Make mating marks on the radiator upper 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 upper hose.
noteIf there is a hose clip claw, the hose clip cannot spread to capacity because the claw contacts the hose clip.
 

 
 
<<B>> ENGINE COOLANT TEMPERATURE SENSOR REMOVAL
Use special tool MB992042 to remove the engine coolant temperature sensor.
 
 
 
 
INSTALLATION SERVICE POINTS
 
 
>>A<< O-RING INSTALLATION
cautionAvoid adhesion of engine oil or grease to the O-ring.
Fit the O-ring in the water inlet 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 specified sealant to the thread of the engine coolant temperature sensor.
Specified sealant: ThreeBond 1324N or equivalent
noteInstall the engine coolant temperature sensor immediately after applying sealant.
2.
cautionAfter 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.
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)
 

 
 
>>C<< RADIATOR UPPER HOSE/HOSE CLIP CONNECTION
1.
cautionNever reuse the hose clip whose claw is broken off to prevent the rusting.
Make mating mark on a new hose clip in the same position as the remove one.
2. Insert the radiator upper hose until the protrusion of the water outlet fitting.
3. Align the mating marks on the radiator upper hose and hose clip.
4. Remove the hose clip claw and shorten the hose clip, then install the radiator upper hose.
