REMOVAL AND INSTALLATION <2.4L ENGINE>
Pre-removal Operation
Post-installation Operation
Removal steps
Required Special Tool:
REMOVAL SERVICE POINTS
HOSE CLIP/RADIATOR UPPER HOSE DISCONNECTION
1. Make mating marks on the radiator hose and the hose clamp as shown to install them in the original position. Then, remove them.
2. Break off the tip of hose clip claw and spread out the hose clip.
NOTE: If there is a hose clip claw, the hose clip cannot spread to capacity because the claw contacts the hose clip.
3. Disconnect the radiator lower hose.
ENGINE COOLANT TEMPERATURE SENSOR REMOVAL
Use special tool MB992042 to remove the engine coolant temperature sensor.
INSTALLATION SERVICE POINTS
O-RING INSTALLATION
CAUTION
Avoid 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.
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
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)
HOSE CLIP/RADIATOR UPPER HOSE CONNECTION
CAUTION
Never reuse the hose clip whose claw is broken off to prevent the rusting.
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 outlet fitting.
3. Align the mating marks on the radiator hose and hose clamp, and then connect the radiator hose.
