| warning |
When removing the radiator cap, use care to avoid contact
with hot engine coolant or steam. Place a shop towel over the radiator cap and turn the radiator
cap anti-clockwise a little to let the pressure escape through the vinyl tube. After relieving
the steam pressure, remove the radiator cap by slowly turning it anti-clockwise.
|
Drain the engine coolant from the radiator, heater core and engine after unplugging the
radiator drain plug and removing the radiator cap.
|
|
2.Drain the engine coolant in the water jacket by unplugging the drain plug of the cylinder
block.
3.Remove the radiator condenser tank and drain the engine coolant.
4.Drain the engine coolant then clean the path of the engine coolant by injecting water
into the radiator from the radiator cap area.

5.Apply the designated sealant to the screw area of the cylinder block drain plug, and then
tighten to the standard torque.
Specified sealant: 3M Nut Locking Part No.4171
or equivalent
Tightening torque: 40 ± 5 N·m
6.Securely tighten the drain plug of the radiator.
7.Reinstall the radiator condenser tank.

8.
| caution |
Do not use alcohol or methanol anti-freeze or any engine coolant mixed
with alcohol or methanol anti-freeze. The use of an improper anti-freeze can cause corrosion
of the aluminium components.
|
By referring to the section on engine coolant, select an appropriate concentration for
safe operating temperature within the range of 45 to 60%. Use special tool LLC changer (MB991871)
to refill the engine coolant. A convenient mixture is a 50% water and 50% antifreeze
solution (freezing point: -31°C).
Recommended antifreeze: High-quality ethylene
glycol based coolant
Quantity: 6.0 L
| note |
For how to use special tool MB991871, refer to its manufacturer’s instructions.
|
9.Reinstall the radiator cap.
10.Start the engine and let it warm up until the thermostat opens.
11.After repeatedly revving the engine up to 3,000 r/min several times, then
stop the engine.
12.Remove the radiator cap after the engine has become cold, and pour in engine coolant
up to the brim. Reinstall the radiator cap.
13.
| caution |
Do not overfill the radiator condenser tank.
