coolants mixed with alcohol or methanol anti-freeze. The
use of an improper anti-freeze can cause the corrosion of
the aluminum components.
8. By referring to the section on coolant, select an appropriate

concentration for safe operating temperature within the
range of 30 to 60%. Use special tool MB991871 to refill the
coolant. A convenient mixture is a 50% water and 50%
antifreeze solution [freezing point:

−31°C (−32.8 °F)].

Recommended antifreeze:

Recommended antifreeze: Long Life Antifreeze

Coolant or an equivalent

Quantity:

Without rear heater 9.0 cm

(9.5 quarts)

With rear heater 10.0 cm

3

(10.6 quarts)

NOTE: For the usage of special tool MB991871, refer to the
instructions enclosed with the special tool.

9. Pour in coolant until it overflows from the air bleed bolt hole,

and then tighten the air bleed bolt.

Tightening torque: 12

− 15N⋅m (106 − 133 in-lb)

10.Reinstall the radiator cap.
11.Start the engine and let it warm up until the thermostat

opens.

12.After repeatedly revving the engine up to 3,000 r/min

several times, then stop the engine.

13.Remove the radiator cap after the engine has become cold,

and pour in coolant up to the brim. Rein stall the cap.

INSPECTION

M1141002200095

Cooling Fan Check

• Check the blades for damage and cracks.

• Check for cracks and damage around bolt holes in the fan

hub.

• If any portion of the fan is damaged or cracked, replace the

cooling fan.

Fan Clutch Check

• Check to ensure that fluid in the fan clutch is not leaking at

the case joint and seals. If fluid quantity decreases due to
leakage, the fan speed will decrease and engine overheat-
ing might result.

• When the fan attached to the engine is turned by hand, it

should have some resistance. If the fan turns lightly or
freely with no resistance, it is faulty.

• Check the bimetal strip for damage.
