The lubrication method is a fully force-fed, full-flow
filtration type. The engine oil pump is a trochoid type
which is driven by the crankshaft <4G1>.The engine
oil pump is a gear type which is driven by the
crankshaft via the balancer timing belt <4G6>.
ENGINE OILS
Health Warning
Prolonged and repeated contact with mineral oil will
result in the removal of natural fats from the skin,
leading to dryness, irritation and dermatitis. In
addition, used engine oil contains potentially harmful
contaminants which may cause skin cancer.
Adequate means of skin protection and washing
facilities must be provided.
Recommended Precautions
The most effective precaution is to adapt working
practices which prevent, as far as practicable, the
risk of skin contact with mineral oils, for example by
using enclosed systems for handling used engine oil
and by degreasing components, where practicable,
before handling them. Other precautions:
•Avoid prolonged and repeated contact with oils,
particularly used engine oils.
•Wear protective clothing, including impervious
gloves where practicable.•Avoid contaminating clothes, particularly
underpants, with oil.
•Do not put oily rags in pockets, the use of overalls
without pockets will avoid this.
•Do not wear heavily soiled clothing and
oil-impregnated foot-wear. Overalls must be
cleaned regularly and kept separate from
personal clothing.
•Where there is a risk of eye contact, eye
protection should be worn, for example, chemical
goggles or face shields; in addition an eye wash
facility should be provided.
•Obtain first aid treatment immediately for open
cuts and wounds.
•Wash regularly with soap and water to ensure all
oil is removed, especially before meals (skin
cleansers and nail brushes will help). After
cleaning, the application of preparations
containing lanolin to replace the natural skin oils
is advised.
•Do not use petrol, kerosine, diesel fuel, gas oil,
thinners or solvents for cleaning skin.
•Use barrier creams, applying them before each
work period, to help the removal of oil from the
skin after work.
•If skin disorders develop, obtain medical advice
without delay.

GENERAL INFORMATION
ENGINE COOLING14-2
GENERAL INFORMATION
M1141000100371The cooling system is designed to keep every part of
the engine at appropriate temperature in whatever
condition the engine may be operated. The cooling
method is of the water-cooled, pressure forced
circulation type in which the water pump pressurizes
coolant and circulates it throughout the engine. If the
coolant temperature exceeds the prescribed temperature, the thermostat opens to circulate the
coolant through the radiator as well so that the heat
absorbed by the coolant may be radiated into the air.
The water pump is of the centrifugal type and is
driven by the alternator drive belt from the
crankshaft. The radiator is the corrugated fin, down
flow type.

ENGINE COOLANT LEAK CHECKM1141001000300
WARNING
When pressure testing the cooling system,
slowly release cooling system pressure to
avoid getting burned by hot coolant.
CAUTION
•Be sure to completely clean away any
moisture from the places checked.
•When the tester is taken out, be careful not to
spill any coolant.
•Be careful when installing and removing the
tester and when testing not to deform the
filler neck of the radiator.
1. Check that the coolant level is up to the filler neck.
Install a radiator tester and apply 160 kPa
pressure, and then check for leakage from the
radiator hose or connections.
2. If there is leakage, repair or replace the
appropriate part.
RADIATOR CAP VALVE OPENING
PRESSURE CHECK
M1141001300389
NOTE: Be sure that the cap is clean before
testing. Rust or other foreign material on the cap
seal will cause an improper reading.
1. Use a cap adapter to attach the cap to the tester.2. Increase the pressure until the indicator of the
gauge stops moving.
Minimum limit: 83 kPa
Standard value: 93 − 123 kPa
3. Replace the radiator cap if the reading does not
remain at or above the limit.
ENGINE COOLANT REPLACEMENTM1141001200434
WARNING
When removing the radiator cap, use care to
avoid contact with hot coolant or steam.
Place a shop towel over the cap and turn the
cap counterclockwise a little to let the
pressure escape through the vinyl tube.
After relieving the steam pressure, remove
the cap by slowly turning it
counterclockwise.
1. Drain the water from the radiator, heater core and
engine after unplugging the radiator drain plug
and removing the radiator cap.
2. Drain the water in the water jacket by unplugging
the drain plug of the cylinder block.
3. Remove the radiator condenser tank and drain
the coolant.
4. Drain the coolant then clean the path of the
coolant by injecting water into the radiator from
the radiator cap area.

Tightening torque:
40 ± 5 N⋅m <4G1>

6. Securely tighten the drain plug of the radiator.
7. Reinstall the radiator condenser tank.
CAUTION
Do not use alcohol or methanol anti-freeze or any
engine coolants mixed with alcohol or methanol
anti-freeze. The use of an improper anti-freeze
can cause corrosion of the aluminium
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 LLC changer (MB991871) to refill the
coolant. A convenient mixture is a 50% water and
50% antifreeze solution (freezing point: −31°C).
Recommended antifreeze: DIAQUEEN SUPER
LONG LIFE COOLANT or equivalent
Quantity:
5.0 L <4G1>
7.0 L <4G6>
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 coolant up to the brim.
Reinstall the cap.
CAUTION
Do not overfill the radiator condenser tank.
13.Add coolant to the radiator condenser tank
between the "F" and "L" mark if necessary.
CONCENTRATION MEASUREMENTM1141001100352
Measure the temperature and specific gravity of the
engine coolant to check the antifreeze concentration.
Standard value: 30 − 60% (allowable
concentration range)
Recommended antifreeze: DIAQUEEN SUPER
LONG LIFE COOLANT or equivalent
CAUTION
If the concentration of the anti-freeze is below
30%, the anti-corrosion property will be
adversely affected. In addition, if the
concentration is above 60%, both the
anti-freezing and engine cooling properties will
decrease, affecting the engine adversely. For
these reasons, be sure to maintain the
concentration level within the specified range.
