Maintenance

Engine coolant

To check the coolant level
A translucent coolant reserve tank is located in the
engine compartment.
Petrol-powered vehicles
Check the coolant level in the reserve tank. The re-
serve tank lid (B) is equipped with a dipstick.
Remove the dipstick and wipe it with a clean cloth.
Reinsert the dipstick as far as it goes. Remove the
dipstick and read the coolant level, which should al-
ways be within the range "F" (FULL) or "L"
(LOW) while the engine is cold.
To add coolant
The cooling system is a closed system and normal-
ly the loss of coolant should be very slight. A no-
8
ticeable drop in the coolant level could indicate leak-
age. If this occurs, we recommend you to have the
system checked as soon as possible.
If the level should drop below the "L" (LOW) level
on the dipstick, add coolant to the reserve tank.
8-06
Also, if the reserve tank is completely empty, re-
move the radiator cap (A) and add coolant until the
E01000501361
level reaches the filler neck.
WARNING
l Do not open the radiator cap while the en-
gine is hot. The coolant system is under
pressure and any hot coolant escaping
could cause severe burns.
Anti-freeze
The engine coolant contains an ethylene glycol anti-
corrosion agent. The cylinder head and water pump
housing are cast aluminium alloy, and periodic
changing of the engine coolant is necessary to pre-
vent corrosion of these parts.
Use "DIA QUEEN SUPER LONG LIFE COOL-
ANT" or equivalent.
MITSUBISHI Genuine Coolant has excellent pro-
FULL
tection against corrosion and rust formation of all
metals including aluminium and can avoid block-
LOW
ages in the radiator, heater, cylinder head, engine
block, etc.
Because of the necessity of this anti-corrosion
agent, the coolant must not be replaced with plain
water even in summer. The required concentration
of anti-freeze differs depending on the expected am-
bient temperature.

CAUTION
l
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 cor-
rosion of the aluminium components.
l For effective anti-corrosion and anti-
freeze performance, keep the anti-freeze
concentration within the range of 30 to
60 %.
Concentrations exceeding 60 % will re-
sult in a reduction of both the anti-freeze
and cooling performance thus adversely
affecting the engine.
l Do not top up with water only.
Water by itself reduces the rust-protec-
tive and anti-freeze qualities of the cool-
ant and has a lower boiling point. It can
also cause damage to the cooling system if
it should freeze. Do not use tapwater, as it
can cause corrosion and rust formation.
