To check the coolant levelA translucent coolant reserve tank is located in the engine com-
partment.Petrol-powered vehiclesCheck the coolant level in the reserve tank. The reserve 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 always be within the range “F”
(FULL) or “L” (LOW) while the engine is cold.
To add coolantThe cooling system is a closed system and normally the loss of
coolant should be very slight. A noticeable drop in the coolant
level could indicate leakage. 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 dip-
stick, add coolant to the reserve tank.
Also, if the reserve tank is completely empty, remove the radia-
tor cap (A) and add coolant until the level reaches the filler
neck.Anti-freezeThe engine coolant contains an ethylene glycol anti-corrosion
agent. The cylinder head and water pump housing are cast alu-
minium alloy, and periodic changing of the engine coolant is
necessary to prevent corrosion of these parts.
Use “DIA QUEEN SUPER LONG LIFE COOLANT” or
equivalent.
MITSUBISHI Genuine Coolant has excellent protection
against corrosion and rust formation of all metals including
aluminium and can avoid blockages in the radiator, heater, cyl-
inder head, engine block, etc.

WARNING
!●Do not open the radiator cap while the engine is hot.
The coolant system is under pressure and any hot
coolant escaping could cause severe burns.

To add coolantThe cooling system is a closed system and normally the loss of
coolant should be very slight. A noticeable drop in the coolant
level could indicate leakage. If this occurs, we recommend you
to have the system checked as soon as possible.
If the level should drop below the “LOW” level on the reserve
tank, open the lid and add coolant.Anti-freezeThe engine coolant contains an ethylene glycol anti-corrosion
agent. The cylinder head and water pump housing are cast alu-
minium alloy, and periodic changing of the engine coolant is
necessary to prevent corrosion of these parts.
Use only “BASF Glysantin Alu Protect Premium/G30”.
It has excellent protection against corrosion and rust formation
of all metals including aluminium and can avoid clogs in the
radiator, heater, cylinder head, engine block, etc.
Because of the necessity of this anti-corrosion agent, the cool-
ant must not be replaced with plain water even in summer.
The anti-freeze must fill 50 % concentration coolant in all tem-
perature conditions.
During cold weatherIf the temperatures in your area drop below freezing, there is
the danger that the coolant in the engine or radiator could
freeze and cause severe damage to the engine and/or radiator.
Add a sufficient amount of anti-freeze to the coolant to prevent
it from freezing.
The engine coolant mixture used at the factory provides protec-
tion against freezing for temperatures as low as approximately–30 °C. The concentration should be checked before the start of
cold weather and anti-freeze added to the system if necessary.
WARNING
!●Do not open the reserve tank cap while the engine is
hot. The coolant system is under pressure and any
hot coolant escaping could cause severe burns.
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.●Do not top up with water only.
Water by itself reduces the rust-protective and anti-
freeze qualities of the coolant and has a lower boil-
ing 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.
