To add coolant
The 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.
Except for vehicles with turbocharger
If the level should drop below the “LOW” level on the reserve
tank, open the lid and add coolant to “FULL” level.
Also, if the reserve tank is completely empty, remove the radia-
tor cap (A) and add coolant until the level reaches the filler
neck.
Vehicles with turbocharger
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-freeze
The 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 High-quality ethylene glycol based coolant. It has excel-
lent protection against corrosion and rust formation of all met-
als including aluminium and can avoid blockages 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
required concentration of anti-freeze differs depending on the
expected ambient temperature.
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.
