Coolant
The coolant is a mixture of water, antifreeze
and corrosion inhibitor. It performs the
following functions in the cooling system:
•
Antifreeze protection
•
Increased efficiency of the cooling
system
•
Offers anti-corrosion protection
NOTE: Use Mobil Extra Antifreeze in all
climates, all year round. If coolant is
not used, the cooling system will not
be sufficiently protected from
corrosion and the cooling system
efficiency will be reduced.
NOTE: To prevent damage to the
engine, only top up with a pre-mixed
coolant that provides the desired level
of antifreeze protection.
If antifreeze/corrosion inhibitor is present in
the correct concentration, the boiling point
of the coolant will be around 130°C (266°F).
The antifreeze and corrosion inhibitor
concentration in the cooling system should
be approximately 50% ±5%. This will
protect the cooling system against freezing
in temperatures of -40°C (-40°F).
The antifreeze and corrosion inhibitor
concentration in the cooling system should
not exceed 55%, which provides antifreeze
protection down to -45°C (-49°F), as a
higher concentration will not dissipate heat
as effectively.
If the vehicle is losing coolant, do not drive
your vehicle and contact your McLaren
retailer.
