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 efficiency of the
cooling system 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 266°F
(130°C). 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°F
(-40°C).
The antifreeze and corrosion inhibitor
concentration in the cooling system should
not exceed 55%, which provides antifreeze
protection down to -49°F (-45°C) as a
higher concentration will not dissipate heat
as effectively.
If the vehicle is losing coolant do not drive
your vehicle. Contact your McLaren Retailer
immediately.
