Coolant specification

The quality of the coolant which is used can have a
great effect on the efficiency and life of the cooling
system. The recommendations indicated below can
help to maintain a good cooling system and to protect
it against frost and/or corrosion.
If the correct procedures are not used, Wimborne
Marine Power Centre cannot be held responsible for
damage caused by frost or corrosion, or for loss of
cooling efficiency.
The correct coolant/anti-freeze to use is Extended
Life Coolant.
Extended Life Coolant
Qty: 5 litres Part No 60061
Qty: 25 litres Part No 60062
The coolant mixture must be a 50/50 mix with clean
water.
'Extended Life Coolant' has a service life of 6000
service hours or 3 years which ever is sooner.
'Extended Life Coolant' should not be mixed with
other products.
Unlike many protective coolants, 'Extended Life
Coolant' does not coat components with a protective
layer to prevent corrosion. Instead it uses virtually
non-depleting corrosion inhibitors.
An alternative to 'Extend Life Coolant' is Havoline
(XLC) Extended Life Coolant/Anti-freeze.
Caution: Using a coolant/anti-freeze which coats
components with a protective layer to prevent
corrosion may impair the efficiency of the cooling
system and lead to the engine overheating.
An anti-freeze which contains the correct inhibitor
must be used at all times to prevent damage to the
engine by corrosion, because of the use of aluminium
in the coolant circuit.
If frost protection is not necessary, it is still extremely
important to use an approved anti-freeze mixture
because this gives a protection against corrosion and
also raises the boiling point of the coolant.
Note: If combustion gases are released into the
coolant circuit, the coolant must be renewed.
