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, Engines Ltd 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 6 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 t.he 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 after repair of
the fault.
