5. Make up a solution of anti-freeze and water in
a separate container in the concentration
required. To allow for topping -up, and for
filling the expansion tank, prepare a quantity in
excess of the cooling system capacity.
6. Remove t he radiator filler cap and fill the
radiator until the coolant level is just below the
filler neck and refit the cap.
Engine protection
To prevent corrosion of aluminium engine parts it is
vital that the cooling system is filled with a solution
of clean water and anti-freeze winter and summer.
Never fill or top-up with water only. always add
anti-freeze. Never use salt water otherwise corrosion
will occur. In certain territories where the only
available water supply may have some salt content,
use only clean rain water o r distilled water, with
anti- freeze added.
7. Fill the expansion tank to approximately half
full and refit the cap.

Anti-freeze should be used even in climates where it
is not necessary.
below t he filler neck. Top -
up the expansion
tank to about half full. Fit both filler caps.
Anti-freeze can remain in the cooling system and
will provide adequate protection for two years
provided that the specific gravity of the coolant is
checked before the onset of the second winter and
topped-up with new anti - freeze as required.
Land Rovers leaving the factory have the cooling
system filled with a 50% anti- freeze mixture. This
gives protection down t o minus 47 degrees
Centigrade (minus 53 degrees Fahrenheit).
After the second winter t he system should be
drained and thoroughly flushed. Before adding new
anti-freeze examine all joints and renew defective
hoses t o make sure that the system is leak proof.
