Elise/Exige is factory filled with a 50% concentration of Havo-

line XLC Extended Life Coolant, which contains Organic Acid

Technology (OAT) based corrosion inhibitors to provide efficient

cooling performance combined with long coolant change inter-

vals and freedom from environmentally damaging phosphates,

silicates and nitrites.

NOTICE: No other type of coolant should be mixed with this

OAT coolant.

Havoline XLC may be identified by its orange colouration,

and by a label around the header tank filler neck. The 50% con

centration provides freezing protection down to -40°F (-40°C),

and is recommended to be maintained throughout the life of the

car. Stronger concentrations should not be used.

In an emergency, if an OAT coolant is not available, the

cooling system should be topped up using water only, but the

reduction in freezing protection should be recognised, and the

concentration corrected promptly. In areas where the tap water

is extremely hard (exceeding 250 parts per million), distilled,

de-ionised or filtered rain water should be used for the water

content of the coolant mix.

The effective level of ethylene glycol (anti-freeze) in the sys

tem may be measured by your dealer using a hydrometer, but in

order to ensure that the required level of corrosion protection is

maintained, the coolant should be renewed every 4 years.

For coolant capacity, refer to 'Recommended Lubricants'

and 'Technical Data'.

NOTICE: Using an incorrect coolant mixture may result in expen

sive damage to the engine and/or other vehicle parts caused by

overheating, freezing or corrosion effects. This damage would

not be covered by the new car warranty.
