exchangers from both frost damage, and metal corrosion. The
Elise is factory filled with a 50% concentration of Havoline XLC
Extended Life Coolant, which contains Organic Acid Technology
(OAT) based corrosion inhibitors to provide long coolant change intervals combined with 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% concen
-
tration 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 ex
-
pensive damage to your engine and/or other car parts caused by overheating, freezing or corrosion effects. This damage would
not be covered by your new car warranty.
Coolant Drain /Refill Procedure The cooling system of the Lotus Elise has been carefully
optimised to allow the required cooling performance using the
minimum volume of coolant. This provides for high cooling sys
-
tem efficiency, with quick engine warm up and interior heating. When refilling the cooling system, it is vital to ensure that
the correct bleeding procedure is followed, and that no air pockets remain. This operation should be entrusted to your
Lotus dealer.
