Jaguar X-Type JJM 21 02 20/15 - Manual (Page 162)

7-12 Maintenance
Engine anti-freeze
Anti-freeze, when used at the correct
concentration, not only protects the
engine from frost damage in winter, it
also provides all year round protection
against internal corrosion.
The cooling system should be filled or
replenished with a mixture of 50 per cent
water and 50 per cent anti-freeze,
conforming to specification:
WSS M97B44, coloured orange, Extended
Life Coolant.
This mixture gives frost protection for
temperatures down to -40°C.
Do not mix any other anti-freeze with
that specified; inferior quality anti-freeze
may be ineffective in maintaining
adequate frost and corrosion protection
to the cooling system.
The coolant solution may remain in the
cooling system for five years or
250,000 km after which the system
should be drained, flushed and refilled.
Engine block heater
For further information consult your
Jaguar Dealer.
Caution: The fitting of an engine
block heater does not eliminate the
need for anti-freeze under freezing
conditions.
