SUBJECT:
ANTI-FREEZE RECOMMENDATION
KEY POINTS:
REMINDER ON IMPORTANCE OF USING PHOSPHATE-FREE ANTI-FREEZE
All dealers are reminded of the extreme importance of using only phosphate-free anti-freeze in Jaguar cooling systems.
A special phosphate-free anti-freeze, P/N JAG 605050, is available from Jaguar Parts. This anti-freeze is recommended for all Jaguar vehicles.
A 55% concentration must be maintained at all times. Weaker solutions can cause damage to the cooling system due to the reduction of inhibitor
strength.
Some anti-freeze manufacturers claim that their product is suitable for aluminum engines. The only readily available phosphate-free anti-freeze suitable
for Jaguar cooling systems is as listed above.
For further details, please refer to TSB J83/10 and TSB J84/25.
