NOTE:
To remove rust, sludge and other foreign material from the cooling system, use Premium
Cooling System flush, meeting Jaguar specification EGR-M14P7-A, which is safe for use
with aluminium cooling systems. This cleaning restores cooling system efficiency and
helps prevent overheating.
NOTE:
In severe cases where cleaning solvents will not properly clean the cooling system, it will
be necessary to use the pressure flushing method using Cooling System Flusher, 164-
R3670 to restore efficient operation.
NOTE:
A pulsating or reversed direction of flushing water will loosen sediment more quickly
than a steady flow in the normal coolant flow direction.
