1. Remove the air cleaner. Refer to «Intake Air Distribution and Filtering»(ref-312577) article.
2. Remove the air cleaner. Refer to «Intake Air Distribution and Filtering»(ref-312594) article.
3. Remove the thermostat. Refer to «Thermostat - Removal and Installation (Vehicles With: Supercharger)»(ref-312545-S37224791872009041400000) or «Thermostat - Removal and Installation (Vehicles Without: Supercharger)»(ref-312545-S09078879672009041400000) .
4. Detach the lower coolant hose from the radiator and position to one side.
5. Detach the upper coolant hose from the radiator. 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 aluminum 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. NOTE: Dispose of old coolant and flushing water contaminated with coolant and cleaning chemicals in accordance with local, state and federal laws.
