7. CAUTION: Radiator internal pressure must not exceed 100 kPa (14.5 psi). Failure to follow this instruction may cause damage to the radiator.
Flush the radiator using the hose pipe until the coolant flowing from the radiator lower coolant hose connection is clear.
8. Remove the hose pipe from the radiator upper coolant hose connection.
9. Connect a hose pipe to the upper coolant hose using a suitable connector.
10. Flush the engine using the hose pipe until the coolant flowing from the radiator lower coolant hose is clear.
11. Remove the hose pipe from the upper coolant hose connection.
12. Connect the upper coolant hose to the radiator.
13. Install the thermostat. For additional information, refer to thermostats.
14. Fill the cooling system. For additional information, refer to Cooling System Draining, Filling and Bleeding.
15. Install the undertray.
16. Install the air cleaner. For additional information, refer to Powertrain Management.
Cooling System Backflushing
CAUTION: The heater core must be backflushed separately from the engine cooling system to prevent the engine cooling system particles from
clogging the heater core tubes and reducing (or eliminating) coolant flow through the heater core.
All engine cooling system flushing and backflushing procedures must include a separate backflushing of the heater core after the flushing or
backflushing of the engine cooling system.
CAUTION: Heater core internal pressure must not exceed 100 kPa (14.5 psi). Failure to follow this instruction may cause damage to the heater
core.
NOTE: Cooling system backflushing should be carried out before the cooling system components are installed after the cooling system flushing
procedure.
1. Disconnect the heater outlet coolant hose from the engine and connect the heater hose to a suitable hose pipe.
2. Disconnect the heater inlet coolant hose from the engine and allow the coolant to drain into a suitable container.
3. Turn the water supply valve to the hose ON and allow water pressure to flow through the heater core.
4. Allow water pressure to flow through the heater core for approximately five minutes.
5. Turn the water supply valve to the hose OFF and disconnect the hose pipe from the heater hose.
6. Connect the heater inlet coolant hose to the engine.
7. Connect the heater outlet coolant hose to the engine.
8. Fill the cooling system as described using a 50% mixture of Jaguar Premium Cooling System Fluid or equivalent meeting Jaguar specification
ESE-M97B44-A and 50% distilled water.
9. Test the system for correct heater performance with the specified engine cooling system conditions.
Radiator Backflushing
1. Remove the radiator. For additional information, refer to Radiator.
2. Invert the radiator.
3. Connect a suitable hose pipe to the lower coolant hose connection of the radiator.
4. Turn the water supply valve to the hose ON and allow water pressure to flow through the radiator.
5. Allow water pressure to flow through the radiator for approximately five minutes.
6. Turn the water supply valve to the hose OFF and disconnect the hose pipe from the radiator.
7. Allow the coolant to drain from the radiator.
8. Install the radiator. For additional information, refer to Radiator.
Engine Backflushing
NOTE: Make sure that the thermostat is removed before backflushing the engine.
1. Position the high-pressure water hose into the engine through the engine return and backflush the engine.
2. Connect a suitable hose pipe to the upper coolant hose connection of the engine.
3. Turn the water supply valve to the hose ON and allow water pressure to flow through the engine.
4. Allow water pressure to flow through the engine for approximately five minutes.
5. Turn the water supply valve to the hose OFF and disconnect the hose pipe from the upper coolant hose connection of the engine.
6. Connect the upper coolant hose to the engine.
7. Fill the cooling system as described using a 50% mixture of Jaguar Premium Cooling System Fluid or equivalent, meeting Jaguar
specification ESE-M97B44-A and 50% distilled water.
