- Remove the fuel fired heater retaining bolt.







8. Remove the fuel fired heater.
- Disconnect the coolant hoses.







Installation
1. Install the fuel fired heater.
- Connect the coolant hoses.







2. Attach the fuel fired heater.
- Install the fuel fired heater retaining bolt.







3. Install the fuel fired heater retaining nuts.







4. Connect the fuel fired heater fuel line.







5. Connect the fuel fired heater electrical connectors.







6. Remove the hose clamping tools.







7. Install the radiator splash shield.







8. Install the fender splash shield.
9. START and RUN the engine.

CAUTION: Do not RUN the engine with the coolant expansion tank pressure cap removed. Failure to follow this instruction may cause damage to the vehicle.

10. SET the heating system to MAX heat, the blower motor to MAX speed and the air distribution to instrument panel registers.
11. Allow the engine to RUN until hot air is emitted from the instrument panel registers, while observing the engine temperature gauge.

CAUTION: Observe the engine temperature gauge. If the engine starts to over-heat switch off immediately and allow to cool. Failure to follow this instruction may cause damage to the vehicle.

12. Switch off the engine.
13. Allow the engine to cool.
14. Release the cooling system pressure.
- Remove the coolant expansion tank pressure cap.

WARNING: Never remove the coolant pressure cap under any circumstances while the engine is operating. Failure to follow this instruction may result in personal injury. To avoid having scalding hot coolant or steam blow out of the cooling system, use extreme care when removing the coolant pressure cap from a hot cooling system. Wait until the engine has cooled, then wrap a thick cloth around the coolant pressure cap and turn it slowly until the pressure begins to release. Step back while the pressure is released from the system. When certain all the pressure has been released (still with a cloth) turn and remove the coolant pressure cap from the coolant expansion tank. Failure to follow these instructions may result in personal injury.

15. Fill the cooling system up to the MAX mark on the coolant expansion tank using a fifty percent mixture of Jaguar Premium Cooling System Fluid or equivalent, meeting Jaguar specification WSS M97B44-D and fifty percent water.
16. Install the coolant expansion tank pressure cap.
