Removal and Installation
Removal
• W ARNINGS:
Avoid flames, sparks or lighted substances.
W ait for a minimum of 1 minute after the engine has stopped before carrying out any repair to the fuel injection
system.
• CAUTIONS:
Make sure that the area around the component is clean and free of foreign material.
Make sure that all openings are sealed. Use new blanking caps.
Fuel injectors must not be dismantled or the nozzles cleaned, not even with ultrasonic equipment. Install new fuel
injectors if necessary.
Fuel injectors must be installed to their original position.
Cap the fuel injector nozzle to prevent damage before storing vertically.
Fuel injectors must be stored vertically and immediately capped when removed, to prevent the fuel from draining.
If a new component has been installed, configure using Land Rover approved diagnostic equipment.
Bleed the fuel system by cranking the engine to purge the air from the system.
• NOTE: If the fuel injectors are to be removed or replaced as a set, installation should be done in pairs. Injectors 2 and
3, 1 and 4 respectively.
Disconnect the battery ground cable.
Refer to:
Specifications
(414-00 Battery and Charging System -
General Information, Specifications).
