Glow Plug
• The glow plug is used to heat the air in the cylinder.
• The glow plug utilizes a system of sending voltage
through a resistance coil to create heat.
NOTE: The 6.4L glow plug is very similar to the glow
plug used on the 6.0L Power Stroke
®
Diesel, but they are
different. The glow plugs must not be interchanged!
NOTE: The 6.4L glow plug uses a green isolator.
Fuel Injector
• The fuel injector is controlled by an extremely
precise piezo electric actuator that can accomplish
multiple injections per combustion event.
NOTE: Never unplug a fuel injector while the engine
is running, serious engine damage could occur!
