3.5.2.4 Injector Installation
Follow these guidelines to prevent damage to the injector and its electrical interface during
the replacement or re-installation process.
●
Lubrication: Apply a light coating of lubricant to the lower injector seal ring. ISO 10 light
mineral oil or equivalent is recommended.
●
The preferred technique is to apply the lubricant to the sockets the injectors are being
installed into, rather than directly to the seal ring itself. This will help minimize the possibility of
injector contamination.
●
Avoid applying lubricant over the director plate holes
– this may restrict injector flow. Do not
dip the injector tip in lubricant.
●
The injectors come from the factory with the seal rings attached. The re-use of seal rings is
not preferred when replacing an injector. If an injector is to be re-used, and no new seal rings are
available, take care to inspect each seal ring for signs of damage. Even minor defects in the seal
ring can lead to leakage. Take extra care in installing seal ring over flange of injector inlet.
●
Carefully installing the harness connector will prevent terminal damage. Listen for a positive
audible click from the connector retention device
— this ensures that it is fully engaged.
●
Avoid unnecessarily disconnecting/reconnecting the harness connector.
●
Wires routed in a manner that can allow them to become pinched between components can
result in a short circuit and a stuck open injector.
●
For injectors that require orientation for spray pattern, do not rotate the injector in the fuel rail
assembly to install the injector electrical connector. This may dislodge the retaining clip, and
result in improper spray orientation.
The table is a list of lubricant oils that were tested and approved for O-ring lubrication. These
lubricants have shown to have no effect on injector performance (plugging, sticking).
