Notice: Before removal, the fuel rail assembly may
be cleaned with a spray-type cleaner, following
package instructions. Do not immerse the fuel rails
in liquid cleaning solvent. Use care in removing
the fuel rail assembly to prevent damage to the
electrical connectors and injector spray tips.
Prevent dirt and other contaminants from entering
open lines and passages. Fittings should be
capped and holes plugged during service.
Important: If an injector becomes separated from
the rail and remains in the cylinder head, replace
the injector O-ring seals and the retaining clip.

OXYGEN SENSOR
Removal and Installation Procedure
1. Disconnect the negative battery cable.
Notice: The oxygen sensor uses a permanently
attached pigtail and connector. This pigtail should
not be removed from the oxygen sensor. Damage
or removal of the pigtail or the connector could
affect proper operation of the oxygen sensor. Do
not drop the oxygen sensor.
2. Disconnect the electrical connector.
3. Carefully remove the oxygen sensor from the
exhaust pipe.
Installation Notice
Tightening Torque
6 N•m (53 lb-in)
Tightening Torque
55 N•m (41 lb-ft)
4. Remove the pedal and sensor assembly.
5. Installation should follow the removal procedure
in the reverse order.
Important: A special anti-seize compound is used
on the oxygen sensor threads. This compound
consists of aliquid graphiteand glass beads. The
graphite will burn away, but the glass beads will
remain, making the sensor easier to remove. New
or serviced sensors will already have the
compound applied to the threads. If a sensor is
removed from any engine and is to be reinstalled,
the threads must havean antiseize compound
applied before reinstallation.
4. Coat the threads of the oxygen sensor with an anti-
seize compound, if needed.
5. Installation should follow the removal procedure
in the reverse order.
