when engine temperature is below 48°C (120°F). Excessive
force may damage threads in the exhaust manifold.
- Carefully remove the HO2S1 from the exhaust manifold.


Installation Procedure
Important : A special anti-seize compound is used on
the oxygen sensor threads. This compound consists of
a liquid graphite and glass beads. The graphite will burn
away, but the glass beads will remain, making the sensor
easier to remove. New or service sensors will already
have the compound applied to the threads. If a
sensor is removed from any engine and if for any reason
it is to be reinstalled, the threads must have anti-seize
compound applied before reinstallation.

seat and the air passage with a suitable fuel system
cleaner. Do not use methyl ethyl ketone.


Installation Procedure
Important : If installing a new IAC valve, be sure to replace
it with an identical part. The IAC valve pintle shape
and diameter are designed for the specific application.
Measure the distance between the tip of the IAC valve
pintle and the mounting flange. If the distance is greater
than 28 mm, use finger pressure to slowly retract the
pintle.
The force required to retract the pintle will not
damage the IAC valve.The purpose of the 28 mm setting
is to prevent the IAC pintle from bottoming out on
the pintle seat. This 28 mm setting is also an adequate
setting for controlled idle on a restart.
