IDLE AIR CONTROL VALVE
Removal Procedure
1.
Disconnect the negative battery cable.
2.
Disconnect the Idle Air Control (IAC) valve connec-
tor.
3.
Remove the IAC valve retaining bolts.
Notice : On IAC valves that have been in service, do not
push on the valve pintle. The force required to move the
pintle may damage the threads on the worm drive.
4.
Remove the IAC valve.
5.
Clean the IAC valve O–ring seal area, the pintle
valve 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 re-
place 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 pintlewill not dam-
age the IAC valve. The purpose of the 28 mmsetting 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.
1.
Lubricate a new O–ring with engine oil. Install the
new O–ring onto the valve.
2.
Install the IAC valve into the throttle body.
