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 pintle will not
damage the IAC valve. The purpose of the 28 mm set-
ting 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.
