INSTALLATION PROCEDURE
IMPORTANT: If installing a new IAC valve, replace with an identical part. The IAC valve pintle shape and diameter are designed for the specific
application.
1. Measure the distance between tip of IAC valve pintle and mounting flange.
If more than 28 mm, use finger pressure in order to slowly retract the pintle. The force required to retract the pintle of a new valve will not cause
damage to the valve.
2. Lubricate the IAC valve O-ring with clean engine oil.
3. Install the IAC valve assembly.
NOTE: Refer to Fastener Notice in Service Precautions.
4. Install the IAC valve attaching fasteners.
Tighten
Tighten the IAC valve attaching fasteners to 3.0 N.m (26 lb in.).
