1. Idle air control (IAC) valve electrical connector
2. IAC valve attaching screw
3. IAC valve assembly
On IAC valves that have been in service: Do not push or pull on the IAC valve pintle. The force required to move the pintle may damage the
threads on the worm drive. Also, Do not soak the IAC valve in any liquid cleaner or solvent, as damage may result.
CLEANING AND INSPECTION
^ Clean IAC valve O-ring sealing surface, pintle valve seat and air passage.
-
Use carburetor cleaner and a parts cleaning brush to remove carbon deposits. Do Not use a cleaner that contains methyl ethyl ketone. It is an
extremely strong solvent, and not necessary for this type of deposit.
-
Shiny spots on the pintle or seat are normal, and do not indicate misalignment or a bent pintle shaft.
-
If air passage has heavy deposits, remove throttle body for complete cleaning.
^ Inspect IAC valve O-ring for cuts, cracks or distortion. Replace if damaged.
CAUTION: If installing a new IAC valve, be sure to replace it with an identical part. IAC valve pintle shape and diameter are designed for the
specific application.
IAC Valve
INSTALLATION
If installing a new IAC valve, measure the distance from the tip of the IAC pintle to the mounting flange. If it is greater than 28 mm, use finger
pressure to slowly retract the pintle. The force required to retract the pintle of a "New Valve" will not cause damage to the valve.
