1. NOTE: The IAC valve may be damaged if installed with the cone (pintle) extended more than 28 mm (1 - 1/8 in). Measure the distance that the
valve is extended before installing a new valve. The distance from the idle air control valve motor housing to the end of the idle air control valve
pintle should be less than 28 mm (1 - 1/8 in). Manually compressing the pintle until the extension is less than 28 mm (1 - 1/8 in).
IMPORTANT: Use an identical part when installing a new Idle Air Control (IAC) valve. The IAC valve pintle shape and dimensions are
designed for specific applications.
On a new IAC valve, measure the distance between the IAC valve pintle and mounting flange. Use finger pressure to slowly retract the pintle if the
distance is greater than 28 mm (1 - 1/8 in).
2. Lubricate the IAC valve O-ring with clean engine oil.
3. Align the flange holes with the mounting holes on the throttle Body assembly.
4. Insert the IAC valve through the O-ring into the throttle Body assembly.
