Measurement Procedure

Idle Air Control (IAC) Valve





In order to install a new IAC valve, measure the distance between the tip of the pintle and the mounting flange. If that measurement is 28 mm or less, the valve need no adjustment. If the measurement is greater than 28 mm, apply finger pressure and retract the valve. The force required to retract the pintle on a new valve will not damage the valve, shaft or pintle.

NOTE: Do not push or pull on the IA C valve pintle on IA C valve that have been in service. The force required to move the pintle may damage it.

IMPORTANT: Use an identical replacement part in order to replace a valve. IAC valve pintle shape and diameter are designed for the specific application.
