Cleaning and Inspection Procedure

D

Clean the IAC valve O–ring sealing surface, pintle
valve seat and air passage.

D

Use carburetor cleaner and a parts cleaning brush to
remove carbon deposit. Do not use a cleaner that
contain methyl ethyl ketone. This is an extremely
strong solvent and not necessary for this type of
deposit.

D

Shiny spots on the pintle are normal and do not
indicate misalignment or a bent pintle shaft.

D

Inspect the IAC valve O–ring for cuts, cracks or
distortion. Replace the O–ring if damaged.

Measurement Procedure

D

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 IAC valve pintle on IAC
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.
