REMOVAL:
1.
Disconnect the IAC valve electrical connector.
2.
Remove the IAC valve assembly and gasket, discard gasket.
CAUTION: 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.
^
DO NOT soak the IAC valve in any liquid cleaner or solvent, as damage may result.
3.
Cleaning and inspection:
^
Both original and replacement IAC valves have a special factory applied thread locking compound applied to the screw threads. If the valve
removed from the throttle body is being reinstalled, DO NOT try to remove any of the thread locking compound that may be remaining on the
threads.
^
Clean the IAC valve gasket sealing surface, pintle valve seat and air passage:
^
Use carburetor cleaner 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.
