Notice: If the IAC valve has 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.
• | Use the carburetor cleaner and a parts cleaning brush in order to remove carbon deposits. Follow the instructions on the container. |
• | Do not use a cleaner that contains methyl ethyl ketone, an extremely strong solvent that is not necessary for this type of deposit. |
• | Shiny spots on the pintle or seat are normal. The spots do not indicate misalignment or a bent pintle shaft. |
• | If the air passage has heavy deposits, remove the throttle body for a complete cleaning. Refer to Throttle Body Assembly Replacement . |
Important: If installing a new IAC valve, replace with an identical part. The IAC valve pintle shape and diameter are designed for the specific application.
If the distance is more than 28 mm (1.10 in), use finger pressure in order to slowly retract the pintle. The force required to retract the pintle of a new valve will not cause damage to the valve.
Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
Tighten
Tighten the screws to 3 N·m (27 lb in).
