Notice: In order to prevent damage to the sealing surfaces, carefully use sharp tools in cleaning the old gasket from the aluminum surfaces.
Important:
• DO NOT soak the throttle body in a cold immersion type cleaner.
The throttle valve has a factory applied sealing compound DAG material is
applied to the outside edge of the valve and the throttle bore to prevent
air bypass at closed throttle. Strong solvents or brushing removes the material.
To clean the throttle body following disassembly, use a spray type
cleaner such as GM X-66A or GM P/N 1052626. Use a shop towel
to remove heavy deposits. • The TP sensor and the IAC valve are electrical components and
should NOT come in contact with solvent or cleaner, as damage may result.
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.
