Important: Do not for any reason, insert a screwdriver or other small hand tools into the throttle body to hold open the throttle plate, as the wedge inside the throttle body could be damaged.
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 plate has a factory applied sealing compound. The DAG material is applied to the outside edge of the plate 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 in order to avoid damage.
Notice: Refer to Fastener Notice in the Preface section.
