Information on New Throttle Body Gasket

A new gasket has been released for use in the above vehicles. The new gasket will seal better than the previous gasket.

When changing this gasket, be sure to check the bottom of the throttle body for any flashing. Any flashing that protrudes more than 0.50 mm (0.020") should be filed by hand. Use caution that the sealing surface is not damaged. Flashing in the areas indicated between the arrows is the most critical as it can effect the sealing of the upper to lower intakes.

Be sure that all surfaces are clean of any foreign material before installing new gasket.

Parts are currently available from GMSPO.
