Removal Procedure

WARNING: This page is about a different car, the 2002 Pontiac Grand Prix. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: Do not remove the oil plug when the engine is warm. The engine should be cool to the touch approximately 2-3 hours after running. Removing the oil plug at warm engine temperatures can cause hot oil to overflow. This could result in oil loss and possible personal injury.
IMPORTANT: A small amount of oil seepage through the front seal of the supercharger assembly, behind the pulley is a normal condition. A buildup of belt dust and/or airborne dust can adhere to the thin oil film, which causes the oil seepage to appear worse than it really is. The supercharger assembly should not be replaced due to the seepage described.

However if the supercharger oil is visually dripping or puddling from the supercharger front seal, the supercharger assembly will need to be replaced.

  1. Remove the fuel injector sight shield. Refer to Fuel Injector Sight Shield Replacement (L36)  or Fuel Injector Sight Shield Replacement (L67) .
    IMPORTANT: To prevent contamination of the supercharger oil, clean the area around the oil fill plug before removing.
  2. Remove the oil plug (1).
  3. Inspect the level of the oil. The oil level should be maintained to the bottom of the threads in the inspection hole.
