Oil Pump Assemble

WARNING: This page is about a different car, the 2003 Pontiac Vibe. However, it is still accessible from the selected car via links, so may be relevant.
  1. Lubricate the gears with clean engine oil.
    • The oil pump inner gear
    • The oil pump outer gear
    • The inside surface of the oil pump body
  2. Install the oil pump outer and inner gears to the oil pump body.
    NOTE: Fill oil pump cavities with petroleum jelly prior to installation. This will ensure that there is oil pressure immediately on start-up and will prevent engine damage.

    Important:  Place the drive gear and the driven gear into the oil pump body with the marks on the gears facing the oil pump cover side.
