Installation Procedure

WARNING: This page is about a different car, the 2003 Pontiac Grand Prix. However, it is still accessible from the selected car via links, so may be relevant.

Important:  The oil pan gasket must be installed before the oil pump pipe and screen assembly.

  1. Install the new oil pump pipe and screen gasket.
  2. Install the oil pan gasket.
  3. Install the oil pump pipe and screen.
    NOTE: Refer to FASTENER NOTICE in Cautions and Notices.
  4. Install the oil pump screen bolts.

    Tighten 

    Tighten the oil pump screen bolts to 15 N.m (11 lb ft).

  5. Install the oil pan. Refer to OIL PAN REPLACEMENT  .
    NOTE: Do not run the engine until the oil pressure is tested. Running the engine without measurable oil pressure will cause extensive damage.
    NOTE: Stop the engine and remove the oil pan if the oil pressure does not build up immediately. Check the oil pump pipe and the screen for a clogged screen, damaged pipe, or a damaged gasket. Running the engine without measurable oil pressure will cause extensive damage.
  6. Inspect and verify that the oil pressure is within specifications.
