Engine Oil and Oil Filter Change
Removal Procedure

Notice

To prevent leakage of oil filters, it is very important that you closely follow the installation instructions
listed below or engine damage may result.




      Important

      Be sure the vehicle is level during this entire procedure.

  1. Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle in General
     Information.

      Important

      In order to completely drain the oil from the oil pan internal baffling, the bottom of the oil pan
      must be level during the oil drain procedure.

      Allow a MINIMUM of 7 MINUTES for the engine oil to fully drain, once the engine oil drain
      plug and the engine oil filter are removed.

     Use the correct fastener in the correct location. Replacement fasteners must be the correct part
     number for that application. Fasteners requiring replacement or fasteners requiring the use of
     thread locking compound or sealant are identified in the service procedure. Do not use paints,
     lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These
     coatings affect fastener torque and joint clamping force and may damage the fastener. Use the
     correct tightening sequence and specifications when installing fasteners in order to avoid damage
     to parts and systems.

     Important

     Use a cap-type wrench, AC Delco OF17W or equivalent, or a strap-type wrench with swivel
     handle to insure proper installation.

  3. Install the filter by turning the engine oil filter clockwise. Tighten

     Tighten the engine oil filter to 30 N·m (22 lb ft).




  4. Wipe the engine oil drain plug with a clean, dry cloth.
  5. Install the engine oil drain plug. Tighten

     Tighten the engine oil drain plug to 25 N·m (18 lb ft).

     Important

     Allow a MINIMUM of 3 MINUTES for the NEW engine oil to fully fill the engine oil pan.

  6. Fill the engine with the proper type and amount of NEW engine oil. DO NOT use any engine oil
     additives in Corvette engines. For information on the proper type of oil to use, refer to Fluid and
     Lubricant Recommendations in Maintenance and Lubrication. For information on the engine oil
     capacity, refer to Engine Mechanical Specifications .
