Filling Procedure

WARNING: This page is about a different car, the 2019 Chevrolet Malibu. However, it is still accessible from the selected car via links, so may be relevant.
    CAUTION:

    The procedure below must be followed. Improper coolant level could result in a low or high coolant level condition, causing engine damage.

    CAUTION:

    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.

  7. Install the radiator surge tank cap loosely (threaded on about one turn).
  8. Start the engine and raise the engine speed to 2500 RPM and hold it there for 40 seconds, then shut engine off.
  9. Remove the radiator surge tank cap and fill the radiator surge tank until the level is visible and stable.
