Installation Procedure


    Object Number: 143452  Size: SH
  1. Clean the BPMV gasket surface with alcohol using a clean rag.
  2. Install the EBTCM to the BPMV.
  3. Notice: 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: If the insulator nut was removed it must be replaced with a new insulator nut (3).

    Tighten
    Tighten the four mounting bolts to 3 N·m (27 lb in), then tighten to 6 N·m (53 lb in).

  4. Install the front EBTCM insulator mounting bolt.
  5. Tighten
    Tighten the EBTCM insulator mounting bolt to 14 N·m (10 lb ft).
