    CAUTION:

    Phenolic spacer must be present to prevent galvanic/corrosive reaction and/or excessive temperature conduction between engine mount bracket and engine mount. Replace mount if phenolic spacer is missing or damaged. Failure to ensure phenolic spacer is intact and not damaged can lead to premature failure of engine mount and/or engine mount bracket.

    NOTE:

    Suspension components attached to the frame use Torque-to-Yield fasteners and must be DISCARDED and replaced with NEW Torque Angle Yield (TAY) fasteners. The frame to body fasteners are not TAY fasteners.

  1. Inspect the engine mount to ensure the phenolic spacer (1) is in place and not damaged.
  2. With the aid of an assistant, position and secure the new frame assembly to the support fixture.
