    Both engine support insulators 

    15. NOTE: Failure to replace the engine support insulator nuts may result in engine support insulator damage.
    NOTE: Only use hand tools when loosening the engine support insulator nuts or damage to the engine support insulator may occur.
    NOTE: The engine support insulator studs may come out of the insulator while removing the nuts. Install new engine support insulator studs if the studs come out of the insulator.
  15. Remove and discard the 4 RH engine support insulator nuts.
    16. NOTE: The engine support insulator through bolt must be discarded and a new bolt installed, or damage to the vehicle or engine support insulator may occur.
    NOTE: Only use hand tools when removing the engine support insulator through bolt or damage to the engine support insulator may occur.
