Engine Removal

Special Tools Required 

NOTE:
  • Use fender covers to avoid damaging painted Surfaces.
  • To avoid damaging the wires and terminals, unplug the wiring connectors carefully while holding the connector portion.
  • Mark all wiring and hoses to avoid misconnection. Also, be sure that they do not contact other wiring or hoses, or interfere with other parts.
  1. Make sure you have the anti-theft codes for the audio system and the navigation system (if equipped). Make sure the ignition switch is OFF.
  2. Disconnect the support struts from both sides of the pivot ball (bolted to the hood). Secure the hood (A) in a vertical position. Remove the right side pivot ball and install it into the lower threaded hole (B), then reattach the support strut.
    NOTE: Do not attempt to close the hood with the support strut in the vertical position, as it will damage the support strut and hood.
