Radiator and Fan Replacement

WARNING: This page is about a different car, the 2011 Honda Pilot, 2010 Honda Pilot, and 2009 Honda Pilot. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
  • Use fender covers to avoid damaging painted surfaces.
  • To avoid damaging the wiring 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 any other wiring or hoses, or interfere with any other parts.
