Engine Cooling problem
2000 Nissan Pathfinder 6 cyl Four Wheel Drive Automatic 115655 miles
----------------------------------------------------------------
WHEN IDLEING ENGINE OVERHEATS WHEN AIR CONDITIONING IS ENGAGED. WHEN MOVING OR AIR IS TURNED OFF IMMEDIATELY COOLS DOWN. RADIATOR AND THERMOSTAT ALL HOSES HAVE BEEN REPLACED. FAN SEEMS TO BE WORKING OK. DOES THE PATHFINDER HAVE ANY HISTORY OF THIS TYPE OF PROBLEM

when the ac is turned on the fan shoudl run faster OR the second fan if equipped should turn on! i would be checking for that first, if still has that problem could be a lean running condition or a cooling system in need of a flush.
