Posted this in general tech with no replies, so I am trying here. On warm restart, radiator fans come on with ignition. Only happens with warm restart. Fans can be turned off when accelerator pedal is pressed to the floor. Sounds strange, but I have reproduced this response many times. Condition does not effect start up. Have looked into shop manual with no success. Anyone had the same problem, and solution?? Note that the coolant temp sensor has been replaced. Thanks.
