How hot is it down ther in florida ? Still above 70 during the day? probably normal operation if car is just sitting idling with no other source of airflow to cool it. Is the A/C also on?(or defrost- that defaults to comp. operation)
this problem came about when a heater hose went bad in back of the block i replced it the car was over heating its not now but the fans are at high speed like the computer gitting rong senser reading i was told it could be air in the system
That is a possibility. Some cars are set to default the fans to high speed if the PCM detects an open in the fan control(switch) circuit. Maybe something is not completely plugged in or got unplugged without knowing , when the hose repair was done. Hope I'm on the right track for you. Keep us posted. Thanks.
