98 XK8 cooling fan speed

Had a slight themostat housing leak last week so I replaced the housing with the metal one,housing came from Jag w/ thermostat and all. Install went fine but the next time the car was run the twin cooling fans come on running on high and I mean high speed.Gauge indicates normal range,coolant is flowing,no air pockets. So next I replaced the cross over pipe that had fan temp sensor in it,again from Jag,and problem persists. When they come on I can turn on heater for a minute or two and they go off.Turn heater off and they come back on high.I took water outlet temp with laser and it read 165 *F,the water return read 145*F.No reason for them to even be running. The fans cycle thru low,medium and high as the engine warms up so I do not believe it is the fan control mod. I do not know the range of the thermostat as it came from Jag with the housing so I did not question.Also replaced the water pump 4 or 5 months ago with no issues.
car has 62K miles,no other issues.
At wits end.
