I noticed recently that the fans on my '06 V10 run on a very high setting all the time. They do not continue to run after the engine is shut off (a few seconds maybe). I replaced the temp sensor right in front of the oil filter housing. That made no difference. Apparently there are two sensors, but I can't find the other one. Temp readings on the gauge are fine. Does anyone know what might be causing the fan speed? Does the V10 have a thermofan switch? I couldn't find it in the usual spot (bottom driver side of the radiator). I'm really hoping not to have to go to the dealer.
