Ever since I had the Hydraulic Seal changed (part # 90099-01581?) the radiator fan is always on, even when I start the engine without the a/c on in the morning. The revolutions of the fan seem to change with the engine speed. I am almost certain that the fan was not always on before, and would come on only intermittently. I have had the car at the local Toyota dealer several times for long periods at a time, but they seem to be unable to find the cause. Can you help?
