on a 2001 Lincoln LS when should the fan come on .
Are you talking about the electric fans at radiator? If so they should come on when engine temp gets to high or when ac is turned on.
well yes...if the operating temperature has been achieved....cold.....NO WAY..we must change the thermostatic control of your fan(s) if this is the case...you might start with the block temp sensor~ https://www.google.com/#q=2001+Lincoln+LS+V8+block+temperature+sens or
fan is not electric it is hydraulic
Oh ok. You know they have a conversion out now to change it from the stock hyd fan to an electric fan.
I'd assume always on , just as the better cars with v belts had
