The fan motor could have a bad winding. If so, it will not run reliably.
The fan motor is cheap and easy to replace. "MPost" > wrote in message ... >I can hear my cooling fan kick in when I pull up to my garage at night, >just before I shut the engine off.

That still doesn't explain why the car actually runs cool at times, though.

I found that when I was moving in traffic, my car stayed cool. If I stopped
at a light and the fan motor was not getting good RPM's, the enginre would get hot and the A/C would not cool well. It turned out that the internals of the power connector on my fan motor was messed up. If I wiggled it, the fan would get full speed. So I would hit a bump and the connector got good contact it worked good... next bump, poor connections, poor cooling.... Anyway, 1 hour later (including the trip to the part store) and $25, the problem was solved.

Turns out the problem was a bad coolant temp sender. Replaced both
(apparently, Saturns have 2), and the car's running fine again.
