I also washed the k&n filter. That thing was filthy. Question about the fan clutch. When it is cold, should'nt I be able to spin it a good turn? When I spin it I get very little movement.
Not necessarily. When cold the fan is usually stiff for a minute or so when you start the engine. There's really no good way to test a fan clutch without an electronic tach and a strobe light.
The best "seat of the pants" test is to check the AC operation at idle. If the AC cools well at idle with the engine hot, the fan is doing its job.
When the clutch starts to get weak, the AC will wheeze out at idle. This will happen long before the engine temp is affected.
