coolent fan
what would keep that thing going all the time? Mine does, hot or cold. I know the "T" stat works because I can feel cold air and all the sudden feel really hot air. so I know its exchanging water and not over heating.

Yep.
It's the clutch on the front of the fan.

Re: coolent fan
Im assuming youre asking about a normal fan and not an electric fan. Not to be stupid here but a non electric fan is belt driven and will always turn. the clutch could be bad like they say . If you have an electric fan the temperature sensor is prolly jammed up thinking its hot so it stays on all the time or the wiring is off the sensor which causes the thing to stay on

Re: coolent fan
It's not hard to replace, but it is time consuming and usually brings a bit of blood letting with it. You have th remove the fan/clutch assembly from the waterpump/waterpump pulley and then seperate the clutch from the fan. If yours has a plastic fan be sure to inspect the fan for cracks at the base of the blades and/or the clutch mounting area. If you see any cracks go ahead and replace as this is the easiest time to do it, and if the fan comes apart during operation it can get really expensive...fast.
