Well the gauge isn't very accurate as I have checked it before using torque pro.

Anyways, I think it is the fan clutch. Took off in the truck this morning and the fan want howling like it normally is first thing in the morning. I will pick up a new one and see how that does.

Thanks,

Matt

if it did howl and then calmed down in a minute or so then it seems fine so far. it show the fluid settled overnight and gripped it self hard but once working hard it loosened itself up as expected. at that point what you want is to see the engine get really hot and the fan will grip tight again and start howling indicating the clutch is reacting to the heat.

No, there was no howl at all from the moment I started moving. I do recal that I would hear the howl heading out of my neighbor hood and feel the drag on the engine. Nothing today. Even when I left for lunch. I will swap out the clutch and go from there.

lets put it this way. if you are getting the same effect on your temp gauge on a 110+day with a/c on and you stay around 210-220 or lower the fan clutch may just be fine. you have to get the engine really hot to get the clutch to get full grip on the fan. but by all means look at the front of the clutch and make sure the thermo spring end tab has not popped out of the tabs on the body that hold it in place.
