2004 Dodge fan Clutch not engaging?

I have a 2004 Dodge diesel truck. I have never seen the cooling fans run faster than the speed it does at idle. I am used to hearing a roaring noise from the fans with my other trucks. Now, the temperature of the truck has never gotten past 200 degrees. Should the fan clutch cause the fans to run faster and make a roaring noise? How can I test the fan clutch as I don't want to buy a new one if it's not needed?

Oh!....What is the normal temp range that these trucks run at? I don't want to over heat the truck as it is still new to me!

anywhere around 200 is fine. + or - 10 degrees.

if you pull codes you might see a P0483, that is a sure sign your clutch is bad. You will have to pull codes, it will not turn the CEL on.

I had the same concerns on my 04.5, It was geting hot last summer so I changed the thermostat, flushed and put the zerex coolant as well as replaced the fan clutch and still never heard it kick In even when I switched the a/c on, I tested the wiring and everything seemed to be correct but still no fan force, I've had It well above 210, but never got any good answers, was hoping someone on the forum could tell me how to set It up to where I could hit a switch, sorry for the long answer.

If you do a little searching about it there a guy can ground one of the wires in the fan clutch wiring harness and it causes the fan to come on at 100% within about 30 seconds or so.

I set one up on mine when I did the auto swap nice piece of mind knowing that I can make it come on whenever I want.

On a side note not sure I have ever seen temps over 205 no matter what i'm doing.

The clutches are thermal as well as electric (really the electric side drives the thermal side with a heating coil, but semantics....) if the clutch gets hot enough it will engage.

If you're saying your truck is getting to the point of overheating and you're still not hearing the fan clutch tip on then, your clutch isn't working at all whether you replaced it or not.

Mine can be heard very faintly cycling in and out when the a/c is on at idle. I have never heard mine over about 15 MPH. I have seen a good 215*F while towing 70mph and it never kicked it. IIRC, people say it comes in at a little higher temp like 220* or so.... someone correct me.

I remember the thread about grounding the control wire for 100% duty. I always wanted to try this but never got around to it. How did it not set codes for that guy? It seems the ecm would set an overspeed code, or short to ground code for the control wire?
