F350 PSD Fan Cluth

[Larry in Arizona]

I have a 2004 F350 PSD with tow package 6.0. I have had the turbo and the fan clutch replaced after pulling my new 5th wheel out of town and back again. It was a short trip...... It seems to run fine now but I have a fan that comes on when pulling up a steep grade. I think it is temperature related but the guages never move and the performance is good. Ford can't tell me what the fan sound relates to. Maybe ut us the fan cluth the replaced. I have never owned a diesel with a turbo and never pulled a 30ft 5th wheel. The tow pacikage seems to work great. It down shifts coming down the steep grades but I'm still a little uncertain about that variable fan. I'm sure those of you with more experience driving these rigs will be able to explain what I am hearing.

Thanks

The fan is supposed to come on at a certain temp to keep the engine and tranny cool when towing. it comes on more often to cool the tranny than anything thats why you dont see the engine temp move much. Take a look at your tranny temp gauge if you have one when the fan comes on and see if it moved

Thanks. I have a tranny temp guage but it never goes up. I guess the fan is doing its job. I just never heard it engage before and with the other problems I have had I was concerned.

The fan clutch almost never engages unless you are towing or sometimes have had the Air conditioner goin for a while. Thats probably why you thought somethin was up
