guess no one wants to assist with my issue?
Hi, I'm new to powerstroke and also a noob to diesels... i have been researching here for the last 6 months iv owned my 04 f350... I had Deltas at 23* so i went ahead and got my egr delete (sinister) and oil cooler replaced... since then my scanguage2 at 65mph on flat over a 20mile drive with ambient temps of 105* my coolant was sitting at 215* and oil at 223*... I believe this to be to high and in this time i never heard my fan kick on... I then added to my scanguage the FSS (Fan Speed Sensor) and all im getting at 65mph with ECT at 211* and EOT at 220* was FSS at 420rpm... my question is this normal?
Nothing has been done to this truck other than oil cooler and EGR Delete...
Thanks Guys for all the help
Oh ok... Yea is there anyway I could test fanclutch without being out anymore money... Cause if I have to replace I need all the $ I can getI think so also but since ford has not published a chart listing fan speeds in relation to temps, or none that I have ever found. I would really like to see one. It is really hard to say for shure. I guess that is proprietary information.
By the way the my post 7 was meant for urban assault vehicle not to you. Sorry I forgot to click quote button.
you misunderstood my statement. basically, the fan is needed the most at a stop or low vehicle speeds. but at 65mph the fan will not play a big role in temps. I dont care about the rest, I dont care if you are a ford tech, most ford techs are the reason these trucks get f*cked up. I build race cars for a living and I know how motors work. I could take the clutch fan off of my van in 110 degree AZ heat and I promise my temps will not be high(overheat) as long as I stay moving on the freeway. as soon as I get off, it will boil like a motha F*cker. as far as other factors ford added, I dont care. How ford decides to kick the fan on is irrelivant to me. I am speaking about the effects of the fan at 65mph and only the effects of the fan at 65mph.And when the truck is stopped or slow moveing the engine quits generateing heat?
This is why the computer controlled fan clutch was developed, to provide a more reliable and consistant control over engine temps under all operateing conditions.
Ford chose to do this by useing an infinitly variable speed high volume fan force feeding air thru the heat exchangers as needed only when needed to reduce drag on the engine.
I am feeling too poorley today to get into a debate on this so I will let one of the other Ford techs with access to fords current information. Mebe M-chan 68 or dave or one of the others will chime in.
Basicaly the pcm compares more factors than just coolant to oil temps to turn on the fan.
I was thinking the same, but one of his post's states that the EGR is plugged in,,,so..Anyone else thinking that it might be that the EGR is deleted and he's running a stock tune? Or has my day been that long that I'm not thinking clearly? :hehe:
I agree with you. I have the entire time. I have been trying to tell you that I am not arguing with you. I am simply telling the OP that his fan may be bad but that is not the reason for his temps.The guys temps were not in question they were reasonable underr the circumstances.
Just his fan speed as designed by Ford seemed a little low could cause him some problems pulling a grade while towing.
Thats all I got to say. OP good luck.
