Help me diagnose my problems!

My truck is a 2005 F-350 CCSB 4x4 automatic SRW. I got the truck this past fall, it currently has 63,000 miles on it, had about 55,000 miles on it when I bought it. The previous owners were an older couple that used it to pull their 5th wheel camper, but they bought a class-a motor home and didn't need the truck anymore. As far as I can tell, the truck is 100% stock and I believe it always has been stock. Shows up on the oasis report that the turbo was replaced under warranty. Other than that, just small recall work such as coolant level sticker and what not.

So...on to my problem...a few weeks ago I went camping. I was towing my 25ft camper down the highway and the fan kicked on, and it was loud! I had never heard this noise before. Shortly after that, I noticed the coolant temps getting higher and higher. I pulled over, the truck cooled down VERY quick. If I would baby the truck and really try to keep the RPMs down, it would be ok, but not if I would drive "normal". I am losing coolant, but it doesn't seem to be much out of the degas cap. It is a little moist around the coolant cap, and there is so e white residue, but I wouldn't consider it "puking". I notice no white smoke from the exhaust and my EGR valve is dry. I recently purchased an Edge Insight CTS, and my ECT/EOT deltas are around 6 degrees when cruising at highway speeds unloaded. I did find out that my FICM is on it's way out, but I believe that is unrelated to this issue.

Any thoughts as to what could be going on here? The truck drives just fine unloaded.

First thing I would do is replace the degas bottle cap. If its not holding pressure it will lower your boil point. Quick and easy thing to try.
What were the max temps that you saw?
And you might try looking into the manual fan switch. Kinda get proactive in the heat. Very easy mod.

I have a relatively new degas bottle cap from NAPA, think I should try a new one from the local Ford dealer? It seems like, with everything on these trucks (with the exception of head bolts), OEM Ford is best.

I didn't have my Edge Insight CTS on my truck a few weeks ago. I know the factory gauge isn't much better than an idiot light, but it came very close to pegging the factory coolant temp gauge.

I'll look into the manual fan switch mod, are there any good how-to write-ups on this? Maybe I could actually use one of my upfitter switches!


I had planned on removing my FICM this weekend to send to Ed for the "Ultra service". Do you think getting the "Atlas 40" programming is worth the $150, or should I just leave the factory FICM programming alone?

I went with the Atlas 40 and it reeley seems to wake up things. Turbo comes up a lot faster.
Cant run the fan mod on the upfitter cause your not supplying power to the fan your supplying a ground believe it or not. And ya just search fan mod, Super easy to do. Kinda surprised me how easy...almost felt cheated!
And ya if your peggin the factory guage you got a problem. You might also look into changing out the thermostat. Another easy thing to do.

one thought on atlas 40 tune... it mentions some warning about higher egts and you'll have higher egts towing normally. I would just get your ficam repaird to stock lvls then get your (possibly more serious and costly) coolant issue checked. Best bet would be to check your eot/ect while towing and see how close they get. if they get high like eot in 230s-250-s some clogging could be reason. the coolant puking could be caused by....
1/ coolant lvl to high,
2/ headgasket
3/ bad cap

check your coolant psi. you can do it yourself fairly easy, or have a diesel guy do it for best results. just my opinion though to help your truck.

good luck man.

A co worker just bought a 06 F350 and upon getting it delivered, the trick was puking really really bad.
Turns out it had some generic cap on it causing the problems

I haven't looked into how the upfitter switches work, but why cant they be used as a normal toggle switch (capable of making/breaking a ground)?

Even though my "normal" ECTs are around 188-192, I think that I'll put a new t-stat in just to be sure that isn't my issue. I'd assume t-stats are relatively inexpensive...

maybe I'll just keep the stock ficm tune for now, i suppose i could always send it back to him for the Atlas 40 some other time if i feel that it is necessary. i do have plans on doing a 4" turbo-back exhaust and the EGT add-on for the Edge Insight CTS before too long, which might make the Atlas 40 do-able.

i will hook on to the camper and see where my ECTs and EOTs are at

i dont think my coolant level is too high, but i'll make sure that it isnt.

i hope like heck that it isnt my head gaskets, but that sure has been a thought of mine. i'd really like to get away with the "one at a time" ARP stud replacement, but i cant do that if i have a blown head gasket!

i will get a new OEM Ford degas cap when i get my t-stat.

i will go to the local hardware store and make my own coolant pressure tester and see how that goes.

sounds good man there are plenty of home made coolant pressure test systems I made mine for like 40$ at ace haha. if its a headgasket it can be tricky to diagnose... Mine were only stretching at high rpms but never leaked till about 6 months after owning vehicle.


good luck and we'll help as much as we can.
