Last I heard there was a tsb out on fans not kicking on during high demand. It was a PCM issue. No idea where I saw that though.

Hopefully, the Tech at the dealership can locate that TSB if it is out there?

I replaced the three radiator support air deflectors that were ripped and detached. Problem solved. This past weekend I looked at a friend's 2014 F-150 5.0L with 5000 miles and the passenger-side air deflector had torn loose from the frame. These things are a cheap cork material.

So it seems to me that it is near impossible to tow a grade at a reasonable speed? If I wanted to tow grades at 40 mph I would go buy a 97 f250 with a 460 gas motor in it. I feel that our tech has come far enough we should be able to tow grades at a reasonable speed (65) and not worry about overheating. I don't think we should have to buy radiators and CACs to tow less that the tow rating of the vehicle but maybe that is just me? I was in love with the truck until my towing experience. Debating now on getting rid of it...

next time jsut lock out 6th or maybe 5 and 6 and let the motor rev more at that will lower boost. it will move power back onto the motor rather then the turbos.

Not sure if you are talking to me or not Brute, but when I was pulling I was in 3rd gear at 40 mph down shift to 2nd temps would spike

ohh, well that'll do er. i try to get a semi good running start and gear down to 4th or so in my 5.0 and let it spin up to 3.5-4K rpms and she's rean just fine, but in a slow ( following semi uphill) situation that would be different. you got me out of knowledgeable answers. hope you get your problems solved! minus initital cost, if u can swing a 6.7 psd f350 that would really solve ur probs, but if its a DD with occ. twoing duties id try and work with what you have.

You'd be far ahead just getting a few aftermarket parts rather than trading it in.

I wonder if Ford changed the fan specs when they did the PCM reflash for the water build up in the CAC during wet weather driving.

That is what I am hoping, but I don't want to throw away 800 bucks on a radiator and then it still have the issues its having.
