well Friday evening (6/27/12) my dealer called me and told me to bring it in for the repair, they said they would install a shield in front of the inter-cooler because it was getting too much airflow... sounds like a way to reduce power to an engine to me....

I dropped it off yesterday. we shall see...

 

I would think you would want more air flow through the inter cooler to maximize the turbo and would think by restricting it you would cause an overheat situation. But I'm no turbo expert or engineer. Good luck

 

I agree, heck if they are goign to put a "block off plate" in front if it why not just remove it. no air flow means no cooling.

 

That dealer doesn't seem to be all that bright.

 

they cn only do what Ford will pay them for, after they try this and if it still has a problem then they can get approval from ford to try other things. reason being is Ford has to pay them because the truck is under warranty. If you or I was paying them they could try what they want and we would have to foot the bill..

 

That makes no sense at all - seems to me that blocking flow to the intercooler is a great way to void the powertrain warranty..........

You sure they aren't TRYING to void your warranty so they can get you out of their hair?

 

It is a TSB put out by Ford. I don't think they would stand a chance in hell in court if they installed a part and voided my warranty because of said part..

my bumper to bumper warranty is now expired but this problem started 16,000 miles ago so it has been a pending case.

 

This sounds fishy..I've read plenty of posts about ppl wanting to or have installed lower valance grills to give a little more protection for the intercooler from rocks etc.. and they have been told by the dealers not to install them or remove them. The dealers reasoning is that blocking air flow to the intercooler could be grounds for voiding a warranty. Now this TSB seems to totally contradict that statement. I'd get a print out of that TSB just in case this "fix" goes sideways.

I don't understand how "restricting" air flow to the intercooler is going to prevent the truck from going into limp mode.

Good luck.

 

I'm not an engineer, but it seems that Ford, as well as other manufacturers, over engineer most parts of the vehicle. The payload capacity is probably a margin higher than what is stated, suspension, brakes, cooling, power train, etc, are usually overbuilt. Why is it that the intercooler is right at the threshold of performance and cannot tolerate even a slight decrease in air-flow before it causes issues? If the cooler is stout enough to ward off rocks so be it, but Ford had to realize that not all F150's live their life on the blacktop.

 

well......
on 6/29/12 my dealer called and told me to bring my truck info the TSB
on 7/2/12 i dropped it off with 37,109 miles
on 7/3/12 dealer called and said TSB was done and it was still having trouble on cylinder 4, so they swapped coils from 4 to 5 and the misfire also moved to #5. they ordered a coil.
7/5/12 Dealer called me back and said it was ready and all was well.
7/5/12 I picked it up with 37,160 miles. I drive the truck to my office and parked it there overnight, I had to drive my Tahoe home.
7/6/12 I hitched a ride back to my office. at lunch I took my truck fora 15-20 minute ride and was really optimistic all was fixed.. I left my office about 7:00 headed home and had only gone about 23 miles when the truck started running bad again and the CEL came back on... When does this cycle end?

 

Well I just hooked the truck up to the scanner and the cause of the CEL is a p0430 catalyst system efficiency below threshold bank 2...

 

If you have catalyst stopping up, it could be a leaky injector.

 

yep, and this is the second one they have put on it..
