Air intake, FPR spring, couple other questions.

[badyota82]

I just purchased an 06 F250 Lariat with 119k. Had the dealer do an oasis report and found that the EGR cooler and oil cooler, stand pipes and dummy plugs had been replaced at 93k.

Should the coolers be ok for awhile now? I need to get the coolant flush done, but not sure if I should do it myself or have a shop do it, as it seems hard to find a shop that I can trust to complete the job correctly.

Also, what cold air intake is the best for these trucks? I was thinking about the AFE stage II but there are 3 different variations of it.

My FICM voltage has been low at start up, lowest I've seen has been 30v, but then after driving for a short distance, it jumps up to almost normal, between 45 and 48v. Will this leave me stranded, will I have warning signs in the form of hard starts and rough runs or is the voltage reading the only warning sign??


And lastly, I read all about the BLUE FPR spring, but went to dealer and they can't seem to find it in their schematics, so do any of you guys that have done this have a part # for it or a suggestion on where to get it??

As a new 6.0 owner, I really appreciate the wealth of knowledge the forums offer!! Thanks in advance!!

If your reading FICM voltage I take it you have a monitoring device? The only way to know if your coolers are good is to see the ECT and EOT delta. The stock filter is the best filter and is good up to around 500 HP. No reason to swap that till later. Plus its a superior filter by far! As far as the FICM it will leave you stranded but will throw a code before it totally goes. When mine went it took about 4 days after it threw the code. I don't have the FPR spring number but you should be able to find it on Tousley Ford's website. Hope that Helps!

Your FICM is certainly suspect and judging by its voltage variations might decide to go at any time. It typically gives you trouble with the cold starts versus the hot starts. This doesn't mean that the cold start is the only time it decides to take the dirt nap, it can do that at any time.
If the truck is still running ok, get a rebuild from Quick Tricks auto, Innovative diesel or Swamps. They all have tuned FICMs as well.

Great info guys thanks!! As far as air filter, has anyone had any problems with the factory one sealing? Was looking at it the other night and it doesn't appear to have anything toward the bottom of the filter housing to hold the seal tight? Also another thong I forgot about, do these trucks respond better to 4 or 5 inch exhaust?

Thanks again sure appreciate the help!!

As already stated, leave the stock filter alone. The stocker has a "tab and slot" connection on the bottom that ensures a tight seal. No issues with that.
Go 4 inch, no need for the 5 inch.

Thanks for the info!! Trying to decide if I should go with the 58v FICM? is it worth the extra $?? Also, what filter system do you guys suggest for the cooling system??

I'd go with the 58V, and if you got the cash, get it tuned as well. For the coolant filter, I'd go with Dieselsite.
