2008 Ford Super Duty

Comments

  • I just checked my mpg the old fashioned way today after getting the update two weeks ago. My mpg was 17.4 no towing, taking off very carefully and not exceeding 65mph. That is up from 13.5.
    I asked the guys at the service department why Ford didn't do it a long time ago. They said "We just got the program".
  • I got my programing done two days ago. So far the computer is saying I am getting worse mileage. I filled up last night and will be checking it by hand. It does seem to have a little more power but I will not be testing that much while I am watching the mileage under normal conditions.
  • I am going to be putting some type of air intake on very soon. Has anyone tried any that are out there? I am leaning toward the K&N because I have had those previously. Want any advice from someone who is running one on these 6.4L. I am also looking into changing the exhaust. I am not sure if I want to go with a cat back system or go with the expense of removing the particulate filter which involves a lot of electrical stuff. I am also concerned about doing a cat back because I have been told the particulate will not work correctly with out those finned tail pipes we have on these trucks. I just want to get air in and out faster and cooler. I believe these engines have potential they just have to have the right components to run with them. Any help or ideas will be greatly appreciated.
  • I put a S&D cold air intake on my 6.4, I wasn't able to tell much difference. I think if a person could open the exhaust up like you said would help alot. I have saw some DPF and catalytic converter delete pipes on ebay that have places for all the sensors to plug in. Of course it will void your warranty.
    I just bought a superchips cortex programmer for my 6.4. I haven't had it long enough to try it out much yet. I asked the mechanic at my dealership if it would void my warranty, they said it should be ok as long as I didn't turn it all the way up and try to tow 18 wheelers up mountains. But they did tell me not to mess with the exhaust, they said if it didn't have those finned tailpipes it would burn whatever was sitting next to it.
  • I plan on purchasing my first Ford F250 Super Duty this month.
    It is a 2008 I found today on a dealer's lot.

    On the window sticker , listed under Options , it states :

    JOB # 1 BUILD IDENTIFIER

    What does this mean ?
    Is it important ?
    ( pros and cons )

    Take Care

  • Job #1 is what they Ford referred as the first run of HD trucks for that model year. I purchased mine and it was a new 2008 F-350 and was called Job #3. They difference are minor modifications to the truck, i.e. the size of the front end air dam, or the rear differential standard gear ratio. I love my truck and haven't had one iota or trouble as of yet, with 11,350 miles on the odometer. I have a 6.4 diesel, 3:55 gear ratio rear end, two wheel drive, crew cab, long bed. No modifications, getting 14.5 mpg around town, and 11.5 towing a 12500 # RV.

    I have a 2007 super duty diesel.It has the same problem with the head gaskets that started in 2002 of which there are at least two ford TSBs out on this.I was told by the diesel tech where I bought my ford that it also happens on 2008 diesels.Ford dose not want to fix it and if you have one after market product on engine they will try to void your factory warrentee{they tried that with me except that there is the moss magnuson act of 1975 section 2302 that says they can not do that,]they told me that they were cancling my warrranty till I mentioned that actand they backed off.There are other messages in this forum about this,check them out in the 500 area of messages.
  • George here are my thoughts and I hope they help in some form. First thing is that I don’t want to talk you out of buying one, by any means. I just want you to understand as much as I can tell you. I have driven every truck out there since my toes could touch the pedals. The Super Duty (Ford) is the best. Dodge isn’t too far behind but I never settle for 2nd place. In my opinion Ford made improvements to the Super Duty or Heavy Duty every single year they ever made them all the way up to 2003. From then till now they have been going backwards. Although the 6.4L was a huge improvement over the 6.0L. With all this said it is not all Ford or any other manufacturer’s fault, they have had to work around so many government regulations. I do really want you to understand that the days of the Super Duty’s being the unbelievable machine are not quite what they were. The 20 miles to the gallon are gone. The unstoppable black smoke rolling and never ending power are no more. You can still do a lot of modifications to them but at a much higher cost and with much less results. But still if you want the best driving, pull anything and generally feel good about yourself when you are setting next to a kid with a jacked up F-150 wannabe, because you know you have em licked in every possible way the Super Duty is still that. Oh yeah and you can move anything that God has made moveable at the same time.
  • 9,016 miles on my 08. EGR valve went out. Check engine light came on and it had a loss of power not long after. Found out that it is a big problem with these tucks. So much so that there is a national back order on them. They pulled all of the old ones off the shelf and are building new ones. In the mean time, after a short temper tantrum, I'm cruising in my Pontiac G6 rental until they can get some in.

I have towed 7,000lbs for 600 miles with the Crewcab. Not bad on flat rolling hills, lacks on mountains but hey its a V-8. MPG towing 9-10 interstate.

    30,000 miles with out a issue. One problem, torn door seal.
  • dtdmdtdm Posts: 5
    I agree, why would you even think of going 95. The truck weighs in around 8k, so your at 15k+ with trailer. Think of the family in the car your going to kill. I have towed abit and have not had any issues. Dealer maintained and not one issue. If you take care of it and leave it the way it stock will take a beating.

    Yhea ask the dealer that question and see how fast they will void your warrenty.
  • dtdmdtdm Posts: 5
    How does the moss magnuson act of 1975 section 2302 interfer with a extend warrenty? The Ford extend warrenty states you will follow the maintenance manual. Why are people buying the 6.4 and paying almost $7,000 more for 3 dollar fuel and a smog filter that costs $3,000 and has to be change at 100,000 miles, which is not that long for a diesel. You can buy a 5.4 or 6.8 for less than a $1000 more than 5.4. I was told the 5.4 in the SD is not the same as the 5.4 in the F-150. I was told this by the dealer, he also said to make sure they put the right 5.4 oil filter on it. I guess theres a different between the 5.4's. Anyone know any thing about it??

    Jubliant is your leak coming from the over flow tank.If it is you might want to check if it is the problem of the heads lifting and putting compression in to water jacket.This has been going on since 2002 and includes 2008 .The heads on these trucks only have 10 head bolts compaired to 20 on 7,3 diesels.go to messages on diesels in the 500 range of messages,lots of info
  • skip21skip21 Posts: 16
    that act prevents any dealer from voiding any type of manufacture warrenty.When I told the dealer that after they said they were cancling mine they droped it.You would have to chect on how it effects extended ones but I belive it works the same.

    I am having this exact same issue with My F350. What is interesting is that I pointed it out to the Ford Store in Morgan Hill about six months ago and was told it was not an issue. Yesterday when I take the truck in for a recall the service guy opens the hood and the first thing he looks at is the radiator coolent and says "oh you have a leak". Let me see how much it will cost to replace the radiator. Bunch of scam artists.
  • Get ready for trouble. I have had 3 new radiators, new EGR valves and Coolers and the thing STILL doesn't work right. The regeneration process comes every 100 miles and no one knows how to fix it. I have 60,000 miles on mine and it breaks down all the time. Contacted Ford and they won't stand behind it. Prepare for a long drawn out tempertantrum if I were you.
  • There is a MAJOR issue with Ford and their radiators/EGR valves. My EGR coolers went out at 45,000, the EGR valve was completely clogged and they had to break it off in chunks to replace it at 60,000 miles. It still doesn't run right. It regen's every 100-150 miles and NEVER says complete. Took it to 1 shop and they said "nothing wrong" took it to another shop within 150 miles and they said there is something wrong. Sick of the whole truck.
  • its the egr valves and coolers, no codes will show up, ford tech's will look at you like a deer in headlights, but they know.

    There is a problem here, MAJOR problem.

    I have this exact same leak on my 2008 F350 6.4L. Took it into The Ford Store in Morgan Hill, California and they are telling me that it will not be covered under warranty. The truck currently has 41K miles on it and was in the shop for a routine service in December and nobody mentioned either the recall of that this seems to be a known issue with Ford 2008 trucks. Anybody have any advise as I dnt really want to pay $1690 to have the radiator replaced on a one year old truck.

    Ford's only comment is that they issued a directive last year to have all 2008 diesel trucks inspected for this issue but they are not issuing a recall as it only seems to be affecting the early 2008 models. Anybody have any recommendations?
  • They now say it is a bad processor and the word came directly from Ford. The processor is sending out these erronious signals. They have ordered the new processor and I am waiting on it. This sucks.
  • I've read all these posts. I have had the rad problem. About 35000 Km. My dealership knew the problem and had 12 rads in stock. The reprogam was done and all it seemed to do was show me when exhaust filter was cleaning. I had the driver's seat element replaced. My milage is between 13 empty and 25 L/100Km loaded, 4 wheel drive in 6" mud and idling all day (some days I shows 99L/100 km. It won't go any higher. It never shuts off for a few weeks at a time) It's a F350 long box crew and has over 1 ton of tools and pressure unit skid in the back ( don't tell Ford about the overload problem). I'm turning 37" tires with a 2 1/2 " lift. I have ran all the big three and I want to say this is the best damb truck I have ever had. I Just got rid of a 06 Dodge and my back and and hearing will never be the same. I have backtracked on lease roads to pull Chevys that were plowing snow or mud with bigger lifts. This truck has the most power (dodge had more torque but I hated shutting it off at a drive through for them to hear my order). This truck has more cab space then anything on the market. I drive this truck, and all that I have owned, like they do on the commercials. This is the best damb work truck there is and this is the first one that I am happy with in all the aspects of my job. I get tired of people complaining about things like injectors and milage. Dodge goes through injectors evert 15000 Km and brakes every 10000. Chevy acts like a plow out here and the front ends are in for repair all the time. These are the best trucks on the market for the time being. If you have a problem with milage increase your rates. You bought a truck for work and that is what this truck does best!
  • You shouldn't have replied to me, maybe someone else. I'm not fussin about mileage because I know I didn't buy a Hybrid. I owned four Internationals during the height of diesel prices. I love the truck. I shopped every make and model before making the decision. My father has a 350 and best friend has a 250 HD package. My only concern is what I posted and I was seeking others that may have experienced it. I was told the EGR problem was an epidemic by the Ford service peple. Now I'm bein told i wasn't the EGR valve it is a bad processor telling it that the EGR valve is bad. Meanwhile I had the symptoms of a bad EGR valve. Loss of boost/power. Love the truck but don't love the rental car!
  • I went thru the same thing, My F-250 had 41k miles also. Took it in for service and they said they had a few recalls 1 being the value that causes the problem, That recall was issued in Oct 2008 and said to have it replaced by Jan 31, as I did after the replacement my Radiator started leaking and they told me I needed a new one. I had it replaced at my cost. I pulled all service records and started with the service manager, I was able to produce all documents and the truck was fine until they started replacing things. I had to go owner of the dealer ship which I scheduled a meeting for, by being able to produce all documents that I followed What ford had recommended, he said it's not up to the dealership, but he did make calls to ford and Ford did cover this under warranty and I'm waiting on my refund at this time.

    Others, if your truck is under warranty, get this checked ASAP, if you are out of Warranty, keep all paper work, and plead your case properly, also everyone should file a complaint with BBB as instructed in the back of your owners manual. The more of us that do this the better chances are for a Ford Recall on the Radiator.
  • Ironically, I get the call today that the processor came in and was installed. However; They notcied my radiator leaking and have ordered a new one. It will be installed today and ready for pick up in the morning. The service manager said they have replaced over one hundred radiators at this small dealership. Unbelievable.
  • Picked up the truck today and it seems to be running well. Shift points are different but the power seems fine. Ford rep just happened to be there. He said that the radiator I received is the revised one and that will last the life of the truck. They had been replacing the bad ones with "bad ones". That is why they put two and three of them in because they didn't have the revised radiator to replace the bad ones with. With all of that, my hood was scratched and they will have to repair that next week.
    He also said that Ford will have it's own diesel motors begining 2010.

    I have heard very little about that new Ford deisel engine. Does anyone have any details?
  • I have a 08 6.4L with 21k miles. Had the software updates at 16k and engine ran fine. With 21k started the truck, white smoke, no power, felt like it was running on 2 cylinders. Shift points changed, mileage went in the tank and power was horrible. Managed to get the truck to the dealer; they were clueless for the first 2d and now claim its the EGR valve; and of course Ford has not issued the release date for the revised part so it was setting at the dealer. Picked it up and now its setting in my driveway waiting for parts. For those who have been here, how long did it take for the parts to arrive, did this fix the issue or is this just another ploy to get it out of warranty?
  • See my recently posted email; right now I am not exactly thrilled
