    how do I clear check engine light

    Is there a way I can clear the codes from the ECU so the check engine goes out? Trying to do this myself. I tried to disconnect batteries (both black cables) for about 10 minutes but no luck-- oddly enough, the radio did not lose the presets. Thanks david

    EGR replacement

    Hi, If the EGR needs to be replaced, how big a job is it? Do the EGR's on 2008 Super Duty Diesels get replaced often or can they be simply cleaned and reinstalled? David 2008 F350 6.4 140,200 miles.

    2008 F350 hits 112,000 miles

    I just hit 112,000 miles after about 11 months of use. I've been averaging nearly 16mpg (4.11 rear end). My truck is nearly 100% highway, and I usually drive about 60-65 mpg on the highway- I'm a slow driver. I try to keep the rpms at 2000, for good mileage. I don't pull a trailer but I...

    balancing tires on F350

    I have the stock steel wheels on my 350 dually. They seem hard to balance. A couple tire shops said they need a special adapter to get the wheel to center properly. They tell me to go to Ford. I called Ford and they say they do have the special adapter. Another Ford dealer said they are...

    Clogged drain at fuel filter

    I have a bit of debris blocking my water drain under the fuel filter housing (the one under the truck). When I rotate the drain, the fuel dribbles out very slowy. I pushed a small wire into the opening and the fuel dribbled out at a better rate- but not like it should. I noticed there are...

    types of coolant

    My 2008 6.4L F350 came with the orange type (extended coolant). I'm due for a coolant change next month (@100K miles) and I want to know if I can use any extended type coolant (like Prestone, Peak, etc) in the premixed containers. Anyone use a coolant called "Global?" I think Peak makes it...

    F550 Towing mirrors

    Will the towing mirrors on a 2008 F550 (or F450) fit on a 2008 F350 or 2008 F250? Are they the exact same mirrors? I have the 2008 F350 w/plain mirrors (electric) and wanted to buy a set off of a F550. Although the mirrors on the F550 are all manual, I think they should still fit only I...

    How are Wix fuel filters

    Hi, I'm thinking of going with Wix filters. I change my fuel filters ever 8-10 weeks and need a less costly substitute. Seems they are high quality and built to OEM specs. My truck is used for delivery and does about 10k miles a month. David

    got the "wrench" symbol today

    I changed out the fuel filters today (3rd time since new) and I may not have primed the fuel system correctly. When I started the truck it ran about 10 seconds then shut off. The wrench symbol was flashing. I tried to restart but the engine wouldn't start. I primed the fuel system a couple...

    Who else would do a good job changing my ATF?

    I have the 6.4 with auto tranny. The dealership wants a little over 200 dollars to do a tranny flush. Would an independent shop or tranny shop do just as good a job for less? Is there anything special about the tranny that makes it important to only have done at Ford?

    ATF change

    My owner's manual says to change the ATF at 30K miles on the Torqueshift tranny if there is an external filter and at 60K miles for the internal filter. How the heck do I know which one I have? I have an F350. Also what is the DANA rear end? How do I know if I have that type? Thanks

    Need real mirrors

    I need to remove the mirrors I have on my 98 F350 (the standard type) and replace with the bracketed type (I think they are referred to as "west Coast" style). Does Ford sell a plastic trim piece to cover the hole where the factory mirror is removed? Where are some good places to buy...

    2-stroke oil

    Is anyone mixing the Marine 2Stroke oil in their 6.4? I read about it all the time but not sure if it's OK to use in the newer engine. Sounds like something the 6.4 would agree with. I'd add it along with the Cetane booster I use from Ford too.

    DANA? Yes or No?

    How do I know if I have a Dana rear end? The owner's manual says to change rear end lube at 60K miles but for Dana rear end only. How do I know if I have that type of rear end? David

    I'm having a significant problem

    F350, auto, 6.4 liter. Under hard acceleration the engine runs horrible. It starts accelerating, then as the revs pick up to a certain point, it almost feels like the rev limiter is kicking in. The engine stops acceleration, the truck won't shift up, and it sounds like some of the...

    Fuel filters changed out this morning

    Changing the Fuel Filters is a simple job. A couple of folks on the forum gave me some tips and they came in handy so a big thanks for the help there. It's a pain in the butt to find a 36mm socket, but found one at NAPA for 17 dollars. Pricey, but it's cheaper than having the dealer change...

    I'm starting to use the newer Cetane/Fuel conditioner from Ford for my 6.4 liter. (PM22A) Anyone use this? I'm adding 6.1 oz per 38 gallons (derived from the 4oz to 25 gallon ratio). Is anyone using this additive? Do you like it? Anyone use a higher ratio? I'm thinking it won't...
