    It seems the engineer could have made it easier

    I replaced the original intake manifold on my ‘03 5.4 because of a coolant leak at the crossover tube. I had used the Dorman unit. The biggest problems with the Dorman unit is that there are no screw sleeves/inserts for any of the components except the bolts that tighten down the manifold...

    Building Battery Cables

    Hey everyone. I’m in the process of determining everything I need to do a battery cable replacement on my ‘04 EB. I’m looking to eliminate the dimming effect that happens when multiple electrical systems are being used all at once. I do not want to do a Big 3 upgrade as I don’t want the extra...

    HELP!!! DIY 100% 71 yr. old disabled Vet ,looking to replace brittle vacuum hoses. Ford discontinued hoses per dealer, advice what to do..

    Not the best option but something else that could be done in a pinch (granted you have the materials) would be to heat shrink the old rubber. This would temporarily offer a protective barrier that will slow the separation of the degrading rubber. But if you have the time and means do what...

    New to me 2004 Expedition maintenance?

    Well then I retract my comment. Maybe I’m thinking of a different part on the underside of the 4WD.

    New to me 2004 Expedition maintenance?

    Like @smith627, I agree with @kep5niner on what to look at next. Replacing the transmission filter should definitely be towards the top. I replaced mine on my ‘04 about 2 years ago (19 years vehicle age) and found the yellow plug as well. It is easy to do on the 2WD models, I believe the 4x4s...

    E-fans and CAI 5.4 2v

    The amount of workable space you gained cannot be understated. Oil filter change should be super easy now. I feel like the stock shroud always gets in the way. I think it’s a shame though that FF didn’t make the kit more bolt on ready. And to make each fan separate? It’s good that you got it to...

    Wiper Arm Alignment

    Is the highlighted dot the factory alignment position for the blades? Might be easier to use that as opposed to measuring.

    Grille Guard and Milage -- And other diminishing factors

    Well I’m not sure what had temporarily contributed to such great gains. While it was a nice experience, I wouldn’t be concerned with anything as long as you are still within factory specs. Engine being tired at 102k, not likely, but that can’t be stated with 100% accuracy either. Best of luck to...

    E-fans and CAI 5.4 2v

    I’m glad mentioning FF Dynamics has provided an option you feel is worth your time and money. I’m definitely curious to see how it turns out when you are done. Would you mind calculating the MPG gains to compare before and after?

    Grille Guard and Milage -- And other diminishing factors

    When you were getting 18+ on the highway do you know if environmental factors or physics were helping? Environmental for instance could have been a tail wind. Or physics could have been a draft effect off a vehicle in front of you. Getting 16 is closer to factory spec, and as long as you aren’t...

    Grille Guard and Milage -- And other diminishing factors

    @Lost_Penguin_Expy, have the tires been checked for proper pressure? Not necessarily the factory specs but the tires specs? If they are becoming deflated you’ll get more rolling resistance. Which can lead to a drop in MPGs.

    E-fans and CAI 5.4 2v

    I only came across FF Dynamics when doing research nearly two years ago because I found out about the difficult radiator design for most kits. But I did not do any major research as I was and still am not ready to pull any triggers. Any information you get will be helpful for future decisions...

    E-fans and CAI 5.4 2v

    @kep5niner , FF Dynamics has an electrical fan kit for the down flow radiators on the 03-04 Expedition. It’s something that I have been thinking about for the same reasons that you mentioned. But as @whtbronco stated, the mechanical fan is robust and reliable. So that’s been my hold up. I’ve...

    P0172/75 to P2196/98

    Thanks for the advice on piecing together a new harness if needed in the future. It was quicker right now to go to the yard and find one. But I will keep that in mind if any future issues arise.

    P0172/75 to P2196/98

    I also took off a Fuel Pressure Dampener/Regulator and saw that it was the ‘dampener’ with no nipple. Which is odd, given the manual shows the ‘regulator’ with a nipple. At least now I know if I need this part in the future.

    P0172/75 to P2196/98

    @whtbronco, thank you again for all your input. I was able to figure out what the problem was with the codes. So I did have a vacuum problem after all, and it was nothing to do with the O2 sensors or Fuel Pulse Dampener. It was a vac line that went from the Vacuum Control Valve to the Intake...

    P0172/75 to P2196/98

    @whtbronco thank you for the response for a potential solution. I have (2) more questions now as it relates to the information provided. 1. Where did you get the OBD code sheet? I have the workshop manuals, but I don’t have any documents explaining what the OBD codes are. So far my searches...

    P0172/75 to P2196/98

    I have a 2004 EB 5.4 2WD with about 187K on the odometer. About 2 weeks ago (Dec. 18) I got a check engine light and when I ran the scan tool I got the codes P0172 and P0175. Generic codes stated that Banks 1 & 2 were running too rich. Ford Specific codes stated ‘Fuel System Too Rich...

    Reman’d 5.4L 2v installation

    @kep5niner, thank you for the information. Not something I plan anytime soon, but good to have the information for when it happens. Great job again on the build.

    Reman’d 5.4L 2v installation

    @kep5niner, fantastic work on what you were able to accomplish,:happy107:! I would like to do something like this in the future as well where I can put on some better exhaust manifolds and other engine parts (metal timing chain guides, cast iron tensioners, etc.). What did you use to connect...

    mileage/range

    Lower fuel efficiency in a large vehicle can have a variety of contributing factors. Some of things could be happening without a check engine light triggering because they aren’t bad enough yet. But here are things to take into consideration: What are your driving habits like? Do you...

    How many miles on your 2nd Gen Ford Expedition?

    182,000 on an ‘04 EB RWD, and still running. Bought with 80K already on it. I’ve had to replace the brake booster, intake manifold (stupid cracked plastic), spark plugs and coil packs w/ manifold, serpentine belt, AC compressor (found it it was a bad purge valve afterwards), fuse box, fuel...

    Best Heater Hose Disconnect Tool

    I had to replace the inlet hose behind the Heater Control Valve today. It was not a fun project, approximately 75 minutes total. I did use your tip to assist with the job. It didn’t take me 15 seconds unfortunately. I still had to manually push down and break the old tabs to get over the lip (I...

    Rear wiper delete

    How did you go about performing the delete? I live in an extremely dry environment and have rarely ever had to use the rear wiper. So a delete may not be a bad idea. Especially since currently the shaft more or less free spins when activated and doesn’t wipe. It not working is not the reason for...

    Wiper Issues

    Have you started with checking the fuses? And by rear wiper not working what do you mean specifically? Does the motor run but the blade stay stationary? Does the motor not engage at all? Do the sprayers have a filled reservoir to pull from? Not enough info is currently available to assist beyond...
