    2003 EB suspension maintenance

    Why not just replace the parts that are worn out and need replacing. Everything on your list can be verified though.

    2004 ford expedition need hose

    Goodness, you've swapped them twice now. I just a few weeks ago changed my coolant hoses for the first time and simply because 1 was starting to get a bit soft. Have you changed, completely flushed, your coolant? Coolant starts to turn acidic after about 5yrs or so I was taught. I started...

    HOSED BY A HOSE....AT THE END OF MY ROPE.

    I can't say for certain. It looks like a coolant hose to me, but I just replaced all my 2004 coolant hoses and that wasn't one of them. If it's causing codes what are they. The codes will help to identify the hose if they are related to it. Did the Expeditions have additional equipment to...

    Loss of spark after running for 5 minutes

    Well the CHT sensor is used by the PCM and it appears if the PCM doesn't get a signal within range it ca put the vehicle into limp home mode. Any codes present? My first thought though was a poor ground, there are a couple grounds under the hood. Now that I have thought it for a minute I'd...

    2004 ford expedition need hose

    Um yep, sure is. Wow, with that evidence there is no chance I would leave any of the existing coolant hoses in place. Changing all the coolant hoses under the hood is not real easy, nor is it cheap, but not doing it can ruin your day. I would also suggest flushing the old coolant out while...

    2004 ford expedition need hose

    Yep that's 1 of the heater hoses. May as well replace both of them. They are tough to get disconnected at the heater core(firewall). I ended up snipping out the part that catches the quick connects. I had bought a tool, but the one I bought was a total POS and didn't work despite hours of...

    2006 expedition King ranch how to put the vacuum lines back together

    I 100% agree manual hubs and a manual transfer case are far superior. They are sadly gone from the market. So the Integrated Wheel End(IWE) that Ford uses for hubs on these are vacuum operated. They use vacuum to disengage though so they fail engaged or as we used to say locked. I believe...

    Oil in coolant when purchased

    Maybe the coolant needed some extra lubrication. LOL

    Missing intake resonator

    @ 99WhiteC5Coupe During the winter I cover the upper grille and force it to draw air from the under the hood. The air isn't warmer on the interstate, just too much airflow, but it helps a bit with fuel economy around town to get warmer intake air when it's below 30 degrees or below. It also...

    Missing intake resonator

    No harm. I take mine out during the winter to force the engine to draw warmer air while driving around town.

    Wiring Identification

    Oh and while they are on top the EGR and EVAP vent valve are right hear the damaged wires as well.

    Wiring Identification

    I can't identify them with certainty. I can't even see that on my truck. I can, however, tell you the bundle appears to go down to where the O2 sensors are located. So there's a good chance that will resolve at least those 2 codes. If it was mine they would get repaired identified or not and...

    Replacing rear suspension pieces.

    The first time I swapped the struts on my 2004, air to conventional springs, it was done with traditional hand tools. It truly is no joke and that lower mount certainly is tight as can be. Well done doing it with hand tools. My second time swapping all the struts and more I used ratchet...

    Missing hose and broken hoses

    I would just throw a piece of 1/8" vacuum line on it to connect the broken plastic line to the heater valve.

    Missing hose and broken hoses

    I'm bettin' it's the vacuum line for the heater valve. The heater valve has no vacuum line connected. Here's some pics of the heater valve located near the firewall in the heater core hoses. https://www.rockauto.com/en/moreinfo.php?pk=380406&cc=1427756&pt=6860&jsn=676

    Missing hose and broken hoses

    As SafariGoneWrong noted this is the part number I used on my 2004 as well 4L3Z-3A788-AA. I think the lengths may be slightly different for the Expedition and F-150, but it'll fit just fine. Here's a diagram of the IWE vacuum lines that should help a bit. You'll notice 2 lines that are loose...

    Just replaced my IAC, EGR, and PCV valves..

    Hmm, yeah I expected and recall seeing some from the IAC. The EGR I don't and doesn't make sense to my feeble little mind. Time for more research.

    Just replaced my IAC, EGR, and PCV valves..

    I sure don't recall seeing any smoke from the EGR. There's a rubber diaphragm in the top there that should seal off the top half from the bottom half I believe. So I don't think smoke should be getting to that hole. Unless I'm wrong the vacuum line on top of the EGR will be able to suck...

    2003 - 2004 Expedition 5.4L Triton (2v) - Simple Coolant Flow / Heater Core Diagram

    That is certainly the easiest to read diagram I have see. Very nicely done and thank you. I agree it appears you could simply connection hose 1 to hose 5 and bypass both heater cores. This may very well be the single most helpful part of your diagram as people need to bypass temporarily.

    Replacing rear suspension pieces.

    Yeah with all bolts slightly snugged up to ensure there is no significant play I just put the jack under the strut and slowly lifted to the proper ride height and tightened it up. the lower strut mount is the main load bearing point on the lower control arm so to me it made sense. I'm not...

    Replacing rear suspension pieces.

    When I swapped my rear lower control arms I measured the fender height before hand. Then used my normal rear jack point which is the lower rear strut to lift it to the same height afterwards. Then tighten everything up. I also had a jack stand under the frame with just a tiny bit of space...

    Coolant reservoir empty after road trip. Can't find any active leak but see coolant inside some plastic hose covers etc?

    My thought was also the water pump, but the weep hole which is oddly located on top. All 3 times I replaced my water pump it was because I found dry coolant that had run down the timing cover. An extendable mirror can also help identify the source. The water pump is hard to see without a...

    Just replaced my IAC, EGR, and PCV valves..

    I just use whatever hose I can make fit the ports on my homemade smoke tester.

    Just replaced my IAC, EGR, and PCV valves..

    I was gonna suggest a smoke test. You might also consider simply replacing some of the rubber vacuum hoses and connectors. They are getting old and hardening and possibly not sealing really well. They may even be beginning to disintegrate. For instance I had to replace the heater valve...

    Timing set and a startup anomaly question

    1 last thing I kept forgetting to mention. I picked up Continental brand upper and lower radiator hoses from RockAuto. I simply chose those since they were available without additional shipping charges. Neither fit quite right. I cut a 1/4" off the lower radiator hose to get really close...
