    E-fans and CAI 5.4 2v

    Controller installed: Fans installed on the radiator: If that looks like a new radiator, that’s because it is. Turns out that the side brackets that bolt to the radiator had to be cut to make room for the fans. You can see on the left bracket in that pic, as I was test fitting. And don’t...

    E-fans and CAI 5.4 2v

    I finished up the FF Dynamics e-fan installation. Recall FF Dynamics is the only ones that made a “custom” e-fan for the downflow radiator in my EB. First off, their fan controller was questionable at best, so I went with the Flex-a-Lite variable speed controller. FF Dynamics kit came as two...

    E-fans and CAI 5.4 2v

    Good eye. For the decals, I carefully removed them from the old radiator cover with a heat gun and patience. Replacement decals seem unobtainable. I completed the job, and will follow up with a comprehensive write-up.

    Reman’d 5.4L 2v installation

    Affirmative. Also, their 3 year / 100,000 warranty is standard now. You pay for it whether you want it or not. But all-in, it’s still a great deal.

    Reman Engine Resources

    Powersource (AER) provided my reman’d 5.4 2v long block last summer for my ‘03 EB. Great to work with. $3,150 on my door step, no core charge if core returned within 30 days - I was a little beyond that but they weren’t concerned. More details in my thread here. I did the work, have put 10k...

    Reman’d 5.4L 2v installation

    Thought I would drop in for a quick update. I’ve put 10,000 miles on the new engine, and it hasn’t skipped a beat. I did run through a couple of idler pulleys, as they kept spilling their guts. Figured out I needed to chase the thread of the bolt hole in the timing cover in order to get the...

    New to me 2004 Expedition maintenance?

    Service the front and rear end, transfer case, transmission, PS fluid and brake fluid. Drop the pan for the trans and replace the filter. I picked up a similar high-mileage ‘03 Eddie Bauer last year - 260k miles - and when I dropped the pan to service the trans, the tell-tale yellow plug was in...

    Transmission identification

    I've got an '03 Eddie Bauer, 5.4 4x4, hatched 02/19/2003, and it's got the 4R70W. This web site here may help you narrow it down.

    P0171 and P0174 Bank 1 & 2 lean

    I replaced that - just used rubber heater hose. Works fine.

    E-fans and CAI 5.4 2v

    Received the FF Dynamics e-fans, just haven’t had time for the install. The fan controller that came with the kit did not impress me - a couple of relays, excessive wiring, and the instructions state to mount it in the engine compartment in a “cool, dry place.” Right. So I invested a couple...

    Not so Good Vibrations

    I’m keeping my eye on this discussion. I’ve developed a similar vibration that I have not isolated yet. Only between 70-80 MPH. Sometimes enough to make the rear view mirror vibrate enough so that’s it’s almost unusable. A cursory inspection did reveal what could be slop in the front driveshaft...

    Not so Good Vibrations

    That’s a pretty solid response. Input like that is appreciated.

    2003 overheating?

    Milky engine oil? That would indicate head gasket leak, which contaminates the coolant and can lead to overheating. When was the last time you serviced the cooling system?

    E-fans and CAI 5.4 2v

    I can do this thing you ask of me. Fuel burn has been anywhere between 14.2 MPG and 15.5 MPG. After installing the CAI, I logged 17.0 MPG. That’s all highway miles, but the prevailing winds have a vote when you’re driving a broad side of a barn down the road. Opening up the intake, headers...

    Electric Fan Install

    I know this is an old thread, but curious to hear any feedback or results on the FF Dynamics E-fan installation and performance / longevity.

    E-fans and CAI 5.4 2v

    I've done some research for FF Dynamics, and while there are some less than flattering reviews, they seem to be a legit operation. A sticking point I read time and again was their lack of communication, particularly no phone number to call. Reaching out to them via the "contact us" form on...

    Great minds think alike! Add to that Volant’s 15% military discount, and you can’t afford not to do it!

    E-fans and CAI 5.4 2v

    Thanks for the comments BigRed. I haven’t had the truck on the road yet to see / hear / feel any performance differences. I’m not expecting much, but just getting rid of the stock monstrosity was worth it to me, making the engine bay more user / maintenance friendly. I did confirm with...

    E-fans and CAI 5.4 2v

    The e-fans didn’t work out on the first go. I got the Felx-a-Lite 270, which is for my make, model and year; however, there was a different radiator during the 2003 model year. Through 12/04/03, the downflow radiator is what’s used in the EB. After that date, it’s the crossflow radiator. The...

    E-fans and CAI 5.4 2v

    Looking to free up dead weight, and increase the airflow, I’m installing a Volant cold air intake and Flex-o-Lite electric fans on my 5.4 2v. I’ve installed e-fans on several of my trucks over the past 20 years, and the improvement is apparent. I’m also looking forward to getting rid of the OEM...
