Anyone add an auxiliary fan to a e-clutch equipped Expedition?
Depending on which Which year Expy are you asking about? For my '01, I bought a kit (Troyer, I believe). The 2 fans came with radiator (AC condenser) mounts. They have a plastic zip tie like strip, a spring to keep tension without too much pressure, and some clips and such. Like this: Amazon...- Dustin Gebhardt

Anyone add an auxiliary fan to a e-clutch equipped Expedition?
I have added aux fans to my ‘01 and my ‘07. I used to work in Mexico and SoCal, so idling in the border crossing line for 2 hours while the air temperature is above 110’F brought my AC to its knees. For my ‘01 I bought a controller that used a radiator mounted thermometer and also connected to...- Dustin Gebhardt

Cylinder Head temperature sensor issue
Where are you testing the voltages? With everything connected, I'd backprobe the wires at the PCM and check the voltage as close to the PCM as possible. On my '07, the previous owner has sandwiched the wiring for the CHT sensor between the intake manifold and the head. 150k miles later, the...- Dustin Gebhardt

2000 Ford Expedition Transmission slipping
Might be a bad front pump or clogged valve body. My guess: the line pressure isn't building up fast enough. This causes your slippage when at a standstill until the line pressure increases enough to clamp the clutches down. When you shift from D to R and back to D, your valve body is...- Dustin Gebhardt

2007 Transmission clunk, squeak, grinding, 2H and 4A fails, 4L and 4H Drives
My first thought would be to see if the driveshaft going to the rear differential spins when you are in 4L or 4H and moving forward. If the rear driveshaft spins then your transmission and transfer case are likely okay (but not for certain just yet). If the driveshaft does not spin, then the...- Dustin Gebhardt

Expy fuel mileage
My '07 averages between 11.5 and 13.0mpg using an app to track actual mileage and fuel purchases. Note that this value is low by roughly 8% since I lifted her and put her on 35" tires. Prior to the lift, I'd be around the 14-15mpg range (highway).- Dustin Gebhardt

Ford Expedition 2004 5.4 2V AC Compressor Does Not Engage / I tried everything I know
I commuted into Mexico 4 to 5 days a week. Sitting and idling in the border line for hours at a time in the summer heat were miserable as my AC couldn't keep up. So I added 2 electric fans to the front of my condenser. They were powered through a relay, which got the on/off signal from the...- Dustin Gebhardt

Odd shake that went away
@whtbronco is on the right track. You state that the shaking happened after a highway run and acceleration, then stopping at a red light. Your engine likely high a slight increase in coolant temperature and pressure, which caused a slight leak. The coolant tee over the passenger side of the...- Dustin Gebhardt

Timing belt or rebuilt engine or new vehicle
Is the Jasper a new block? Are they using OEM parts? Likely a "no" to both questions. The Jasper will have a fresh set of bearings and rings, but the 5.4L engines don't often have issues with those to begin with. Personally, I'd stick with my engine and fix the ticking, which is likely a...- Dustin Gebhardt

Txv valve location
How high is "high". With the compressor off, the static pressure should be around 70 to 90 psi on both high-side and low-side ports. It's unusual to have both TXVs go bad at the same time. Sounds like a compressor failure to me. Replacing the TXV will require a complete depressurization of...- Dustin Gebhardt

2007 EL suddenly running bad
P0305, P0307, and P0308 are all driver's side misfires. This sounds like a failing timing setup or valvetrain. When was the last timing job done? Also, be sure to use Motorcraft plugs SP546X. Other brand or aftermarket plugs are common sources of poor performance. Likewise with...- Dustin Gebhardt

2004 5.4 misfire after intake swap.
The connections for my COPs and injectors were all dry rotted on my '07. The rubber rings inside the connectors were cracking, causing a bad connection with the COP or injector. I bought new pigtails for each and soldered the new connectors to the old harness. My misfires went away. If you...- Dustin Gebhardt

Power Issue
I had a U0101 code last week. Trans was in limp mode (locked in 3rd gear). Acceleration was dog slow. The wiring from my trans to the PCM run near the exhaust manifold and had melted. I pulled the whole harness (not a terrible job, about an hour) and repaired the harness with high temp wire and...- Dustin Gebhardt

Loud noise while accelerating
Highly likely this is the IWEs making noise when they try to engage under partial vacuum. They are supposed to engage when vacuum is removed and disengage with vacuum applied (2WD mode). During acceleration, engine vacuum drops. This causes the IWEs to partially engage. The teeth don’t quite...- Dustin Gebhardt

Starts then stalls 5.4
Sounds like a vacuum leak. Any check engine lights? If you scan it, do any codes show up?- Dustin Gebhardt
