    Reduction in MPG

    The car has run on Mobil1 synthetic all its life (I bought it new in 08), compression on all 8 cylinders showed 145 PSI + or - 10 psi, so I really doubt the rings are stuck or excessively worn. The oil has been changed every 3000 miles (I always thought this overkill, but it’s what was...

    Reduction in MPG

    I will give the Techron a try (nothing to lose). The car is a 4x4.

    Reduction in MPG

    Thanks for the suggestions, I have and still run Lucas fuel treatment so I can’t see that helping, I add 6 oz to every fill up. I changed the air filter about 400 miles ago, genuine motorcraft part, but it made no difference. I will get a fuel pressure gauge and check the line pressure, i did...

    Reduction in MPG

    Thanks everyone, I have been noting the mileage at every fill up and the amount of fuel I add, my calculated mpg and the displayed mpg match to within .3mpg every time. I did raise the car yesterday after a 50 mile trip and tried rotating the wheels, there was no noticeable drag and all the...

    Reduction in MPG

    I guess that’s possible, but would it really impact MPG by 20%? Don’t know how I can check if it’s that, I don’t have any garages that sell ethanol free gas within 40 miles of me to see if the MPG goes up using ethanol free.

    Reduction in MPG

    Hi everyone, I own an 08 Ford Expedition, have owned it from new, it has 240+K miles and nearly everything is still original on it. About a year ago (maybe a bit longer), I reset the fuel economy monitor (this car does not have an instant MPG, only an average MPG reading) and carefully drove the...

    2010 Limited | Windshield washer not working.

    I did the same thing when mine started messing up, removing the passenger headlight made it much easier to access the reservoir and pump.

    2010 Limited | Windshield washer not working.

    Does sound lIke the pump, if you can, I would try connecting a light bulb (not an led bulb) to the two motor wires and see if the bulb lights up when you try to spray water to both the front and rear windows. If the bulb lights up then it’s definitely the pump, but if the bulb doesn’t light then...

    2010 Limited | Windshield washer not working.

    If you didn’t know there is one motor and depending which way it turns (clockwise or anti-clockwise) it sends water to the front windscreen or the rear window. So if it is working on one window but not the other it is usually a broken water line between the pump and the window. If neither window...

    Coolant leak 2020 Expedition Platinum

    Glad you found it..

    2WD or AWD?

    Also if you use boat ramps a lot AWD is nice as the ramps get wet and slick with algae, AWD just makes it easier, otherwise dlcorbett was spot on.

    Coolant leak 2020 Expedition Platinum

    If the system is not pressurizing with the test kit, and you are not seeing coolant leak from anywhere, then it would suggest the leak is at a high point and you are just forcing the air trapped at the high point out of the coolant system via the leak. I assume that when you try to pressurize...

    Oh happy day

    Very lucky, I never seem to get the extractors to work that well

    2017 Expedition BCM Obsolete? Now what?

    Just a thought, but you might want to try fitting the load resistors that are sold with LED indicator lights to stop the hyper flashing, if you connect the load resistors in parallel with the the front indicator bulb, the system might see enough total current being drawn when the indicators...

    What would you do to go from 200k to 300k?

    When mine crossed 200k miles, I had all the wheel bearings checked front needed changing), check rad all the CV joints for free play and the suspension ball joints. I changed all the fluids, transmission, transfer case, differentials (front & rear), the brake fluid and coolant, got the AC...

    Headlamp wiring issues for 2013 Ford Expedition Limited

    If neither high or dip are working, I would suspect a problem with the ground wire. I would be checking that it makes good contact with the negative battery terminal. Measure the resistance from the black wire at the bulb connector to the battery negative terminal, if more than a couple of ohms...

    Liftgate Problem

    The latch requires a couple of amps to operate, your indicator light is lighting up to show current is flowing, but the bulb is only 1 watt or so, so it limits the current (acts like a resistor) to about 100mA (or less) which is not enough for the latch to operate. If you want to check the latch...

    Seat covers - real replacement covers

    Best of luck, whatever you go for, I have only ever used the seatshop and been very happy with their products, as you say they are quite expensive, but the quality and color matched very well.

    What is this??

    Where in Texas are you, there might be a local member that can help. As stated the air flow sensor might be as simple as cleaning it (a 10 minute job, but use mass air flow cleaner aerosol nothing else!) or it might need replacing given the age and mileage, they are not very expensive and easy...

    Importing a 3rd Gen to the UK...

    In case it gives you an idea, when I imported my 3rd gen expedition to the UK back in 2004 I just bolted some round orange indicator lenses from a mini to the rear lens cluster (didn’t want to make holes in the body), it didn’t look that great but met the legal requirements and passed the MOT...

    Dash Fan Setting 1+2 not working

    As stated, there is a resistor (it’s one unit but has 3 resistors inside) that controls the speed of the fan. The unit is prone to burning out over time, I suspect you need to replace the resistive unit.

    We have all done it at some time (popped a fuse without realizing) . Glad you got it fixed..

    Need Advice / Help - Random Bolt found in Transmission Tray when doing fluid / filter change - 2024 Expy Timberline

    Fingers crossed Ford does right by you.. I would be very concerned to find a bolt like that in my transmission sump, on the bright side, there doesn’t appear to be any marks on the bolt, so it doesn’t look like it has collided with any gear teeth or rotating components. Just a concern as to what...

    Multifunction switch or wiring problem

    The brakes are linked to the indicator switch because your car does not have independent orange indicator lights at the back of the car, it flashes the brake light on the appropriate side of the car. The only way the brake switch can know if it should illuminate both brake lights, or just one...

    Mechanics haven't helped... can you

    This is only a guess, I believe the 4WD system is engaged when the vacuum at the hubs is removed ie. atmospheric pressure is present. I believe the vacuum to enable the 4WD system is taken from the inlet manifold system, so when you put your foot to the floor, the throttle body open fully and...
