    Fuel Grade discussion

    Use top tier fuel always. Regular or premium is your preference but you'll lose hp on regular because the engine pulls timing and reduces boost. Some people don't care but for me it was noticeable even at part throttle. You'll also get slightly better mpg on premium. For me it was like 1...

    engine coolant overtemp

    Did you bleed the air out of the system? Did it happen immediately after changing the water pump and coolant? The heater core gets air trapped in it. Ford Tech Makuloco has a procedure for getting the air out.

    CDF around 3

    The engine is spooling the turbos going uphill, while on the downhill there's less airflow so they aren't really doing much, even at higher RPM. The turbos will heat both the coolant and the oil when they get hot.

    Catalytic Converter Help - 2017 Expedition XLT 3.5 Turbo

    Any replacement cat would need to be CARB approved. CARB publishes the list of approved converters. The cat was probably contaminated from oil making it into the charge air. When I was in CA, the inspection stations didn't automatically check for replacement parts, but things may have changed. I...

    Oil extractors do not work on 3.5 Ecoboost oil pans

    A power ratchet makes removing the splash guard screws easier. Yes, you're still on your back. But it just zips the screws right out.

    Vibration cured!

    Nice to hear of a dealership actually addressing a problem rather than punting.

    Asking for a friend (Really) ...

    The dipstick is on top of the transmission, next to the exhaust. The transmission needs to be at operating temperature to properly check fluid levels. I haven't had any transmission issues so I don't know what would show up with a code reader, but you can probably search for 6R80 transmission...

    2022–2024 Expedition Limited/MAX buyer advice (HD Tow required, winter driving, prefer physical HVAC)

    Another thing to consider. I think the CDF drum issue wasn't addressed until the 2023 model year, so I would avoid anything older to reduce risk of transmission or phaser issues.

    2022–2024 Expedition Limited/MAX buyer advice (HD Tow required, winter driving, prefer physical HVAC)

    My recollection is that CCD only comes on trims equipped with 22" wheels. If that is the case, it may limit the selection of suitable tires for towing. Not sure how well CCD works if you go down to a smaller wheel. It's likely tuned for the heavier unsprung weight of the 22" wheel. But...

    New from Texas

    Congrats on the purchase. What are you towing? Search for the tips on weight distribution hitch setup previously posted here.

    Changed plugs and noticed this?

    The gaskets fail and oil seeps into the plug wells. You can check by pulling the coil and shining a light into the well. The torque on the plugs is very low. My recollection is around 133 lb-inch. You can get away with it for awhile, but eventually you'll want to replace them because the oil can...

    2021 3.5l EB consuming lots of oil

    PCV valve replaced? Oil on the ground? Smoke out the rear?

    Towing handling

    Load D tires and more pressure.

    Is an aftermarket intercooler really worth it for towing??

    Its boost causing the elevated temps. Have to use the lower gears. Anecdotally, an oil cooler helps because the turbos are really heating up the oil when they're running hard. All that heat gets dumped into the coolant.

    Valve Cover leaking

    The plastic covers crack, need to include the replacement cost.
