    Solved: 3.5L EcoBoost Overheating while Towing or at Highway Speeds

    Interesting, thanks for the info. I'm not sure what package we have with our 2017, but so far we have not had any issues with overheating here where it gets to 110°. I will keep this in mind in the event we need a replacement.

    2021 Expedition XLT PCM and fuel pump failure!

    I have had severe failure codes on my 09 when the battery was low. So much that the car would start fine and idle, but it would throw all sorts of codes and not drive. Transmission would give me the wrench and things would happen. New battery resolved all my issues. In the future, if your...

    Start with foot on brake

    Huh? Accidental starting while working on an engine could be catastrophic for both the vehicle and person working on it. If your mechanic gets hurt as a result of the change then you are going to be held liable. . . Scenario, Tech is working on something in the engine and needs accessory...

    Start with foot on brake

    After thinking about this some more. The brake pedal does a lot of things really. It prevents unintended starting while working on the car and someone or something bumps the button accidently. It prevents pets from starting the vehicle if you don't want it started. It allows you to turn on...

    Start with foot on brake

    I do not know of a way to bypass the brake press requirement. Its programmed into the PCM, you might be able to get a custom tuner to disable it.

    Looking to purchase 2016 or 2017 4wd-questions on octane, turbos etc

    Thats true for the F-150, the expedition got the second generation 3.5 with the new Gen which is 2018. The expy is a little late to the party. We have a 2017, definitely no port injection on there.

    Expy 2010 rattle sound when 1st start in the morning

    Just because it takes a while to drain down does not mean its not leaking enough to cause low oil pressure up top. Even a small hole can make a big difference. These engines generally idle less than 20psi then you toss in a 4 or 5 psi loss due to the tensioner and you are in the danger area...

    Looking to purchase 2016 or 2017 4wd-questions on octane, turbos etc

    We are in AZ and have a 17 with 109K on it now. Had it for about a year and its been on 87 since day 1. No issues at all. Computer will learn for fuel quality and de-tune it so there is no risk of damage. Only issue we had was the front diff was empty and had to replace it. Other than that its...

    Expy 2010 rattle sound when 1st start in the morning

    I'm guessing you have it all back together now, but I installed a Melling kit with cast iron ratcheting tensioners and a high volume pump. kit did not come with phasers, those are still original. I would definitely put a high volume pump in there if its still open. Some people definitely do...

    2017 3.5 ecoboost turbo coolant lines: how snug are the lines in the jiffy fitting?

    Not sure, I haven't done this yet, but I would start it and check for leaks. A safer way is to pressurize it with a pump and check for leaks while wiggling it.

    Urgent request

    Swing by an auto parts store and have it scanned for codes. It could be a misfire, I would try to rule that out first. Like you said if its happening on the interstate it could be the trans heating up. If you have the ability I would check the transmission fluid level, its under the vehicle on...

    Asking for a friend (Really) ...

    If you are looking to save $ Take it to a smaller shop and have them drop a junkyard trans in it for a fraction of the cost. You can go to car-part.com and look them up. I found several low millage 6r80 transmissions for less than $500 on there.

    Asking for a friend (Really) ...

    Sounds like the fluid level could be low, or the fluid is toast. look up how to check the fluid level on the 6R80 transmission. Don't get burned too badly.
