    Coolant system cleaners

    I ran it with the heaters on in the front and back until it was up to temp so that the thermostat would open. About 5 minutes on the highway would ususally do the trick. This would allow everything to circulate and mix well in all areas where the coolant runs. As far as the vacuum...

    2020 Expy Overheating at Highway speeds.

    The part number for the new thermostat was HL3Z-8575-B. A youtube video that I found in the internet is https://youtu.be/S0Kabry6I3M?si=3lGwi_vKNYOg-Qa6. You have to remove the air intake to get access. Whole thing takes about 15-30 minutes.

    OBD 2 port intermittently working with Scan tool

    The scan tool that I have does not have a battery. It is made by BlueDriver and I am sure it gets its power from the OBD port. After you plug the device in, it is supposed to get power from the vehicle and then you can use bluetooth to connect to a phone or other device, open up an app and...

    OBD 2 port intermittently working with Scan tool

    Let me explain better. Normally, when you plug the scan tool in, a blue light comes on indicating there is power to the tool. Then you connect to bluetooth on your device and you can scan the engine or analyze certatin data parameters that are monitored. When I plug my scan tool in, sometimes...

    Coolant system cleaners

    Good point. Only a moderate amount of cloudiness. No rust. Because I am retired and have a ton of time on my hands, I decided to do it anyway becasue I was servicing everything else on my truck including brakejob, brake flush, differential fluids (front and rear), transfer case, transmission...

    OBD 2 port intermittently working with Scan tool

    Hello. Looking for some direction. I have a BlueDriver Scan tool that works in my OBD2 port only intermittently in my 2020 Expy. I have tried everything. Works about 50 percent of the time. No rhyme or reason as to what makes it work or not work. I tried the same scan tool in several...

    Coolant system cleaners

    Are coolant system cleaners needed when flushing coolant system? Are they bad for the gaskets in and around the system? Is it better to do a flush with distilled water until clean, drain the system and then replace new antifreeze?

    Fluid spec source

    This is probably a silly question to all but I have been having trouble sourcing a good and reliable reference for the fluid specs for my vehicle. For example, for my 2020 Expedition has 60K miles and I want to change the following: - front differential - transfer case - rear differential -...

    Oil Catch Can in Cold Climates

    LokiWolf. Thanks so much for your response. Most of us DIY hacks really appreciate your wisdom on this platform. Regarding my drain lines for my RXP dual cannister setup, I dropped one line from each of the two cannisters and brought them into the driver side front wheel well and put on two...

    Oil Catch Can in Cold Climates

    Thanks for your input. Any experience with Team RXP twin can systems or have you heaard anything either way about this product? I put this sytem on my 2020 expedition. I think it works OK but if you installed it according to the instructions, it was very difficult to drain the cans because...

    2020 Expy Overheating at Highway speeds.

    Sorry for the late response. Somehow, I do not get alerts whenever someone responds. Regarding the temp showing up on the display, it shows up automoatically whenever the temp gets over 228F. When the temp drops below that number, the digital portion of the temp display goes away. I have...
