    Replaced factory RT1252 with RT1258 today

    I swapped whatever was in my 2019 with the RT1252 a couple years ago and it dropped my temps similar to what you're seeing now as well. I only touch 200 when it's really hot outside and i'm in stop and go traffic or running it hard. Otherwise, I hang in the 180-195 range...wonder if this newer...

    Turbo wastegate questions

    I've had these springs sitting on my work bench for months now. Just saw this thread and went out and installed. No tire removal or crawling underneath. I just turned the front wheels to get access, reached up in there and popped them right on. Rattle is pretty much gone, now just need to go...

    TSB 23-2250 - 2018-2023 Expedition/Navigator + Other Models - 10R80 Auto Trans + Others - Harsh/Delayed Engagement And/Or Harsh/Delayed Shift

    Update - The check engine light ended up being a bad O2 sensor. They replaced it and the weird shifting has gone away and things seem to be back to normal. I guess there's a chance the engine wasn't running correctly and maybe had the transmission shifting differently to account for that? Not...

    TSB 23-2250 - 2018-2023 Expedition/Navigator + Other Models - 10R80 Auto Trans + Others - Harsh/Delayed Engagement And/Or Harsh/Delayed Shift

    I recently had TSB 24-2101 done on my 2019 (which I'm assuming superseded the 24-2046) for shudder, delayed upshifting and general clunky when shifting in the lower gears. Night and day difference after having this done, but last week I started it up, took up and got the dreaded wrench. The...

    Sound Under Steering Column

    Same exact issue in my 2019. It would pop when turning. They found a broken clock spring in the steering wheel and replaced it. Went away for a while then came back and has been back since 2021... Had them look at it again and claim they couldn't diagnose it. I gave up for now but would love...

    CDF Failure - Dealer is Rebuilding Trans 2019 Expedition 41k miles

    That's great to hear your parts came in so quickly! I'm at about 48k on my 2019 and it's slowly getting worse. On a wait list with my dealer since the transmission tech is so backed up, but I'm fearful the UAW strikes are only going to drag this out even longer with parts now. Keep us posted...

    TSB 22-2475 - 2018-2021 Navigator - Grinding, Growling, Clicking Noise, Inoperative Power Steering Column During Telescoping-Raking Operation

    I wouldn't get too excited. I had this TSB performed on my '21 Navigator as they claimed this would fix the memory issue I was experiencing (would only recall the steering wheel memory position about half way to where it should be.). They did this TSB and it was good for about 3 weeks then...

    Factory battery life

    For what its worth, I just bought this charger and put it on my '21 Navigator (battery just hit 2 years). After being hooked up for ~4 hours, the light finally went green showing it's 80% charged. This was after a drive on the freeway for about 45 min. I'm convinced these just don't get fully...

    Factory battery life

    In my 2019, mine lasted 2 years. Auto Stop/Start quit working, so took it into the dealer and they determined the battery was bad. That seems to be the first sign it's going out. I just never noticed because like you, I turn mine off all the time. I forgot to one day and noticed it never...

    HVAC AC Smell on 4th Gens?

    So adding the elbow fixes the issue of water not draining out, but what's the solution if you've already got the smell in there? Has anyone tried spraying a can of evaporator coil cleaner in the drain hole, like this: https://www.lubegard.com/products/evap/ I've done this on an older F250 and...

    Headliner Repair?

    Did a quick search and didn't find anything, so asking here. I had a sharp object hit the ceiling over the weekend and make a small tear/puncture in a part of the headliner. Has anyone found a repair or patch kit that matches the color? I've seen a few things on amazon etc but hard to know...

    2018+ Fuel Filter location?

    Hard to tell from your pictures you posted, but where is it that you depressurize the fuel system? almost seems like it's inside the kick panel or somehwere in the back of the vehicle? As for the filter itself, is the skid plate near the tank? I haven't crawled under there yet...

    2018+ Fuel Filter location?

    So that sits inside the tank? The instructions almost make it seem like its accessible by removing a skid plate.

    Stealth Exhaust

    My wife's '21 Navigator has the same thing. Believe they're just small weep holes drilled to prevent condensation from building in the mufflers and creating rust. Hasn't caused a problem yet.
