Disappearing coolant?

[JamesV1]

Here i am 1 week in with a coolant issue lol.
Noticed to be a little low, next day even lower. With my work schedule i wasnt able to get it in immediately but once it was they said it was just needing to be burped.

Anyway 2 more days and it is once again low, as far as i can see no leaks and oil doesnt look milky. I dont believe these vehicles had any issue with consumption right?

Also i this may just be a extreme cold (-20F here) or maybe not an issue at all but my 1-2 shift seems slower than the rest?

Not uncommon to burp some coolant in the first 4-5 drive cycles of starting cold, getting to temp, and cooling down. After that no reason to lose coolant. Keep an eye on it for sure.

The coolant is pretty good in color so maybe they did a flush before sale and just hasn't settled.

They said the Trans is normal, just a bit sluggish when cold which I get tbh, its been pretty cold here and it seems better when warmed up

Alright coolant has now been filled 2x and still dropping at a decent rate. We were filled yesterday and after maybe 30mi of driving we are at the min mark. I was told no visible leaks and it passed the pressure test

Do you have white smoke coming from your exhaust? Did they do a combustion leak test?

You can also have the coolant tested in case you have a small head gasket leak.

Pressure tested and stated it all returned normal

I would look into the Combustion Leak Test.

Yeah the test will show if you have a small leak that a pressure test will sometimes miss. It tests for combustion chemicals in the coolant. Combustion chamber pressures are a heck of a lot higher than the coolant system pressure which is what they pressure test with.

Not sure of your mileage, but ever Ecoboost I've owned used coolant (1.0, 3.5, 2.7). I keep some in the garage and top them off twice per year.

Any chance it could be a heater core issue? I had a brand new car that had a pinhole leak from the factory. Of course the dealer I bought it from said there was nothing wrong. I took it to another dealer and they knew what the issue was within an hour.

Losing coolant could mean yr also burning it but let's not even get into that now and hopefully it will get straightened out !

Check both your turbo coolant lines. If you see a (volcano of dried coolant) at the turbo. You found your issue.
