coolant flush

[fh4ever]

hi all,  newbie here.  I just bought a 2024 Edge, 30k miles, and I want to do a coolant change even though ford doesn't recommend it this early.  I have seen in the past where cylinder head gaskets (other make and model) have such small coolant passage holes that they plug up with corrosion over time.  I also know about the head gasket issue with the earlier 2.0...the ones that had the slot between the cylinders.  And their fix was to replace the groove with tiny hole drilled between the cylinders.  Well this seems to me a potential to plug with corrosion over time too just like the head gasket I mentioned above.  So at any rate, for my piecs of mind,  its every 30k miles for the coolant hange for me...  to ward off what I feel could be an issue down the road.

my question to you guys, first, does the 2024 have these small holes beween the cylinders?  Second, any high mileage 2.0s (with the tiny holes) had any known issues with clogging? 

I specifically bought the antifreeze from Ford so there is no question I got the right type.  Other than the need to "vacuum fill" the coolant system to "burp it", is there anything else I need to be made aware of?   

I'm old school and quite amazed how cars have changed to the point you really need to know what your are doing before starting work or repair on them.  Glad I found this site!

Concerning the 2.0L engine, sometime during in 2019-2020, Ford changed over from the wide slot to the small, cross-drilled holes. 

Because this change increased the amount of solid metal on the block deck between cyl 2 & 3, it provided a much larger surface for the head gasket to seal against. The new design has proven to be a permanent fix & I can't recall a single case of gasket failure.

 

As far as changing the coolant, if it were me. I'd get a copy of the Ford Service Manual for 2024 and read the procedure. 

$60 on Ebay, cheap insurance that will pay dividends for years.
