Hey guys, I’m looking to do a coolant flush this weekend on the ST and I checked the supplement to find the exact coolant but I can’t seem to find it anywhere, even on fords website. I’m starting to think the product code may have changed. I ended up buying this from my local dealership, would this work?

The yellow replaces the orange.I got a gallon just like yours last week.Fiesta st fourm showed ford data that said mixing ok.Why would ford replace with coolant that would not mix?

If you don't want to mix the yellow, you can still get the orange from other manufacturers. I bought a gallon of Peak Original Equipment Orange a couple weeks ago.

Just wanted to make sure, better safe than sorry

You can safely mix them or flush with the new variant.

I flushed with distilled water, then put in Peak Orange.
