Coolant Color

[grigr]

Hey y'all,

I got my FiST a few months back and while under the hood, I noticed that my coolant level was right at the Min point (the engine had cooled off for 3 hrs at this point). Per Ford, I should use Motorcraft Orange.

However, the coolant inside the reservoir is very clearly pink. I have no idea which brand of coolant this is. How should I proceed in refilling the resovoir if the coolant in it potentially isn't Motorcraft?

Thanks!

in my opinion, i would probably flush it out and fill the system with motorcraft coolant. doesn't hurt to give the car a nice flush

Pink is "universal" coolant and does have the same organic acid technology for anticorrosion, but is missing several of the things Ford requires for protection of the plastic parts in the engine. The Fiesta (and all Ford products since about 2012 or so) should use Motorcraft orange coolant.

Flush and refill with Motorcraft orange.

Unless you can find some new old stock, the Motorcraft 'orange' does not exist anymore.

The new Motorcraft coolant is a yellowish green color, but almost the same exact chemistry (with maybe some slight improvements?) as the older orange coolant.

Yes, I forgot that, even though a couple of years ago when they made the change there were several long threads about it on the forum. The new yellow Motorcraft can apparently be mixed with the orange too, though I probably wouldn't do it.

Can confirm. The new coolant is just called “Motorcraft Yellow”, and is theoretically supposed to be 100% compatible with systems that were previously filled with the Orange coolant, even mixing them.

If your coolant is “pink” it could be one of two things - either old orange coolant that turns pinkish over time, or “pink” coolant that’s kinda sorta compatible. Either way, your coolant is probably old and you should do a full flush anyway.

The big No-No is mixing traditional (inorganic) green/red coolant with modern “OAT/HOAT” organic acid coolants (every other color including orange and yellow), as the two additive chemistries with react and start forming sludge that will build up in the system.

Its not pink. The orange looks pink when inside the reservoir. New Ford coolant that replaces the Orange is Yellow and is fine to mix. You wont be able to get orange anymore.

Ford came out with a message that yellow is compatible with orange.
