My 18 F150 had the orange and when I did the flush at 75K miles I converted to the yellow. My Mustang (22) has yellow. I had some leftover from my flush on the truck so I am good to go for a while LOL...

2019+ Fords now use yellow coolant.

Ford doesn't sell the Motorcraft orange coolant anymore.

You can change from orange to yellow with no issue and you do not need to flush the system.

Edit: The yellow coolant looks like a florescent greenish yellow.

So it would be ok to fill my 2015 mustang gt with peak orange ? I just got done changing out the oil pump gears and it goes in tomorrow for a tune. Need to get this thing running tonight

This is really fucking confusing. In the "important " note, it tells u not to mix it.

Motorcraft orange would be fine.
I do not know if the Peak brand orange is compatible.
One would like to think so, but until I was sure I wouldn't mix them.

I just used my Airlift kit tonight to change coolant over from orange to yellow (50/50 mix). It was very easy to do and worth the $140 I spent for the kit. I got all of the orange out that I could (heads were emptied when I did the Head Cooling Mod).

I drained the radiator tonight, drew a vacuum on the system, filled it with a gallon of yellow and drained the radiator again. I could see the stream of coolant turn from orange to yellow. I drew a vacuum on the system again and filled it with yellow. I’m GTG now!

No, it tells you not to mix it with any other coolants not specified as being compatible. In this case, Orange and Specialty green can be mixed or replaced with Yellow. An example of something not allowed is Motorcraft Gold, if you mixed Yellow with that it would make a big mess since it's a different chemistry.

I converted my car from orange to yellow over a year ago when I upgraded my radiator.

Oh OK. Makes sense now. I wasn't aware of other colors. Thanks.

Was it just to simple when everything took the old green coolant. Now I need to keep the old green for the classic car/truck, one for the jeep, one for the ranger, one for the stang, one for the gmc, one for the honda.

FYI, the yellow comes in concentrated and 50/50 mix form. premixed simplifies things a great deal.
