I have a Fiesta ST and it has what appears to be pink coolant in it, but it is actually the orange coolant

Thanks for the pics, it does say that they can be used to top off(mix) then.
i dont understand why the dealer couldnt produce something like that for me.
The parts guys werent trying to be unhelpful and were polite and helpful the whole time.
Why does it appear to be pink for you?
Is it pink in the overflow but orange when removed from it?
Man i sure miss just being able to go buy coolant without having to think about it.

I guess it's somewhat orange-pink, but my '13 came with orange and it never changed color. I suspect yours came with orange as well. The newer Ford yellow is compatible with orange. I haven't heard anything about the orange "clogging systems." I had my factory fill through 100K miles, and have since done two drain/fills (with orange). Zero issues.

Its weird, from the day i got this car with 6 whole miles on it the coolant has been pink.
I actually remember joking with my sister about it saying it was really transmission fluid.
Ive seen orange coolant in GM cars but never saw pink or change over to pink in them. It usually changes to brown or scales up the overflow and you cant tell what color it is or even if you have coolant in there.
If it does change color how long would that take for it to do that?
I cant seem to find an answer on that.

Anyways thanks for the replies guys.
Im debating on tossing this "quote" yellow coolant and picking up fleetguard pink stuff instead.

I personally would go with the yellow that is what will be used in my Fiesta ST.

The specs for your car in the owner's manual would be the code for Orange coolant yellow is the replacement for that.
Just call it pinkish orange and don't worry about it.

 

Here's a video going over the coolants that Ford just switched up in the last couple years:

Yellow just sounds like an improvement over orange

 

I didn't have the original orange coolant change colors before I got it flushed. It still looked orange after 5 years. I used my Ford rewards points and got the coolant flushed at a dealer. The dealer said they only use the yellow coolant for newer cars since it's better than orange (and compatible with orange). They have green for older cars since it isn't compatible with yellow.

I recently added coolant in my girlfriend's Compass and it's purple. I guess auto manufacturers like vibrant colors for coolant

 

They ended the pink/orange ish coolant now on some mt dew looking like stuff

When I got some thought they sold me the wrong stuff too hah.

Yes you can mix new vs the old so said my ford tech, I had the same question.

 

I topped it off again today with the yellow stuff since i was under the hood doing stuff.
Ill wait untill warmer weather to flush it and replace it all, by then ill have a better idea of what i want to use.
I will say that whatever is actually in there didnt coat the insides or thermostat with anything even after 6 years, not like the inside of a dirty fishtank look with particles floating around im used to seeing after this long on some vehicles.

 

I said i needed the pink kind since thats what my car came with

Prestone makes a universal coolant that claims to be safe with any other. I bought Auto Extra (cheaper). It says on the label:

• For all makes and models
• Add to any color antifreeze/coolant
• Guaranteed for up to 5 years or 150,000 miles

That was 6 months ago. Car still running.

Sometimes comedy writes itself.

 

After adding this yellow coolant, which was just topping off, to my car the coolant now looks very orange.

 

I have no proof but likely that Ford changed the dye from orange to yellow to ward off customer fears of any orange coolant which GM had fits with, it could gel up when mixed and even if used by itself and also wrecked some types of plastic. The GM orange and Ford orange are not the same thing. But people focus on the color and sh-t bricks over it, it would have damaged Ford sales of their own stuff. Think like they would.

The main difference in colors is the five year or standard one year thing and the old school one year lasts up to five years but nobody wants you to know that. It works instantly too as far as rust protection, the later 5 year depending on what is in it can take up to 6 months to develop full rust protection, and why I still use old school green one year in all my cars regardless of how new they are. That 6 month waiting period can put rust in your system.

When the rust protection takes 6 months to get to work some corrosion WILL happen and it can tilt the coolant color. I had orange way back when in a 10K '02 Focus and it slowly rusted to turn a rich shade of purple (!), the weirdest thing. When I went to drain it after a while I realized the color shift was mostly rust and went to old green and then no corrosion issues at all after that, the color stayed the same color.

I for one don't care about coolant color, it is only dye. In selling thousands of bottles of AFZ I found only one issue and that was with GM branded orange which DID cause problems enough to make them yank it to redo it. Nothing else out there will do that, the only other issue is the rust you can get if you use one of the modern 5 year coolants that still take 6 months to get up to strength, and several of those have now been modded trying to get away from that issue too.

I use old school 1 year green and no issues at all. Got 4 cars with it in them for years now and fine. One car has like a 7 year load in it now.

 

Flushed the coolant today. '13 since new, 126k miles. first flush. The color was an orange-pink color surprisingly. I decided to flush when I noticed the color a dingy appearance in the reservoir. The reservoir is clear because I replaced it a couple of years ago, small crack and leak. Replacement is Prestone concentrate, all makes, models and years, 10 year 300k mile warrantee (for what that's worth). Color is pea green. Didn't change the thermostat, or remove it, but drove several miles each of 4 flushes. Last flush just a tint of color. Will plan to do it again at 200k miles.

 

Maybe its been awhile for me doing this kind of work and im overthinking things but looking for some advice on this before i proceed any further, any input will be appreciated.

So i go to change my bad thermostat today and when to stop at the store to get some coolant since following the correct procedure i would have to drain most of the system to install it, basic stuff ive done before plenty of times.
They didnt have anything but the storebrand green stuff so i decided to hit up the dealer instead as it is on my way to work.
Get to the dealer and ask for some 50/50 coolant and explained what i was doing to the guy, he goes back and brings me some kind of yellow coolant out.
I said i needed the pink kind since thats what my car came with.
He says they never had pink coolant in their cars and i must mean the orange kind, which they dont use anymore as it was superseded with the yellow kind now. Apparently the orange stuff clogs up the system, like GM cars with the dexcool stuff.
I explained to him that i purchased my car brand new, and the coolant in the overflow was then and still is now pink and has not changed in color or tone after 6 years. The overflow tank is still clear and doesnt distort the color like on many other cars after a few years.
I asked him if he could show me something explaining the revision on the orange to yellow, which he did.
Now no one could tell me or show me anything official if it was safe to mix these two, the bottle said it wasnt unless by manufacturer recommendation, since i wasnt going to drain and fill the entire system at this time since i only wanted to replace the upper thermostat because time constraints and its too cold to be crawling under the car for doing the in block one.
I purchased the yellow coolant since something is better than nothing and i needed to get this thermostat done asap.
Replaced the thermostat without loosing much and decided to top it off with the yellow stuff only to see the stuff in the bottle is green. Poured it into the overflow and is light transparent green. Ugh. Didnt need much anyway will rectify later on.
Made sure everything was good no leaks and called it a night since my heat finally works now.
Spend some time lurking around the internet trying to get an explanation on the pink coolant thing and see everthing from "its all in your head and likely originally orange and changed color" to " it is oem pink like industrial, european and asian cars have".
No one states how long it was before their coolant changed color.
Now im at an impass and dont want to proceed further on this as it is untill i get some clarification on some things.

Now,
Firstly, has anyone else here originally had pink coolant in their system, or was it originally pink or changed pink from orange?

Secondly, Can someone here advise me or have some offical source that these orange and yellow coolants are able to safely mix together?

Is there a stat in the block too??? 👀

 

Yes, at the front left of the motor.

 

'Got another car im working on eating up my free mechanic time........'

Man I know THAT feeling...........constantly shifting priorities.

 

Id like to get done soon so i dont wind up getting stuck driving it with snow on the ground.
