I’ve got a 2017 Tundra 5.7 that just rolled over 100k a while back and took it in for a coolant flush and change then. Fast forward 5k miles I’m doing and oil change today and noticed my coolant is ORANGE not the OEM pink type.
Is this an issue? Do I need to dump it, flush and replace?
Looked at my records and the shop receipt for clues…it just said “global coolant” as the type they put in.

Any help/guidance is appreciated.

I'm pretty certain that the orange stuff is recommended for Toyota/foreign vehicles.

Someone please correct me if I'm wrong

The orange coolant is probably Dex-Cool, which is Ethylene Glycol.

The original pink coolant is most likely Toyota Super Long Life Coolant which is also Ethylene Glycol.

I was told by the co-owner of the local Napa, who worked in the parts department of a Toyota dealership for twenty years, that the pink coolant and the orange coolant are the same thing.

Call who did it, this colored coolant is a mess.
Jeep's are orange, duramax is orange coolant.

Ol' 69 and 83' chevy are green the good old coolant.

I've just heard of this organic stuff/ but researched it here
awhile back and can be harmful to system if not flushed before adding.
So no just topping it off with the organic.
One or the other.

Just changed the radiator in My Dodge last week, it had orange, so I refilled it with orange. My 09 Tacoma had pink I think but when I did a radiator in it I flushed it and put green in it. Everything else I have runs green, so I thought about putting that in the Dodge, but didn't feel like flushing it. They say you aren't supposed to mix them, but I've done it in the past with no ill effects.

My Skidoo has pink, no that I think about it, so I'm not sure if my Tacoma had orange or pink when I got it, I just knew I had something that had pink in it.

Thanks for the responses, much appreciated. Hopefully I can get it straightened out this week

… I don’t think this is really that big of a deal

… my oldest boy is driving my 2013 Tacoma with 250,000 + miles on it … original coolant… may have added some well water a time or two

Different color coolant have different additives. Asian pink coolant is the same base as dex-cool (which is most likely what you got) with more additives.

You will be fine to run it. Mixing colors isn't advisable but flushing and filling is fine.

Had a 1990 ford ranger with the junk 2.9, it would burn coolant, got stranded near the river one day with no water. Went and filled a jug up with river water and used a shirt to filter it haha

Your owners manual says which to use and its supposed to matter. Not that it wont cool but the PH level of it differs. The different manufactures use different ingredients to make say a radiator and some of those ingredients react negatively to certain things like say the wrong PH being too high or too low. Imagine the flux paste used to make your radiator is rated to be around certain chemicals and not others.

I went to a conference once and saw a presentation of Ford trying to figure out why there were so many radiator recalls. Turns out they saw there were clusters of them in neighborhoods, not spread out all over the country. Turns out certain car washes were spraying the straight soap concentrate and not mixing with water. The wrong PH on the outside of the radiator caused early corrosion and failed / leaked.

My 2015 F250 has a maintenance item that pops up on the computer that has me measure the PH level my radiator fluid. Thats why.

I have a gallon of clear.
Color blind friendly.

Have you checked the PH of
the different colors? Be interesting.
I try and keep an open mind,
but not so open my brains fall out lol.

I always mix with well water, but I've added creek water, ditch water, and even coffee before, when that was what I had. Almost anything is better than no coolant.

That's quite the truck for a kid. What did he do to earn the money to purchase it?
