So I was at a gas station all they had was green coolant mixed 50/50 but the car had yellow coolant. The level in the reservoir was just under the minimum level and proceeded to top off the coolant which mind you I thought this was yellow coolant I was adding to the reservoir but was green thinking I just ruined the cooling system only a little over a quart was added. Is this okay until my next service to flush out and exchange which will be about the next 2 months? ---

Why not have the service done now and not wait two months? ---

what does your bottle of Green Coolant say it is? if it happens to be a universal coolant, then you are likely ok. If not, then you should have this flushed as soon as possible. \*Edited to remove my misspeak about yellow coolant not being ethelyne glycol, cause it likely is. 🙂 ---

All coolants are ethylene glycol. > **[Ethylene glycol](https://en.wikipedia.org/wiki/Ethylene_glycol)** > > Ethylene glycol (IUPAC name: ethane-1,2-diol) is an organic compound with the formula (CH2OH)2. It is mainly used for two purposes, as a raw material in the manufacture of polyester fibers and for antifreeze formulations. It is an odorless, colorless, sweet-tasting, viscous liquid. Ethylene glycol is toxic. Household pets are especially susceptible to ethylene glycol poisoning from vehicle antifreeze leaks. > Ethylene glycol is produced from ethylene (ethene), via the intermediate ethylene oxide.... Only Sierra is a propylene glycol [https://www.acehardware.com/departments/automotive-rv-and-marine/fluids-and-lubrication/antifreeze/8068090](https://www.acehardware.com/departments/automotive-rv-and-marine/fluids-and-lubrication/antifreeze/8068090) Which means you can drink it, and it won’t kill you.

> [@Tester](#): > > All coolants are ethylene glycol. All? Is Dexcool ethylene glycol? Granted, this Ford likely doesn’t have DexCool in it, but not all coolants are the same. ---

It’s the additive packages in the ethylene glycol that makes the differences in coolants. Tester ---

Most of the yellow I have seen is Prestone Universal which they claim can be mixed with anything. The Prestone is supposed to be a 5 year coolant but the green I have seen is only a 2 year coolant. My car has the pink Toyota extra long life which is supposed to have a 10 year life from thefactory but onlt 5 years after the first change. It is only made as a 50-50 mix. I wonder what you do if you live where it is really, really cold. ---

After work yesterday I finally had the chance to read the bottle it is not universal fluid and it does not does not state that it can be mixed. Is even a quart of the wrong fluid going to do excessive damage? However I fear that I’ll end up doing damage to the car before can get the flush and change can be done which I plan to do in the next few days hopefully. ---

It will be fine…I wouldn’t want a large portion in the system, but that little amount won’t hurt…especially in the short term.
