Color doesn't tell you what you really need to know. You can mix two different colors of the same kind of coolant without any problem whatsoever. But if you mix a significant amount of one type in with the other type, you're weakening your corrosion inhibitors (it happened to my brother, and look at the condition he's in now).


If you're just a bit low, I'd rather ad distilled water rather than mix coolants. You can read here on fords coolants. The coolant type is matched to engine block and internal material types, yeah you can probably do it and the sky probably won't fall, but if you can just add water until you can get proper fluids.


can u mix red and pink antifreeze? my car is running out. it's a 2010 toyota camry and it has, what it looks like, the pink antifreeze. it's like 33 dollars at the dealer, but then again. i went to kragen last night and they said it was compatible with the red. is it fine to use the red or are there any side effects to that?


For example, mixing green coolant with orange or pink antifreeze will cause the resultant mixture to gel into a thicker substance which doesn't flow as easily - clogging cooling system channels, radiators, and heater cores. Left uncorrected, the water pump will overheat and fail.


Mixing antifreeze? Ask Question ... and if you've got sufficient coolant concentration, you can simply add water. For what it's worth, apparently someone from the SAE (Society of Automotive Engineers) said you can safely mix up to 15% of the traditional coolant type into an organic acid type coolant without much of an effect on the corrosion ...


There are historical reasons why coolant/antifreeze comes in different colours – the colours related to what the product was made from. These days different brands use different colours for coolant and it doesn’t necessarily tell you all that much about what’s in your car, so using a product like Prestone which is guaranteed to mix with any colour of coolant/antifreeze is the safe way to ...


Volkswagen, Audi and other European vehicles use antifreeze that can be blue, pink or red in color. Most of these are available under the brand name Pentosin in 1.5-liter bottles. The pink and red are specifically designed for alloy engines and both meet the required G-12 coolant specification.


Ok, my car has pink coolant. I have a small coolant leak and have to put some in every once in a while. Well, I usually buy the kind that says you can mix with any color coolant, but I was on my lunch and in a hurry today and bought just the green kind.
