Here I will be going over if you are able to mix pink and blue antifreeze.Personally I will never mix antifreeze I’d rather just put the regular coolant for the said vehicle. Sometimes you gotta do what you gotta do.

Pink Antifreeze

Pink antifreeze is an OAT(organic acid technology) which the chemicals made into it offered a better protection for cooling systems, and extended life of the coolant.

This kind of coolant is OEM extended life it is recommended for the use in (2004-present) Toyota,Scion,Lexus and other automotive and light duty vehicles requiring a phosphate based OAT engine coolant.

To get this antifreeze it should be in any car parts store or even online if you please make sure you get the correct kind of coolant.

Blue antifreeze

OEM extended life blue coolant meets and extendeds performance requirements. It protects coolant system metals against rust and corrosion and provides excellent high temperature aluminum protection.

Blue coolant has been formulated for the use in Infiniti,Nissan,Mazda and Mitsubishi vehicles. It is a long life anti-corrosion coolant meant to last a good five years in the cars radiator the color blue label has small differences for these rather than the one meant for Nissan and Mazda.

Mixing Pink and Blue antifreeze?

Mixing different engine coolants or using the wrong kind of coolant could result in the impair performance of the special additive packages; this can result in drastic corrosion inside of the radiator. Using the wrong engine coolant can gradually lead to the corrosive damage towards the radiator,water pump, radiator hoses and the cylinder gasket.

So when it comes to mixing Blue and Pink antifreeze it would most likely end up screwing up the radiator and potentially your engine if the car overheats.

Personally I wouldn’t mix these ever you could have major issues even if it is the last bit of coolant in your garage do not mix it! If you need more coolant just add water if you cannot make it to O’reilly or something. Water is mixed with the coolant so it is ok to put some in just make sure to mix the water with the correct amount of coolant or it will just freeze or just evaporate when it gets to hot in the engine bay.

Importance of coolant

If you ever run low on coolant or notice the temperature gauge go hotter than normal make sure to check if you have full coolant in the cars system.

If you do not know how to check coolant ask your mechanic how to or just read the owners manual comes in quite handy i’d say.

Once you have figured out how to check your coolant make sure it is above the minimum required if not. Drive to the nearest O’reilly and give them the cars make and model and they will find you what you need.

Then just pour in the correct amount of coolant and then you have nothing to worry about. Then you can just leave that coolant in your garage at home if you need to add more at any time.


Overall when it comes to coolants i’m not to keen on the idea of mixing coolants together when you could spend the 14$ to get a perfectly fine jug of the correct kind. In this of can you mix the Pink and Blue coolant unless you are ok with buying a whole new car then otherwise be my guest. If you want to mix coolants and the engine runs good for awhile then eventually big issues don’t say I did not warn you. Anyway put the correct kind of coolant in at the end of the day then you’ll have nothing to worry about.
