Can you mix antifreeze

You can mix two different colors of the same kind of coolant without any problem whatsoever. Orange antifreeze should not be mixed with green antifreeze because they are not compatible.

You should not mix OAT based formulas with IAT formulas. Keep in min OAT based formulas are still a developing technology. There are some “universal” formulas that claim compatibility with other IAT. You can certainly mix it with more water, but of course, you raise the temperature you are protected to.

And you can mix it with other antifreeze, IF the main ingredients of both are the same. It is generally not advised to mix antifreezes. I am sure you could mix those without any ill effects. However, you may be able to get away with just the anti-freeze.

It has a little deodorant in it, and in the short term the tank may not get too smelly with the cold weather. Then you start noticing a sludge (jello as one person stated) in your coolant system. This could lead to clogged radiator and coolant system. Only mix the green with the pink. This can decrease the effectiveness of the antifreeze and can cause a brown gel like substance in your car.

This can cause your engine to overheat and it clogs up pipes and can cause engine damage. But here’s where you get into trouble when mixing different colors of antifreeze or different types of antifreeze. Car makers select an antifreeze chemistry based on the types of components (fittings, seals, tubing) of each particular cooling system’s internal components. The green and orange coolants do not mix. When mixed together they form a gel-like substance that stops coolant flow and consequently the engine overheats.

Traditional coolants (often green or yellow) generally use silicates, while new style (generally orange or pink) coolants use organic acids. Our specialist formula offers protection in all extremes, from -37°C to 129°C, and is available in both ready to use and concentrated form. Red antifreeze contains organic acids that protect engine parts from corrosion. Silicate (green) type antifreeze does not mix with red type antifreeze.

Never mix the two colors in a cooling system. The organic acids in red type will cause precipitation of silicates in the green type and corrosion protection is greatly reduced. Even the SAE says you can mix the two. Red type antifreeze is good for five years.

Q: Mixing red and green coolant in the radiator. That was an old type of antifreeze where the glycol lasts maybe three years max. So you’ve got to change the coolant maybe three years or every 10miles. The modern coolant comes in various different colors and red happens to be one of them. It often can last five years or 150miles.

So it’s a better antifreeze to use. On its own, coolant helps your car flush built-up heat out of its radiator to prevent your car from overheating. The antifreeze does not jelly.

Mixing them can lead to reduced effectiveness of corrosion inhibiting additives and thats all. Ethylene Glycol or Propylene Glycol are your choices.

If you have mixed the different base chemical types, you will have to flush the entire system. This is usually black, or dark gray. This can make it confusing when trying to decide which coolant you need in your vehicle. The different colors can mean different properties of the liquid.

The litre bottle has an easy pour spout, and the coolant itself will work in any car, van or light truck, guaranteed. It is never safe to mix chemicals unless you understand what the result should be beforehand. There may be incompatible chemicals in those coolants that produce something you do not want when mixed.

Toxic gases, etc) - Not likely, but very possible. You can obtain the appropriate coolant at an automotive parts supply store. If in doubt, ask a store employee to help you locate the correct coolant. Use a coolant exchanger to replace your Dex-Cool coolant.

A higher water to antifreeze ratio increases the ability of the mix to cool the engine, but the mix will not do very well in cold weather. How to Mix Dexcool With Regular Antifreeze. GM recommends coolant exchangers as the proper method to exchange the old Dex-Cool coolant in your GM vehicle with fresh coolant. Most automotive repair shops will be able to handle this service for you , and handle disposal.

Cummins made a blue dyed coolant which was supposed to be able to be mixed with red ELC or regular green polyethylene glycol coolant. However, some polypropylene glycol coolants are also blue in color, and will not mix with PEG coolants. Which is why mixing coolants is never advised… if you don’t know exactly what your blue coolant is,.

Mixtures with too much water may not provide adequate boil over or freeze protection. AFAIK, all antifreeze solutions can be mixed (same chemical class). As has been said don't mix them. The resulting mixture will not harm the cooling system. Stick with the colour antifreeze that was in there, even if it means paying a few quid extra for antifreeze from the main dealer.

Mixing Coolant Types Together Can Be Harmful To Your System - Add Pure Water In An Emergency Combining any of the above-referenced antifreezes together is not recommended.
