Can you mix red and orange antifreeze

I have a 1. I've managed to defrost the pipes and now I am adding antifreeze. I bought blue. But there was also red pre mixed stuff and now I am doubting myself. As there was very little or no antifreeze in it I cannot see what colour was in it previously. Websites tell u not to mix the two but doesn't state why? What can happen if u use the wrong one? Colors mean less than chemical makeup. If you check your Renault glove compartment operators manual, the specifications pages toward the back will tell you exactly which type not brand or color your cooling system should have.

A lot of consumer confusion comes into play by the Prestone TV add where the guy is picking out antifreeze in a discount store. Another person tells the guy that "Prestone" mixes with all coolants. Nothing could be further from the truth. Take time to Google: Zerex Antifreeze. There are five completely different chemical types. None should be mixed with another.

Old fashioned green antifreeze or the Prestone in the TV add should not be mixed with any type of long life antifreeze. Eventually these two chemical types will create a "brown muddy" mess in the entire cooling system. It will plug heater cores and radiator cooling tubes. It should be fine as the colours are sometimes used as an indicator to age and effectiveness. Some change colour when they are worn out. Forget websites and get the stuff in! The differences is that the additives contain silicates, nitrates, nitrites, borates, phosphates or amines so that:.

All of this results in a considerably longer life span, whilst providing improved protection of all cooling system metals, including aluminium.

Benefits over conventional silicate based coolants are:. I have mixed them before with no problems but it isn't advisable. Your best bet would be to totally drain the system and put the correct mix in. Also have you defrosted the engine block and checked the core plugs have not popped out due to it freezing, also the radiator could be damaged.

It can turn to a messy kind of gel subsyance that makes engine cooling poor and can block smaller waterways in the engine. Answer Save. Country Boy Lv 7. What do you think of the answers? You can sign in to give your opinion on the answer. Who is Jack Timbo is here Lv 7.

Max Headroom Lv 6. You get purple anti-freeze :- They'll be fine. Ethylene glycol is the same no matter what colour they dye it. Still have questions?

Get answers by asking now.Have you ever wondered how pink, orange, blue and green engine coolants differ from each other? In days gone by, the colour of coolant was determined by the type of chemicals used to prevent corrosion — meaning you could tell a lot about the type of coolant used by its colour.

Next came Organic Acid Technology OAT coolants, whose chemical make-up offered better protection for cooling systems, and extended the life of the coolant. Newer coolants such as Prestone, based solely on the OAT chemical make-up, now offer a year or ,mile change interval thanks to their superior corrosion protection.

concerns with red antifreeze

Prestone is yellow, but many other coolant manufacturers use different colours. Similarly, if you buy a second-hand car, the colour of the coolant gives you no idea as to when it needs to be changed. Example — you buy a second-hand car and it has got pink coolant in it. You can see from the service record that it has had a coolant service within the last two years. But is it aftermarket or OEM spec? Will it last for two years or longer?

Can you Mix Different Types of Coolant?

If you use the product at the change interval you get complete peace of mind, as the coolant will offer protection for 10 years ormiles, which is likely to be the life of the car.

Is Coolant the Same As Antifreeze? What to Do if Your Windscreen is Damaged.Get the Car Talk Newsletter. Dear Tom and Ray: I have a question about antifreeze.

Many months ago, my trusted mechanic was making repairs to my Chevy Lumina. He told me he had to flush the radiator because I had added a different color antifreeze to my cooling system.

He stated that one cannot mix colors of antifreeze pink and green, in my case. Since then, he informed me that my head gaskets needed replacing. Could it be due to the little bit of pink antifreeze I added to the green?

And he said that under no circumstances should you ever mix pink and green. Unless you live in Florida. RAY: From an automotive point of view, however, it's a more complicated question.

The color in antifreeze is like food coloring. It's added by the manufacturer as an identifier. Prestone has always used fluorescent yellow, Texaco and Shell have always used green. So it gives you a hint as to the identity of the coolant's manufacturer, but it doesn't tell you what type of coolant it is, and that's the more important question. TOM: There are basically two types of coolant in the world.

There's "traditional" coolant, which is what we've been using forever. RAY: The difference is that the OAT coolant has rust inhibitors that lastmiles or more, whereas traditional coolants have rust inhibitors that only last 50, miles or so.

And if you mix the two types of coolant, nothing terrible is going to happen -- nothing is going to blow up or melt -- but a mixture of the two types of coolants won't have as much rust protection as either one individually.

So that's what was probably in your car, Jeffrey. There's usually a decal under the hood that tells you if your car came equipped with long-life coolant. Your mechanic may have noticed that the color was diluted with something else, and he may have assumed you mixed a traditional coolant with your OAT coolant.

So if, for example, you just top up your OAT coolant with a few cups of traditional stuff, nothing's going to happen. TOM: It's certainly not an emergency. As we said, nothing is going to break, burn up or melt. And even if the rust-inhibition properties were compromised, you could still go a year or even several years without any negative effects.

But it would be prudent, during your next service, to drain out a mixed batch of coolant and go with one type or the other. RAY: So that's the story on coolant color, Jeffrey. Color doesn't tell you what you really need to know.Lift the hood of a new Ford vehicle and you're likely to see a yellow coolant in the overflow jug and an interesting label on it.

In pictorial language it says "Do not use orange coolant; yellow coolant is okay. Sounds pretty straightforward, right? It isn't. Lift the hood of another Ford product in this case, a Taurus with the pushrod V6 and you'll see that same label, but the jug contains orange coolant. Wait a minute. Something clearly is very wrong. It cautions "don't use orange," but the factory-installed coolant is orange. Lift the hood of a Chrysler product and you'll see orange coolant in the jug and a "special engine coolant only" warning on the cap.

Isn't DexCool the special coolant, and isn't it orange? Yes to both questions, but Chrysler Group says don't use DexCool in its products. It's confusing, to say the least. The basic answers to what coolant to use where, and when, are pretty simple, but when you go past that, you're getting into some pretty complex territory.

And you have to know what coolant you're dealing with to be sure you're doing no harm. Longtime Motor readers know that the color of the coolant dye really is meaningless. Dye should help you spot a leak, but that's about it. But with these seemingly contradictory warning labels, you really need a basic understanding of what's been happening with coolant formulations and colorings.

The inhibitors make a huge difference, and they're what all the arguments are about. Didn't we talk about all these coolants last year?

You bet, and we'll probably be talking about them for years to come. Since last year, however, Honda and Toyota have moved strongly into extended-life organic acid technology OAT coolants. Yes, DexCools also are OATs, but these Japanese formulas are not DexCool, and the two car companies have indicated they absolutely, positively don't want DexCool-type coolants used in their vehicles.

Nevertheless, you have to pick something to install, and to top up with, and we've learned that the systems are not necessarily forgiving of some mixtures of different coolants. There are circumstances where an unfavorable mixture can cause an increase in corrosion. Taking these issues a step further, this year we've seen more cases that contribute to coolant confusion.

These days, it's all too easy to make a mistake. You have to appreciate a bit of chemistry about the various formulas. You've got to know in basic terms what's different about the different coolants-both conventional and extended-life types-and what it means when you have to pick one.

Yes, that includes a bit about the dye colors. You should know that the term "orange coolant" has come to mean a DexCool-approved brand but that doesn't mean it's really true.

If you make this assumption, you'd be wrong. It's what Ford's warning labels could be interpreted to refer to, so that label doesn't serve to clarify things certainly not when a Ford system contains a very different-non-DexCool, but orange-dyed-coolant. The discontinued Mercury Cougar was an exception; it did contain an orange coolant similar to DexCool.If we can't tunnel through the Earth, how do we know what's at its center?

A lady introduce her husband's name with saying by which can stop or move train what is that name.

No it will not but don't mix it with the orange. Asked in Jeep Wrangler What happens when you mix green and orange antifreeze in a jeep wrangler?

can you mix red and orange antifreeze

The difference between the two colors is that orange antifreeze contains a different type of corrosion inhibitor that has a much longer service life than silicates, phosphates and borates. Orange antifreeze contains organic acids that protect engine parts from corrosion. Silicate green type antifreeze does not mix with orange type antifreeze. Never mix the two colors in a cooling system. The organic acids in orange types will cause precipitation of silicates in the green type and corrosion protection is greatly reduced.

Asked in Chevy Malibu What happen when you mix universal green antifreeze with orange dex antifreeze in a Chevy Malibu? You can but then the mixture will turn into gel and your entire coolant system will be ruined.Orange antifreeze should not be mixed with green antifreeze because they are not compatible.

If mixed together, these two types of antifreeze form a cloudy substance and precipitation that can decrease the coolant's useful life properties. Although both the green and orange antifreeze are ethylene glycol-based, the difference between them is that they contain different corrosion inhibitor ingredients or additives. While orange antifreeze contains organic acids, green antifreeze has additives, such as silicates, borates and phosphates. The interaction of these different antifreeze types causes the formation of silicate precipitation, which has an impact on corrosion protection.

Another difference between these two antifreeze types is that orange antifreeze has a longer useful life that the green type. Orange antifreeze has a useful life of 5 years, whereas green antifreeze is good for up to 3 years. Orange antifreeze is referred to as an extended-life antifreeze. Home World View. Is Orange Juice a Pure Substance?

Are Orange Seeds Edible?Car makers use more plastic fittings in late model engines and the antifreeze base chemistry and additives must be compatible with the different plastics and seal materials. Even though some OEMs use the same type of chemistrythe chemical concentration and the formulations are extremely dissimilar. Different coolants may not adequately protect all types of engine, radiator, heater core, and other cooling system materials.

Antifreeze does several jobs. Of course it must prevent the coolant from freezing in winter. But its other main job is to prevent corrosion throughout your cooling system.

can you mix red and orange antifreeze

Modern cooling systems contain several different metals. The radiator can be made with aluminum or copper. The cooling lines can be made from steel or aluminum. The heater core is usually made from copper or aluminum.

The water pump is made with several materials, magnesium casting, steel impeller, and steel bearings. When dissimilar metals are connected by an electrolyte like antifreeze or water, you get galvanic action.

Electrons transfer from one metal to another, creating thin spots and pinhole leaks. Antifreeze contain anti-electrolysis additives to prevent galvanic action. But there are several ways to accomplish this corrosion protection. This is the conventional green antifreeze that uses silicate or phosphate inhibitor technology. Silicate and phosphate plate a deposit of material on all components throughout the cooling system to form a protective layer. Silicate and phosphate coat internal parts rapidly, so your system is protected shortly after a coolant flush.

These coolants use organic acid to eliminate electrolysis. Most are phosphate, borate, and silicate free. Organic acid technology reacts chemically with the metal surfaces to prevent electrolysis. This process takes much longer than IAT. If your vehicle used IAT and you flush and fill with OAT, it takes several thousand miles to establish corrosion protection.

Gates, maker of coolant hoses, fittings, and water pumps publishes several bulletins for technicians regarding the practice of mixing different types of coolants.
