The purpose of using an antifreeze is to lower the freezing point and increase the boiling point of the coolant. The key difference between red and green antifreeze is that red antifreeze lasts longer than green antifreeze. An antifreeze contains ethylene glycol and propylene glycol as the bases.

Besides, can you mix red and green antifreeze?

It often can last five years or 150,000 miles. So it's a better antifreeze to use. Now, if you mix them--they are not supposed to be mixed--but if you mix them it's not like mixing an acid and a base and you are not going to have and explosion or anything like that.

Likewise, what happens if you use the wrong color antifreeze? Mixing different engine coolants or using the wrong coolant can impair the performance of the special additive packages; this can result in increased corrosion to the radiator. Using the wrong engine coolant can gradually lead to corrosion and damage to the water pump, radiator, radiator hoses and cylinder gasket.

Also to know is, what do the different colors of antifreeze mean?

The color of healthy engine coolant is green (for ethylene glycol) or orange (for Dexcool). A rusty color indicates that the rust inhibitor in the coolant has broken down and it can no longer control rust and scale buildup. A milky color indicates the presence of oil in the system.

What brand of antifreeze is red?


APPLICATION Asian automotive and light duty vehicles requiring an OAT engine coolant.
VEHICLE MAKES Lexus, Toyota, Scion
FORMULATION Ethylene glycol based. Silicate, borate, nitrite and amine free

What happens if you mix red and green?

Mixing red and green results in a brown or gray color. The exact shade depends on the ratio of the original colors and the amount of pigment present. In this case, the primary color red is added to its complement, green, which is composed of the other two primary colors, yellow and blue.

Does the color of antifreeze matter?

The truth is, color is not a reliable predictor for what type of coolant you have. For example, OAT coolants are usually orange, yellow, red or purple. Then the older IAT coolant is green. Coolants that manufacturers sell can confuse matters even more, like Honda's blue coolant.

Why is some coolant red and some green?

Antifreeze: Red or Green? While it is ethylene glycol EG) based antifreeze, the concern with mixing comes from the fact that there are very different chemical inhibitor packages in use. Most leading technologies will work very well when used as intended, typically at 50% in good quality water.

Can red and blue antifreeze be mixed?

The older G12 coolant will not mix with G11. However, G12+ will mix with G11 just fine!! Assuming VW coolants being used of course.

Why are there different colors of antifreeze?

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. Older coolants that used Inorganic Additive Technology (IAT) were usually blue or green in colour.

What happens when you mix pink and green antifreeze?

Also, if you are currently using Prestone Extended Life 5/150 Antifreeze/Coolant in your car's cooling system, and you add a conventional antifreeze/coolant, you will lose the extended protection. The pink coolant in her Jetta is not Dex-cool. It is called Pentosin and mixing it with the green stuff will cause trouble.

What do you get when you mix green and pink?

Pink and Green mixed together make a gray color.

Is there a special antifreeze for diesel engines?

Our special formula for diesel engines acts as a complete supplemental coolant additive (SCA), providing 100% protection from cavitation, corrosion and electrolysis. Diesel Super Coolant utilizes reserve alkalinity to maintain safe pH levels to safeguard wet sleeve cylinder liners from erosion.

What color of antifreeze should I use?

For the rainbow of colors of HOAT, your only substitute is the yellow or amber global antifreeze. Global coolant will not change the color of the stuff that is already in there. If original red, blue or pink antifreeze is desired, you must get these from a Pentosin supplier or your car dealer.

What color coolant does Toyota use?

Toyota's coolant is pink/orange..not red, not green. The main ingredient in Toyota's coolant is actually ethylene glycol, but with additives and no silicates, best for an aluminum radiator and heads/block. It's OAT, Organic Acid technology.

Is it OK to mix green and blue antifreeze?

Nope. You can mix blue and green. Do not mix any other color with the red coolant (the supposed lifetime crap), if you do the mix will turn into a gel and you'll have one hell of a mess to deal with.

Can you mix different Colour coolants?

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).

Can you mix ethylene and propylene glycol?

Propylene glycol can be mixed with ethylene glycol without causing harm to the cooling system, but it does slightly weaken the heat transfer.

What color is global antifreeze?

Because PEAK Global LifeTime Antifreeze is the first antifreeze specifically formulated for use in all makes and models, the unique amber color will not change the color of your antifreeze when used to top off the cooling system. So if your antifreeze is already green, it will stay green, or orange, or yellow or blue …

What color should engine oil be?

Oil can be very, very dark (black even) and still be effective. However, as a general rule: New, clean oil is amber in color. As engine oil gets darker, it can indicate a) high heat, b) contaminants, or c) the presence of additives that cause the oil to darken during normal use.

Why is my coolant red?

Red coolant is usually GMs thing. If you put red coolant in a ford system then it'll mess things up. It's also possible the coolant is red because of a leak into the radiator from the trans cooler.
