One of the new types is “organic acid technology,” or OAT. It’s orange. General Motors pioneered this chemistry starting with 1996 models in the U.S. and using the name Dex-Cool.Jun 1, 2002
|IAT (Inorganic Additive Technology)||Silicates||GREEN|

Watch for signs of oil or rust.
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.
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.
Peak Dexcool Concentrate Orange Antifreeze is made for use in GM cars and trucks requiring a Dex-Cool antifreeze. It is an orange colored ethylene glycol based antifreeze compatible for use in all automobiles, light duty trucks and motorcycles.
Prestone is yellow, but many other coolant manufacturers use different colours. “These days, there’s no real reason for a coolant manufacturer to use a certain colour, so it’s not easy for you to know what chemicals are in the coolant just by seeing whether it’s blue, green, yellow or orange.Jun 1, 2020
They are traditionally green or orange. Antifreeze is a pure substance that does need to be mixed with equal parts water to make an acceptable engine coolant.
Technically, you can mix coolant types, but before you go ahead and do it, let’s cover some things. … Currently, many coolant producers make solutions that aren’t Dex-Cool but are safe to mix with Dex-Cool. Make sure to read your manual and the label on the coolant that you would like to add thoroughly.
The two coolants should never be mixed together as they do not react well. When mixed together they can form a thick, jelly-like substance that can completely stop all coolant flow which can lead to overheating.
Cars made after 1998 normally need antifreeze that uses silicate-free, organic acid technology (OAT). These types of antifreeze offer better corrosion protection so that parts don’t need to be changed as often. Cars made before 1998 usually need antifreeze that isn’t OAT-based and that does contain silicate.
Yes it does, I have a new Ford Escape and the coolant was pink colored from the Ford dealer.
There is green antifreeze and orange antifreeze. … These days you can actually get yellow antifreeze, blue antifreeze, pink antifreeze and more. The fact is, mixing these liquids is not safe.
|Transmission Fluid||Pink, red, or brown|
|Power Steering Fluid||Reddish brown|
|Brake Fluid||Pale amber|
|Coolant/Antifreeze||Bright green or yellow|
Can you mix red and orange antifreeze? There is no difference between red and green antifreeze. It is ORANGE antifreeze that used to be a concern. It is now safe to mix the colors.
Variations of coolant/antifreeze can come in; pink, red, orange, blue, green, and yellow. 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.
Concentrate. Designed to work with all GM ® vehicles 1995 & newer (GM ®-approved), most Ford ® vehicles 2011-2018 and most Chrysler ® vehicles 2013 & newer.
The universal coolants (Peak Global, Prestone All Makes/Models) can be mixed with Dexcool as well as conventional coolants.

Dex-Cool is now used in almost 40 million vehicles sold by GM since 1996. … On its website, the company now also warns owners to consult their vehicle “owner’s manual for the type of coolant right for your vehicle” and never “mix one type of coolant with the other.”
GM still uses Dex-Cool coolant and there is no longer a problem with gasket coolant interaction. So contrary to the ranting, DexCool IS the recommended coolant for GM engine.
Back in 1995, GM began to use “Dex-Cool” coolant in its vehicles; in fact, you may very well be driving a vehicle that uses Dex-Cool.
The old technology, a.k.a. “conventional,” a.k.a. “inorganic,” is green in color. Most of what you see on the shelves at Wal-Mart and AutoZone is conventional, including the yellow bottles of Prestone and the white bottles of Zerex. One of the new types is “organic acid technology,” or OAT. It’s orange.
Inorganic antifreeze is formulated using Inorganic Acid Technology (IAT), and it contains ethylene glycol.
Water by itself can’t do the job of antifreeze due to its lack of boiling and freezing point range and its inability to protect your vehicle’s engine. Plus, it doesn’t absorb heat as effectively. In the case of an absolute emergency, you can use water in your coolant rank.
If you mix two different coolants together, it will create a think substance that resembles that of a jelly. If this happens, the coolant will not be able to do its intended job. Instead, it will cause the engine to overheat. The damage can reach gasket, water pump, and radiator.
Prestone Prime Antifreeze/Coolant offers superior long-lasting performance over many other brands. Cars and light-duty trucks using this formula are protected against engine overheating for 150,000 miles or 5 years. Prestone Prime is also useful for heavy-duty vehicles, such as RVs and tractor trailers.
Well, you use the coolant that is specified in your owner’s manual. If you just need to top it up, the recommendation is still the same, however it is unlikely to cause any serious problems if you add a litre of a different type of coolant, as long as you follow the manufacturer’s maintenance schedule.
