There are three main types of coolant that car companies use: Inorganic Additive Technology (IAT), Organic Acid Technology (OAT), and Hybrid Organic Acid Technology (HOAT). Typically, older cars use IAT. It needs to be changed every two years or 24,000 miles, making it far inferior to newer formulas.Sep 4, 2018
Different Coolant Types
Different vehicles require different coolants. There are varieties for every type of vehicle, from diesel engines to American, Asian and European vehicles. Each one is specifically formulated to keep its designated engine type running in extreme temperatures.
There are lots of different types of antifreeze and it’s crucial to understand that there is no single antifreeze that’s suitable for all makes and models. The best thing to do is to always use the antifreeze that’s recommended by your car manufacturer.
Inorganic antifreeze is formulated using Inorganic Acid Technology (IAT), and it contains ethylene glycol.
Your car does not need to be running for you to add the coolant. … You must not remove the radiator cap and add the coolant to the expansion tank under the hood. As long as the engine is not too hot, you can add your coolant. Just ensure the reservoir is warm.
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.
Blue G11 coolant doesn’t mix with G12 or green, orange or any other off the shelf coolants.
While green coolant is often thought of as traditional or conventional and the color orange is associated with the newer long-life products, there are no hard-and-fast color rules when it comes to engine coolants. All will help keep the cooling system from both overheating and freezing.
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.
While the manufacturers of these coolants recommend only using them in an aluminum radiator, as opposed to the copper/brass radiators, we still don’t recommend them in our all-aluminum radiators. … We recommend the traditional yellow/green coolant because it has always worked for us.
It’s perfectly backwards compatible if you want to do that. But you really don’t want to mix them, it’s not that good of an idea to mix them. If you want to have the correct coolant added for you, consider YourMechanic. They will be able to come to your home or office to perform this service.
A. Yes it is possible to differentiate between ethylene glycol and propylene glycol using both refractive index and specific gravity. The key to differentiate the two is to use the physical differences with regard to specific gravity and refractive index.
The year of the first nonstop, solo transatlantic flight, Prestone® also wows the world … with the first nonflammable Ethylene Glycol. Prestone® Ethylene Glycol Antifreeze safely keeps engines from freezing; transforming winter driving from a rarity to a routine.
Even so, universal coolants are formulated to mix with virtually any coolant. The makers of these product say their antifreeze can be safely used in any year, make or model of vehicle.
If you mix up different types of coolants (propylene glycol \ ethylene glycol) you might end up having gel like substance which naturally will fully or partially block coolant flow, causing eventual engine failure (over heating).
Refilling your coolant is a fairly simple car maintenance task you can do yourself, as long as you follow the right steps. Before you start, always make sure your engine is switched off and cool. Your coolant reservoir should be labelled, and they are usually translucent plastic.
Well, antifreeze and engine coolant are similar, but not the same. Antifreeze is a concentrated, glycol-based liquid that must be diluted with water before use – at which point it is referred to as coolant. Alternatively, you can purchase pre-mixed engine coolant, a ready-to-use solution of antifreeze and water.
The answer: nothing good. Coolant circulates through your car and extracts heat from various components, keeping their operating temperature within normal parameters. Without coolant, there’s nothing to extract this heat, and these parts quickly overheat and break down.
Depending on the vehicle and the coolant, the average time between flushes is two years or 30,000 miles for silicated coolants and up to five years or 100,000 miles for an extended drain coolant. You can tell which type of coolant you have by the color.
Hybrid Organic Acid Technology (HOAT)
To differentiate these a little easier, HOAT coolants are found in yellow, turquoise, pink, blue or purple colors.
Fluid Type: | Colour: |
---|---|
Transmission Fluid | Pink, red, or brown |
Power Steering Fluid | Reddish brown |
Brake Fluid | Pale amber |
Coolant/Antifreeze | Bright green or yellow |
Opticool Antifreeze Universal (Clear) is a monoethylene glycol based ready-to-use engine coolant which uses Organic Acid Inhibitor Technology and is free from nitrites, amines, phosphates, borates and silicates (BTC Classification Type 4E).
Yes. Prestone’s Coolant/Antifreeze is guaranteed to be compatible with all cars, vans or light trucks. Thanks to its unique and patented formula, Prestone Coolant/Antifreeze remains the only coolant on the market that can be mixed with another product within the cooling system without causing damage.
Blue Antifreeze: Blue antifreeze has been formulated for use in Infiniti, Nissan, Mazda, and Mitsubishi Vehicles. It’s another long life, anti-corrosion formula meant to last a good five years in your radiator. There are other blue antifreezes that are for use in Acura, Honda, and Subaru vehicles.
Antifreeze mixes with water to form a covalent bond to prevent the water from freezing. … Antifreeze Blue is a full concentrate which meets BS6580 and contains the same pure ethylene glycol and anti-corrosive additives as the Red. Its application is for protection for up to a maximum of 2 years.
Both orange and green antifreeze serve as engine coolants, designed to keep it from freezing or overheating. They also defend the cooling system against corrosion.
