What is antifreeze protection?
Antifreeze, any substance that lowers the freezing point of water, protecting a system from the ill effects of ice formation. Antifreezes, such as ethylene glycol or propylene glycol, commonly added to water in automobile cooling systems prevent damage to radiators.
What is the antifreeze protection level?
A normal 50:50 mix of propylene glycol provides a protection level that will allow an engine to operate at -26°F (-32°C). That means that no ice crystals will form in the coolant till the temperature drops below -26°F (-32°C). This is referred to as the freezing point of the anti-freeze.
What are different types of antifreeze coolant )?
The Colors of Coolant
| TYPE | INHIBITOR TECHNOLOGY | COLOR |
|---|---|---|
| IAT (Inorganic Additive Technology) | Silicates | GREEN |
| OAT (Organic Acid Technology) | Organic Acids | ORANGE |
| HOAT (Hybrid OAT) | Silicates & Organic Acids | YELLOW |
| HOAT (Hybrid OAT, Phosphate-free) | NAP Free | TURQUOISE |
Can coolant freeze while driving?
There comes a point, however, where even antifreeze can’t protect from a freeze. At -36 degrees Fahrenheit (that’s -38 degrees Celsius), antifreeze and coolant will start to solidify, making it very difficult for your engine to turn over.
What are the three types of antifreeze?
Today, automotive service providers use three basic types of engine coolant:
- • IAT – Inorganic Additive Technology.
- • OAT – Organic Acid Technology.
- • HOAT – Hybrid Organic Acid Technology.
- • Hybrid and Electric Vehicle Cooling Systems.
What kind of coolant is used for antifreeze?
IAT Coolant. The most common variety of liquid antifreeze is an IAT formula, or Inorganic Additive Technology. ZEREX™ Original Green is an IAT coolant that has been used for decades and is a formula proven to provide unsurpassed corrosion protection.
Are there any anti freezes that are glycol based?
There are standard anti-freezes that are red and cars that have Dexcool® will be labeled as such. Another myth is that Dexcool® is not glycol based. Not true, all anti-freezes are glycol based, including Dexcool®.
What’s the difference between IAT and Zerex Antifreeze?
It’s important to know the differences so you get the correct antifreeze for your vehicle. The most common variety of liquid antifreeze is an IAT formula, or Inorganic Additive Technology. ZEREX™ Original Green is an IAT coolant that has been used for decades and is a formula proven to provide unsurpassed corrosion protection.
What’s the difference between red and green coolant?
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.
Which is best antifreeze or coolant to use?
Antifreeze/Coolant Compatibility Reference Sheet Hybrid Organic Acid Technology (HOAT) G-05 is a HOAT AFC Light-duty/Medium-duty HOAT Antifreeze/Coolants Color: Yellow, Blue, Green, Pink other colors could be used. Check formulation before making decisions on mixing/top-off or converting to other Antifreeze/Coolants.
Are there any antifreeze that are compatible with Prestone coolant?
Compatible Prestone® Product(s): Mixing/Top-off with Prestone® Dex-Cool® Extended Life Antifreeze/Coolant AF888/AF850 (General Motors, Ford & Navistar approved), Prestone ® Extended Life Antifreeze/Coolant with COR-GUARD AF2000/AF2100, or PRIME by Prestone AF3400/ AF3500 or AF3000/AF3100.
When to use IAT or other antifreeze / coolant?
Conventional (IAT) Antifreeze/Coolants Only use Conventional (IAT) AFC when mixing/top-off. Light-duty/Medium-duty Conventional Antifreeze/Coolants Color: Green, Yellow, other colors could be used. Check formulation before making decisions on mixing/top-off or converting to other Antifreeze/Coolants.
Why do you put antifreeze in your car?
Antifreeze is a glycol-based concentrated liquid that you mix with water and use to fill up your car’s cooling system. As the name suggests, antifreeze prevents your engine’s coolant from freezing in sub-zero temperatures.
