Hybrid organic acid technology (HOAT) combines IAT and OAT with nitrites. Zerex uses ethylene glycol for freeze and boilover protection, and a hybrid organic acid corrosion inhibitor package to protect engines from liner pitting and corrosion, and protects all system metals including aluminum.
How long does IAT coolant last?
IAT antifreeze has a 2 year or 30,000 mile service life, where OAT and HOAT have a 5 year or 150,000 mile service life.
What’s the difference between Hoat and OAT coolant?
1. The Story on HOAT. Inorganic Acid Technology (IAT) Coolant was pretty much the original type of coolant and is still used in older vehicles. Organic Acid Technology (OAT) Coolant uses additives to increase its lifespan significantly — up to around 150,000 miles.
Is Dex cool OAT or Hoat?
Dex-Cool® is an OAT, an ethylene glycol based antifreeze that is nitrite-, borate-, phosphate-, nitrate-, amine-, and silicate-free with the same metal wear protection as an IAT antifreeze. Dex-Cool® is trademarked by GM. HOAT (Hybrid Organic Acid Technology) Mixture of OAT and IAT antifreeze.
Can I use OAT coolant in my car?
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.
What color is OAT coolant?
ORANGE
The Colors of Coolant
| TYPE | INHIBITOR TECHNOLOGY | COLOR |
|---|---|---|
| OAT (Organic Acid Technology) | Organic Acids | ORANGE |
| HOAT (Hybrid OAT) | Silicates & Organic Acids | YELLOW |
| HOAT (Hybrid OAT, Phosphate-free) | NAP Free | TURQUOISE |
| P-HOAT (Phosphated HOAT) | Phosphates & Organic Acids | PINK / BLUE |
Is Prestone Hoat or OAT?
Prestone is an OAT coolant/antifreeze but also contains anti-corrosion ingredients to protect your cooling system.
What happens if you mix Hoat and oat?
This type of coolant mixes technology from the first two to create a low-silicate, nitrite technology. HOAT coolants formulations are not compatible with OAT coolants because they do contain nitrites. They should not be mixed together.
What happens if you mix Hoat and OAT coolant?
Mixing IAT with OAT, HOAT or NOAT antifreezes will not damage your vehicle’s cooling system; however the mixture will negate the long life/extended life attributes of these formulations. In conclusion, there are a variety of colors available, including oranges, reds, greens, yellows, blues, clear and pink dye colors.
Does GM still use DexCool?
Dex-Cool is now used in almost 40 million vehicles sold by GM since 1996. On its website, GM claims Dex-Cool will last 5 years or 150,000 miles but a steady stream of consumers insist the product is defective and has damaged their vehicles.
Can I use DexCool in my Toyota?
NO IT’S NOT! Toyota Red doesn’t contain silicon or silcates, whereas regular green does. Don’t use Dexcool, or if you do, flush it like it was normal antifreeze, as it will get muddy after extended use.
What is G12 coolant?
This coolant/antifreeze is phosphate free and also silicate free. When supplied by Volkswagen , this coolant/antifreeze is known as G12. Advantages ofG12 over earlier types include improvements in corrosion protection, thermal stability, heat transfer/control, hard water tolerance. lubrication and environmental protection.
What color is fl22 coolant?
NOTE: In the case of older models, the coolant replacement interval is every five (5) years or 60,000 miles. FL22 coolant is compatible with current (Green) ethylene glycol coolant. If FL22 coolant is mixed with existing Orange coolant, coolant color will turn black.
What color is Mopar antifreeze?
If it’s green, it has had regular antifreeze put in it at some point, if it originally came with G-05, which is the HOAT coolant that Chrysler uses. Mopar’s G-05 is dyed an orange color that is almost the same as Dexcool, but this coolant is NOT compatible with Dexcool.
