What are the different types of coolant?
Finding the Right Fluid 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.
What are the different types of antifreeze or 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 |
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 is the best antifreeze coolant?
- Valvoline MaxLife Engine Antifreeze : Best Multi-purpose Antifreeze.
- Shell Rotella ELC Nitrite Free Antifreeze : Best Antifreeze for Diesel Engines.
- EVANS Cooling Systems High-Performance Waterless Engine Coolant : Best High-Performance Coolant.
- Havoline Xtended Life Engine Coolant : Best Ready-To-Use Coolant.
Is anti-freeze and coolant the same thing?
Antifreeze and coolant are not the same thing because the antifreeze is an undiluted chemical additive that has the ability to reduce the freezing point and increase the boiling point of water-based liquids whereas the coolant is a by-product of water and antifreeze most commonly mixed at a 50:50 ratio.
What type of antifreeze should I use?
A 50/50 mix antifreeze, green coolant, would be your best bet. Anything that says “safe for older automobiles” would also work. Be careful of “Extended-Life” additives, as these will eat away at older aluminum, and could cause more harm than good.
What type of engine coolant/ant-freeze to use?
The BWM coolant antifreeze is essential for keeping your engine temperatures in check. It lubricates the car’s water pump, thus protecting it from corrosion. In winter months, this coolant helps to antifreeze your engine. Also, it helps in cooling the transmission oil coolers. This coolant has a blue color.
What are the different types of antifreeze?
There are 3 basic types of antifreeze used today, ethylene glycol based, propylene Glycol based and the newer Organic Acid Technology. The biggest thing to look out for is using the organic acid technology (OAT) in older vehicles with brass or copper radiators.
