Prestone® Antifreeze+Coolant prevents corrosion and keeps your radiator performing optimally. Buildup in the engine block cooling channels can make it difficult for coolant to travel. This can cause excessive heat, resulting in oil becoming too hot and thin and potentially damaging the whole system.

Usually (but not always) dyed orange or yellow so you could tell the difference between OAT and IAT, this coolant has similar corrosion protection as the green stuff, however they are designed to be slower acting, hence the extended-life moniker.

Green and orange-colored antifreeze are usually used in older vehicles. It's compatible with all types of metal, including aluminum. Yellow-colored Antifreeze is used in European cars. It's not compatible with aluminum and should only be used in engines that have copper radiators.

Organic acid technology (OAT) OAT engine coolant is made with a propylene glycol base. Organic acid technology (OAT) engine coolant is usually orange in color, but it can come in other colors like dark green. Always double-check the label to ensure you do not accidentally grab a color that is a different coolant type.

The main difference between IAT and OAT is how they protect against corrosion. IAT creates a barrier between metal surfaces, while OAT changes the pH of the coolant to make it more acidic. This acidity helps prevent corrosion from occurring in the first place. OAT coolants also have a longer lifespan than IAT coolants.
