P-HOAT (Phosphated HOAT) Phosphates & Organic Acids PINK

Is OAT coolant better?

OAT coolants last longer than IAT coolants, but they don’t do as good a job limiting corrosion within the cooling system. HOAT coolant offers the best of both worlds: The corrosion resistance of IAT coolant. The long life of OAT.

Is all OAT antifreeze the same?

Present in newer cars all over the world, OAT coolant color ranges from pink, orange, bright red, red, blue and dark green. Organic Additive Technology as it is referred to in some owner’s manuals, is the same as Organic Acid Technology, unless your owner’s manual says differently.

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.

Who uses OAT coolant?

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.

Is Prestone an oat antifreeze?
