Engine coolant for everyday vehicles

Prestone AF3200 is a green ethylene-glycol antifreeze formulated to the IAT specification. The concentrated formula comes in a one-gallon bottle and meets ASTM D3306 and ASTM D4985 standards. It is intended for drivers who need a basic, phosphate-free coolant for routine top-offs or complete system refills.

Replaces older green IAT fluids

This product upgrades systems still running conventional silicate-containing coolant that has passed its two-year or twenty-five-thousand-mile service interval. The change is worth it when the old fluid shows rust, scale or a freezing point above minus thirty-six degrees Fahrenheit. It is not for engines that require OAT, HOAT or nitrited formulations specified by the manufacturer.

Limited by IAT chemistry and concentration

The inorganic additive package depletes faster than organic-acid types, so the rated life is two years or twenty-five thousand miles regardless of driving conditions. Silicate content can accelerate water-pump seal wear in some modern designs. Concentrated form requires a clean water source and accurate mixing to reach the listed boiling point of three hundred forty-eight degrees Fahrenheit.
