Antifreeze & Coolant

AMSOIL Propylene Glycol Antifreeze & Coolant (ANT) is formulated to provide benefits beyond those provided by today's conventional antifreeze and coolant products. Unlike conventional ethylene glycol-based products, which are acutely toxic, AMSOIL Propylene Glycol Antifreeze & Coolant is biodegradable and its low toxicity limits the threat to children and animals. Its unique formulation provides maximum cooling system protection in extreme temperatures and operating conditions.

Formulated with proprietary tiered surfactant technology, providing quick and effective heat transfer inside radiator and cylinder heads, which results in reduced operating temperatures, more efficient operation, increased horsepower and significantly reduced engine warm-up times in cold weather.

Available in packs of 6 or 70. Use PACKAGE SIZE drop down to select quantity. AMSOIL antifreeze test strips have two different pads on them and test ALL coolant colors. The lowest reports the freezing and boiling (under pressure) protection level. The upper pad reports the pH level and shows a pass/fail area. No other testing is recommended or required. The test strips are the only way a mixture of ethylene glycol and propylene glycol can be checked for freeze protection.
