Sierra Coolant Prop Glycol Green

PEAK® is the pioneer and market leader in the safer propylene glycol (PG) antifreeze category. SIERRA® Antifreeze/Coolant is formulated with PG rather than ethylene glycol – the base for traditional antifreeze. Because of its PG formula, SIERRA® Antifreeze is less toxic and therefore safer for people, pets, and wildlife than conventional antifreeze. It is a premium automotive coolant that provides excellent freeze-up and boil-over protection and outstanding corrosion protection.
