PEAK Sierra Antifreeze\/Coolant (1 gallon) is aimed at vehicle owners and professional shops seeking a less toxic, propylene-glycol based coolant for everyday passenger cars, light trucks, and equipment that specify or accept propylene-glycol formulas. It’s a practical option for drivers who want a ready-to-use container for topping off or for technicians who need a single-gallon supply for service jobs. Always confirm your vehicle’s coolant requirements and follow disposal regulations for used fluids.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is PEAK Sierra Antifreeze safe for pets compared to ethylene-glycol antifreeze?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: PEAK Sierra uses propylene glycol, which is less toxic than ethylene glycol, but it is still hazardous—keep it away from pets and children.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Do I need to dilute this gallon before adding to my radiator?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Check your vehicle manual; some radiators need pre-diluted coolant while others require mixing with distilled water to the recommended ratio.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"PEAK","offers":[{"title":"Default Title","offer_id":48082935513246,"sku":"B000CCM5JA","price":53.42,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/peak-sierra-front-packaging.jpg?v=1785819396","url":"https:\/\/northtrailauto.ca\/products\/peak-sierra-antifreeze-coolant-1-gal-propylene-glycol-lower-toxicity-heat-protection","provider":"North Trail Auto","version":"1.0","type":"link"}
