The Mishimoto Liquid Chill Synthetic Engine Coolant is engineered to provide long-lasting protection and optimal engine performance. Utilizing a proprietary blend of nontoxic propylene glycol base and unique poly organic additives (POAT), this coolant offers an extended service life that can surpass 7 years or 750,000 miles in heavy-duty diesel applications and over 2 years or 250,000 miles in light-duty gasoline engines. It is pre-mixed with deionized water, ensuring ease of use and compatibility with all water-cooled engines. This coolant effectively prevents boilover up to 265°F and resists freezing down to -26°F, even with a 15 psi cap, making it suitable for a wide range of climates and operating conditions. Designed to meet or exceed all stock specifications, Mishimoto's Liquid Chill coolant surpasses ASTM D6210 and ASTM D3306 standards, guaranteeing reliable performance and engine protection. This product is ideal for those seeking a high-quality, long-lasting coolant that reduces engine wear and helps lower operating temperatures, contributing to overall engine longevity and efficiency. The one-gallon size provides ample supply for routine maintenance or multiple applications, ensuring your engine stays protected and running smoothly over time.
