The Mishimoto Liquid Chill Synthetic Engine Coolant is a high-performance, ready-to-use coolant designed for both heavy-duty diesel and light-duty gasoline engines. It features a proprietary poly organic additive technology combined with a nontoxic propylene glycol base, ensuring a service life that can surpass 7 years or 750,000 miles in diesel applications and over 2 years or 250,000 miles in gasoline engines. This extended lifespan reduces maintenance frequency and provides reliable engine protection over long periods. The coolant is premixed with deionized water, making it convenient for immediate use without additional mixing. It effectively safeguards engines against extreme temperatures, maintaining operational stability by preventing boilover at temperatures up to 265°F and freezing at as low as -26°F, even under a 15 psi cap. This broad temperature range ensures your engine remains protected in diverse driving conditions. The formulation exceeds ASTM D6210 and ASTM D3306 standards, confirming its compatibility with stock cooling system specifications and its ability to withstand rigorous testing. Mishimoto’s coolant is engineered to meet or surpass all factory requirements, providing peace of mind for vehicle owners seeking dependable engine cooling. Suitable for all water-cooled engines, it helps reduce engine wear and lowers operating temperatures, contributing to overall engine longevity and performance. This product is a universal fit for various vehicle types and is designed to deliver long-lasting, effective cooling performance with minimal maintenance. Its compliance with Prop 65 further ensures safety and environmental responsibility. Whether for routine replacement or upgrading your cooling system, Mishimoto’s Liquid Chill Synthetic Engine Coolant offers a reliable, high-quality solution for maintaining optimal engine health and performance.
