Mishimoto Liquid Chill™ radiator coolant additive is a simple yet effective way to reduce engine temperatures. This additive is compatible with all coolant types and does not require mixing. Mishimoto Liquid Chill™ is proven to reduce engine temperatures and is suitable for use in any liquid-cooled engine, including your diesel pull truck, road course hatchback, or trail riding dirt bike. Mishimoto Liquid Chill™ is safe for use with all alloys and is formulated with a corrosion inhibitor, which not only prevents future corrosion but also will reduce pre-existing buildup. This additive is 100% biodegradable, non-corrosive, and nontoxic, making it a safe and effective solution for reducing high coolant temperatures. The ultra concentrated formula means you need only one small bottle for a car or dirt bike and two small bottles for a larger truck.

As for the Mishimoto Liquid Chill™ Synthetic Engine Coolant: formulated to operate flawlessly under extreme conditions and with both gasoline and diesel, Liquid Chill™ will help your engine warm up quickly and maintain ideal operating temperatures.

Liquid Chill™ Synthetic Engine Coolant technology combines an inherently nontoxic propylene glycol base with unique poly organic additives (POAT) to allow a service life that can exceed 7+ years or 750,000 miles in Heavy Duty (diesel) applications and over 2+ years or 250,000 miles in Light Duty (gasoline) applications, although Mishimoto engineers recommend consulting your service manual for application-specific guidelines. Liquid Chill™ Synthetic Engine Coolant is designed to meet or exceed all stock specifications and exceeds the specs needed to pass ASTM D6210 and ASTM D3306 coolant tests. It's premixed with deionized water, so it's ready to use and safe for all water-cooled engines, protecting against boilover to 265°F and freezing to -26°F (with 15 psi cap)**.

The proprietary formula doesn't contain any nasty nitrates, amines, high-fructose corn syrup, phosphates, silicates, borates, and all those other "ates" that will clog up thermostats and radiators, and cause excessive wear on water pumps. However, Mishimoto engineers strongly recommend that you and your children do NOT consume this coolant. Seriously, don't drink it, and keep it on a high shelf so kids and pets can't get to it.

Mishimoto even made a DIY video on how to bleed your coolant system!
