![]() Wolf offers G11, G12+ and G13 specified coolants. This keeps the cooling system pure.Ĭan’t flush your cooling system? Check this table to see which types you can safely mix. However, we recommend thoroughly flushing your cooling system when upgrading from a different type of coolant. ![]() How to upgrade to G13 from an older type of antifreezeįor modern radiator types, G13 antifreeze is backward compatible. Use antifreeze with G11 or G12 specification instead. Appearance, visual Color Visual Yellow Ash Content w/w maximum ASTM D1119 2.5 Freeze Point as sold ASTM D1177 -34.6 0F pH as sold ASTM D1287 8.0 - 9.0. It doesn’t work well with the lead solder. Heavy duty diesel or gasoline engine antifreeze. On the other hand, G13 is not the best choice for older cooling systems with copper/brass radiators and heater cores. Silicate additives make G13 ideal for long-term use in all modern radiators, especially those constructed from aluminium, cast iron and magnesium alloys. This is contrary to some earlier specifications that use OAT-technology (Organic Acid Technology). Most electric vehicle applications can use a standard engine coolant, she says. Engine: Capacity: Change interval: Antifreeze type: Grand Cherokee 3. Its not guaranteed that the color means anything about the coolant. Car A Rac presents recommended by manufacturers types for all popular vehicles. Find out how much coolant does your car need. G13 contains some silicate additives for that additional healing aluminium protection. Recommended antifreeze for radiators of Jeep Grand Cherokee. ![]() Silicate additives for use in radiators with aluminium Next to protection against freezing, the G13 is also excellent for cooling and protection against corrosion and chalk deposits. It is estimated that the manufacturing of G13 produces 11 % lower CO2 emissions than antifreeze with glycol. One is a bi-product of biodiesel production, the other is produced from mineral oil. Glycerin is much less harmful to the environment than glycol. The main difference: it is manufactured using glycerin instead of glycol. The G13 has a purple/violet colour and has the same exceptional cooling and antifreeze performance as G12++. Glycerin based, so environmentally friendly Throughout the years their antifreeze specification has evolved, with the latest (G13) established in 2013. Alliance Green CoolantĪlliance Green Coolant is a Conventional low silicate Automotive formula that requires the addition of Supplemental Coolant Additives to be used in Heavy Duty Diesel applications.Let’s take a quick look at the different VW specifications. Alliance Fully Formulated SCA Pre-Charged CoolantĪlliance Fully Formulated SCA Pre-Charged Heavy Duty Diesel Engine Coolant is pre-charged with supplemental coolant additives in a Pink Conventional low silicate, non-phosphate formula that helps prevent inhibitor dropout, scale deposits, and gel problems frequently associated with diesel engine cooling systems for 2 years/25,000 miles. Alliance OAT Extended Life Coolant keeps the cooling system running cooler and components lasting longer while providing complete protection against corrosion, erosion and cavitation for 1,000,000 miles/20,000 hours of cooling system protection. Alliance OAT Extended Life CoolantĪlliance OAT Extended Life Coolant is a NITRITE-FREE, patented, non-silicate, non-phosphate formula that eliminates inhibitor dropout and scale problems. Our coolants provide reliable protection in even the most extreme heat and freezing cold conditions. Alliance Extended Life coolants are different – specifically formulated to not just meet, but to exceed the performance requirements of your
