![]() Wolf offers G11, G12+ and G13 specified coolants. Avondale Road Pontrhydyrun Cwmbran NP44 1TT Reg No: 307627. This keeps the cooling system pure.Ĭanât flush your cooling system? Check this table to see which types you can safely mix. G12 Coolant ready mixed 1 litre bottle Was: 58.00 Now: 45.95 Contact Us. 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. It doesnât work well with the lead solder. 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). ![]() G13 contains some silicate additives for that additional healing aluminium protection. Silicate additives for use in radiators with aluminium G13 is Glycerine based and comes as a concentrate you dilute with distilled water (also discontinued I think). Next to protection against freezing, the G13 is also excellent for cooling and protection against corrosion and chalk deposits. All G12 products are Glycol based which is bad for the environment. It is estimated that the manufacturing of G13 produces 11 % lower CO2 emissions than antifreeze with glycol. BENDIX antifreeze, designed for use as a refrigerant in all modern engine cooling systems of motor vehicles and. 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. Is identifiable by discoloration (brown, purple,Ä®tc.).Letâs take a quick look at the different VW specifications. Contamination of G12 with other colored coolants.G12 (Red Coolant) must NEVER be mixed withĪNY other coolant.For coolant system drainingĪnd refilling procedures, see 19 Engine-Cooling System. The cooling system has been filled at theįactory with a permanent coolant. lubrication and environmental protection.Äoes not require replacing the coolant as part of In corrosion protection, thermal stability, heat transfer/control, When supplied by Volkswagen,Īdvantages ofG12 over earlier types include improvements This coolant/antifreeze is phosphate freeĪnd also silicate free. Genuine G12 ready mixed coolant additive has been specifically formulated for KODA, SEAT, VW & Audi engines and is designed to provide protection against. flushing is not part of Volkswagen's GLACIER ANTIFREEZE G12+ is a long life silicate-, amine-, nitrite- and phosphates free antifreeze based on Organic Acid Technology (OAT) technology in. ![]() i thought id post this from the mk4 bentley repair manual to give everyone insight on this.Ĭooling system maintenance consists of maintainingĬoolant level, checking coolant freezing point, and inspecting Nearly all global AUTO Manufactures (CARS ONLY NOT HEAVY DUTY APPLICATIONS) have gone to a single coolant For World-Wide production and these OEM coolants are all OAT based and nitrite and Amine free. Since this question has been being asked time and time again lately. G-12 is an OAT (organic acid Technology antifreeze) Just as all the Global type antifreeze and is compatible with the same.
