Tectaloy Unlmtd Ready-to-Use Pre-Mix Coolant Green is an Organic Acid Technology (OAT) radiator coolant, perfect for high-performance, multi-valve engines where an extra load is placed on the engine — such as a four wheel drive that tows heavy trailers or caravans. The unique formula of Tectaloy Unlmtd allows for superior cooling-system protection, when demanded.

When used as directed, Tectaloy Unlmtd Ready to Use Pre-Mix lasts for ten years or 1,000,000kms and delivers 100% corrosion protection. This long lifespan is thanks to the low chemical depletion rate of OAT coolants. It is very important to choose a coolant with a quality corrosion inhibitor, especially if you have a new or modern car, in order to prevent the many types of corrosion that can occur within your cooling system. You can trust Tectaloy on this front, with the unique Tectaloy coolant inhibitor package delivering maximum protection against corrosion.

As a type A coolant, Tectaloy Unlmtd Green Coolant offers anti-freeze anti-boil protection and falls into the coolant category that the majority of new car manufacturers will recommend. It is also available in a concentrate, and in Red or Blue to suit your OEM requirements. This listing is for the 5L bottle, but it can also be purchased in 1L and 20L bottles.
