Antifreeze and coolant fluids regulate engine operating temperature, protect against freezing and boiling, and inhibit corrosion within cooling systems. Gem Oils supplies a range of antifreeze and coolant products alongside heat transfer fluids for industrial process applications.
Modern engines and industrial systems often use coolants with specific corrosion-inhibitor technologies, such as OAT (organic acid technology) or HOAT (hybrid organic acid technology), which are not always compatible with one another. Using the correct, manufacturer-specified coolant helps protect against corrosion, scale and seal degradation.
Regulates engine temperature and inhibits corrosion within cooling systems
Formulated to recognised OAT and HOAT coolant specifications.
Built for automotive, commercial and industrial cooling systems.
Our technical team will confirm the right coolant for your system before you order.
Always check the required product type, grade, specification and compatibility against the vehicle or equipment manufacturer’s recommendations before use.
Answers to the questions we are most commonly asked by garages, fleet operators, and motor factors. For vehicle-specific advice, contact our technical team directly.
Antifreeze serves two functions beyond frost protection: it raises the boiling point of the coolant mixture, providing protection against overheating in summer, and it contains corrosion inhibitors that protect the metal surfaces of the cooling system throughout the year. Using plain water without antifreeze leaves the cooling system at risk of corrosion regardless of season.
No. Antifreeze products use different corrosion-inhibitor technologies — OAT (organic acid technology) and HOAT (hybrid organic acid technology) are common examples — and mixing incompatible types can reduce corrosion protection and, in some cases, cause deposits to form. Always use the type specified by the vehicle or equipment manufacturer and do not mix with a different type.
Change intervals vary by product type and manufacturer specification. OAT-based coolants typically have longer service lives than older technology products. Always follow the interval set out in your vehicle or equipment handbook. Coolant condition can also be tested with an antifreeze tester or refractometer.
