COOLANT PRO
Powerex COOLANT PRO 1:4 OAT is a premium concentrated engine coolant formulated using Organic Acid Technology for modern automotive and industrial cooling systems. The coolant is designed to be diluted with clean demineralised water in the recommended 1:4 ratio before use.
Built with BS6-Thermo Defense Tech, COOLANT PRO supports efficient heat transfer, corrosion protection and long-term radiator cleanliness. Its OAT-based inhibitor system helps protect cooling system components during regular engine operation and supports stable coolant performance over service life.
COOLANT PRO is suitable for vehicle owners, workshops, fleet users and maintenance teams looking for a dependable OAT coolant concentrate for BS-6 vehicles, modern engines, radiator systems and cooling circuits where OAT-based coolant is recommended.
- Suitable for radiator and engine cooling systems requiring OAT-based concentrated coolant.
- Designed to be diluted in 1 part coolant concentrate with 4 parts clean demineralised water before filling.
- Suitable for selected BS-6 vehicles, passenger cars, commercial vehicles, two-wheelers, tractors, generators and industrial cooling systems where OAT coolant is recommended by the vehicle or equipment manufacturer.
- Can be used in modern cooling systems requiring efficient heat transfer, corrosion protection and long-term coolant stability.
- Suitable for workshops and fleet maintenance teams handling OAT coolant replacement and radiator service requirements.
- Do not use undiluted. Do not mix with IAT, HOAT or unknown coolant chemistry unless compatibility is confirmed by the vehicle or equipment manufacturer.
-
Organic Inhibitor Protection — BS6-Thermo Defense Tech provides OAT organic acid technology inhibitor protection for long-term cooling system care.
-
Metal Surface Corrosion Reduction — Reduces corrosion on aluminium, cast iron, copper and brass throughout extended coolant service life.
-
Long-Term Coolant Stability — Maintains coolant stability and inhibitor effectiveness over extended service intervals.
-
Radiator Cleanliness — Assists long-term radiator and cooling system cleanliness, preventing scale and deposit formation.
-
OAT Long Life Coolant — OAT (Organic Acid Technology) — the long-life coolant grade for BS-6 and modern engines.
