Super-Long-Life OAT Antifreeze/Coolant, -50°C (Cold-Climate)
Product Description
Super-Long-Life OAT Antifreeze/Coolant, -50°C (Cold-Climate). KATMOTO Super Long Life Coolant -50°C is a ready-to-use super-long-life ethylene-glycol OAT coolant formulated for cold climates, delivering freeze protection to -50°C with extended-life corrosion protection for modern engine cooling systems.
Key Performance Features
| -50°C freeze protection
protects the cooling system against freezing down to -50°C as supplied. |
Long-life corrosion protection
organic-acid (OAT) inhibitors protect aluminium, iron, copper, brass and solder. |
| High boiling protection
raises the boiling point to resist summer overheating and boil-over. |
Super-long service life (typically 7 yr / 300,000 km)
extended service life reduces maintenance and coolant changes. |
| Hard-water tolerance
stable performance and scale control across water qualities. |
Foam & deposit control
low-foaming formulation keeps the cooling system clean. |
Applications & Performance Level
| Applications | Cold-climate passenger-car and light-vehicle cooling systems requiring a Super-Long-Life OAT coolant with -50°C freeze protection. |
| Specification | ASTM D3306-style — passenger-car ethylene-glycol coolant performance. OAT super-long-life — extended-life organic-acid inhibitor technology. Cold-climate -50°C — high freeze protection for severe winters. Super-long service — typically up to 7 years / 300,000 km. Aluminium protection — protects modern aluminium engines and radiators. |
| OEM Suitability | Cold-climate passenger cars and light vehicles specifying a super-long-life OAT coolant. Confirm OEM color/spec compatibility before topping up. |
| Important Notice | Freeze protection is as supplied (ready-to-use). ”Suitable for” does not mean official approval unless separately certified. Follow the OEM coolant specification, color compatibility and change interval. |
