Product Description
Long-Life Organic-Acid (OAT) Antifreeze/Coolant, -35°C. KATMOTO Long Life Coolant -35°C is a ready-to-use long-life ethylene-glycol coolant based on organic-acid technology (OAT), providing year-round freeze and boil-over protection and long-life corrosion protection for modern passenger-car cooling systems.
Key Performance Features
| -35°C freeze protection
protects the cooling system against freezing down to -35°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. |
Long service life (typically 5 yr / 250,000 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 | Passenger-car and light-vehicle cooling systems requiring a Long-Life OAT coolant with -35°C freeze protection. |
| Specification | ASTM D3306-style — passenger-car ethylene-glycol coolant performance. OAT / silicate-free — organic-acid long-life inhibitor technology. Mixed-fleet suitable — compatible with most modern aluminium and cast-iron engines. Long-life service — typically up to 5 years / 250,000 km. Boil & freeze protection — year-round cooling-system protection. |
| OEM Suitability | Modern passenger cars and light vehicles specifying a long-life OAT ethylene-glycol 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. |
