Best Radiator Coolant for Cars in India – 1:3 Antifreeze for Bikes & Heavy Vehicles
High Concentrate Coolant | Anti Freeze & Anti Boil | Heavy Duty Cooling | Made in India
BHARAT Concentrate Coolant 1:3 is a high-strength radiator coolant and antifreeze designed for engines that operate under extreme temperature and heavy load conditions. Its advanced formula provides superior heat transfer, corrosion protection, and consistent engine cooling performance.
This concentrated coolant must be diluted in a 1:3 ratio (1 part coolant : 3 parts water), making it stronger than standard coolant formulations. It is ideal for high-performance cars, heavy vehicles, tractors, and industrial engines where powerful cooling and long-lasting protection are required.
