## Description

Product Description

Review: Highly recommend - Highly recommend, writing this review after driving my vehicle more then 6k kms. I had used k seal before this it didn't last even for 1000kms but this product has done the job. I used this product for heating coil leakage of ford figo petrol. After use I have done the journey from kashmir to gujarat and gujarat to assam there was no complaint about any leakage. Thank you GAT.
Review: Best Quality - I used GAT Energ Radiator Sealant in my Hyundai Verna 2017 to seal coolant leaks, and after 5356 km, there are no leaks. Highly recommend this product for its effectiveness and quality.

## Features

- GERMAN AUTOMOTIVE TECHNOLOGY (GAT): Formulated utilizing advanced German Automotive Technology (GAT) guidelines to meet complex cooling system needs. It provides an instant seal for modern closed cooling systems, saving vehicles from sudden, expensive engine block warping
- SEALS HAIRLINE CRACKS & MINOR LEAKS: Explicitly engineered to seal hairline cracks and small leaks instantly. It stops cooling fluid from dripping out of thin radiator cores, heater matrix connections, hose joints, and water pump gaskets, preventing a catastrophic loss of cooling water
- ACTIVE OPERATION REACTION TIME: Features a specialized chemical compound that works during operation. It stays completely liquid inside normal coolant fluid until it meets a pressure drop at a leak site, hardening selectively without clogging narrow cross-flow radiator tubes
- IMPROVES ENGINE OPERATIONAL SAFETY: Significantly improves the operational safety of engines. By stabilizing coolant levels and preventing pressure dropouts, it guarantees consistent heat transfer away from hot cylinder walls, keeping your temperature gauge safe
- ANTI-CORROSION SYSTEM DEFENSE: Protects against engine damage and corrosion throughout the system. This highly concentrated 300ml bottle is sufficient for 12 liters of coolant, providing a universal treatment for passenger cars, trucks, tractors, and marine boats
- QUALITY CERTIFICATION: Manufactured in Germany with TUV approval, ensuring high-quality standards and reliable performance for your vehicle's cooling system requirements
