Features

VERSATILE APPLICATION FOR PETROL, DIESEL, AND LPG ENGINES Ideal for all "water" cooled systems, this sealant is suitable for a wide range of engine types, including petrol, diesel, and LPG. It is recommended not only for repairing minor leaks but also as a preventive solution to avoid potential issues before they escalate into costly repairs. By reinforcing the integrity of the cooling system, this product helps maintain vehicle reliability and performance under various driving conditions. Whether used for routine maintenance or emergency repairs, it offers an effective and lasting solution for cooling system leaks.
PREVENTS CLOGGING AND ENSURES TEMPERATURE SENSOR ACCURACY Unlike some sealing products that can lead to buildup and reduced efficiency, this formulation is designed to avoid clogging radiator waterways and temperature sensors. By maintaining proper coolant flow and accurate temperature readings, this product ensures that the engine operates within the ideal temperature range, preventing overheating or inefficiencies. Its compatibility with various antifreeze and coolant types makes it a versatile and reliable choice for ongoing maintenance and preventive care.
ENHANCED PROTECTION AGAINST CORROSION AND RUST Offering more than just leak prevention, this product also provides enhanced protection against corrosion and rust. Exposure to heat, moisture, and coolant chemicals can lead to internal corrosion, weakening the system and leading to expensive repairs. This advanced formulation actively protects metal components from rust and corrosion, helping to maintain engine efficiency and prolong the lifespan of the cooling system. Its compatibility with OAT (organic acid technology) fluids and all standard antifreeze products ensures easy integration into any system.
