5. CRC Evapo-Rust TC001 Best Radiator Flush Product
The Evapo-Rust Thermocure Coolant System is designed to recondition the cooling system of a vehicle or other piece of machinery.
It uses a process called thermolytic degradation to remove rusted and corroded metals from the engine. Unlike many other cooling system flushes, it contains no acids, bases, solvents, or other toxic ingredients.
The product rehydrates water pump seals; thus allowing them to oil and cool internal components better than they did originally.
In addition, it helps restore the combustion process in so far as improving airflow through compromised cylinders by preventing rust from laying on top of the anti-freeze feeding water pumps.
Once rust and corrosion is eliminated from the cooling process, there is much less wear on these parts which reduce overall heat buildup in the engine block resulting in longer-lasting and more efficient equipment.
Evapo-Rust is a rust remover that can be used on thousands of different products in the home, kitchen, and automotive environment.
