Need a rust remover for a cooling system? Thermocure claims to be safe, simple and easy to use. Thermocure restores the engine’s ability to transfer heat to the coolant, which allows the engines to run cooler and last longer. Thermocure works great in automobiles, ATVs, diesels, RVs and tractors.
Thermocure is designed to remove rust scale and deposits from radiators, water pumps, water jackets, engine blocks and heads. The procedure is simple. Once the cooling system is completely drained and coolant is removed from the radiator, add a mixture of Thermocure and water to the radiator. The vehicle should be run for three to four hours up to three days, depending on the amount of rust. The cooling system is then drained and flushed twice with water. Add a high-quality antifreeze after the system is flushed to prevent future problems. Available at Walmart.
