<b> PROFESSIONAL QUALITY RESULTS </b> - With this system, you re-circulate the solvent of choice through the entire cooling system. Depending on the solvent, you can clean out lime, rust, scale, debris and corrosion and keep circulating for hours until crystal clean. Then when completely done, flush the entire system with clean water for crystal clean cooling system flush.
<b> SIMPLE TO USE </b> - There is plenty of hose, and plenty of length, for just about every application. Simply unhook your radiator hoses from your water pump (or the radiator itself) or from the heater core, and partially fill a 5 gal bucket with your solvent solution, drop in the pump and the return line, and connect the pump wires to the battery. Then let the system recirculate for as long as necessary. Then dispose of solvent, and final flush with water to clean the pump and internals
