Rebuilding a water cooling system can be a tedious process. All the film left from your previous coolant built up inside. We created a perfect cleaning kit for rebuilding existing systems.

Use the rad clean to make sure any bits and residue is flushed out of your radiator while essentially scrubbing the inside of any chemicals or film.

Next the System Reboot is used to clean the entire loop of any chemical or dye remnants left from your previous coolant. The Reboot will pull any dye off internal surfaces ensuring none bleeds into your next coolant choice.

Finally use the unique PrimoPrep to get your loop prepped for possible PH imbalances caused mostly by high levels of copper mostly from large capacity radiators. With this treatment it also prepares the system for use of coolants in a mix metal closed loop environment leaving the guesswork a thing of the past.
