System Reboot: reconditioning a loop that already ran coolant
System Reboot runs the same conditioning chemistry as SysPrep, but on a loop that has already run coolant — after a fluid swap, after an opaque fluid has clouded, or as part of an annual service. It lifts residue and pulls dye staining out of blocks and tubing without attacking nickel plating, then gets the loop ready for a fresh fill.
PrimoChill is not liable for hardware damage incurred during the cleaning process; use at your own risk.
Drain the old coolant completely
Power down, open the lowest drain point, and let gravity empty the loop fully. Catch it in a clear bucket and look at what comes out — it tells you what the last fill actually did.
Old coolant left in a low spot contaminates the Reboot solution before it even starts working.
