Test Course

Cool-Rite I™ Radiator Cleaner gently softens and
loosens scale and rust, and holds it in suspension in
the coolant. Then the rust and scale particles drain out
with the coolant. It’s gentle formula doesn’t require a
neutralizer; just drain and refill, and the system’s good
as new. Add a bottle of Cool-Rite II™ Cooling System
Treatment to provide extra lubrication and protection.
