12 Oz. Radiator Stop Lea

The 12 Oz. Radiator Stop Leak from CYCLO is a crucial coolant additive designed to seal minor leaks in your vehicle's cooling system without the need for a complete radiator replacement or flush. This product is particularly beneficial for mechanics and vehicle owners who encounter slow coolant loss due to aging engines, corroded passages, or hairline cracks in hoses.

CYCLO's formulation works by conditioning and thickening the coolant film, allowing the system to self-seal micro-fractures and corrosion pits from within. The 12 fl. oz. concentrate is easily mixed directly into the radiator or coolant reservoir, ensuring it disperses throughout the entire cooling loop, including block passages, heater core, and gasket interfaces. Its chemistry is compatible with both traditional green and extended-life orange/pink coolants, but it's essential to verify your vehicle's coolant type before mixing.

This additive is invaluable for vehicle owners facing coolant seepage, older model enthusiasts running high-mileage engines, and fleet operators managing cooling system maintenance. With a practical shelf life, it can be stored easily in any shop or garage, making it a smart choice for preventive inventory.
