Bar's Leaks Radiator Stop Leak
w/ Water Pump Lube
Bar’s Leaks Radiator Stop Leak w/ Water Pump Lube is formulated as a complete cooling system tune up, used for both emergency stop leak and cooling system maintenance.
It works on plastic, aluminum, and metal radiators in heater cores, engine cooling jacket, gaskets (including head gaskets), water pumps, and freeze plugs. Bar's Leaks Rhizex helps reduce cavitation by breaking-up ultra-low pressure cavities and reduces the internal micro-implosions that cause damage to water pump impellers. Special Buffing agents help keep the cooling system clear and clean and the added anti-rust lubricant will help quiet noisy water pumps while protecting and increasing the life of the entire cooling system.
Keep Bar's Leaks Radiator Stop Leak in your emergency repair kit for those unexpected surprises and apply once a year to keep your cooling system working at its best.
Use Bar's Leaks Flush prior to application to ensure your cooling system is clean.
