The Bar's Leaks Cooling System Radiator Stop Leak (16.9 oz.) excels at sealing external radiator and hose leaks. It's ideal for minor cracks and pinholes, quickly stopping drips and pressure loss. Drivers praise its fast action, often noticing results after a short drive.

Choose the Radiator Stop Leak for targeted external fixes, or the Liquid Copper for all-in-one internal and external sealing. Both integrate effortlessly into routine maintenance.
