Bar’s Leaks Radiator Stop Leak 2X Concentrate Sealer is an emergency and preventative maintenance product designed to quickly and reliably stop minor to moderate leaks in your vehicle’s cooling system. This 2X concentrated formula is powerful enough to seal leaks up to 0.9 mm in size in key areas like the radiator, heater core, engine cooling jacket, gaskets (including head gaskets), and freeze plugs. By forming a lasting seal, it prevents the loss of crucial coolant and helps avoid costly repairs, giving you time to reach a repair facility or extending the life of an older system. It is also formulated to freely recirculate without clogging the system, offering protection against future leaks.
Key Features of Bar’s Leaks Radiator Stop Leak 2X Concentrate Sealer
Additional Information
To use this stop leak effectively, ensure your engine is warm before adding the product, as the heat helps the formula activate and circulate. It is best to pour the product directly into the radiator opening (not the overflow reservoir, if possible) or the upper radiator hose for fastest circulation. After installation, idle or drive the engine for 15 to 30 minutes to allow the sealant to find and seal the leaks. If your cooling system is dirty or has other stop leak products, consider flushing it with a cleaner like Bar’s Leaks Nural before application for the best results.
