Bar’s Leaks says it has reformulated its Liquid Aluminum Radiator Stop Leak into a stop leak for the entire cooling system. The company says its Liquid Aluminum Cooling System/Radiator Stop Leak has been formulated specifically to permanently seal the coolant leaks that cause most overheating problems; it now features the company’s proprietary Xtreme Cool wetting agent, which is designed to reduce the surface tension of coolant – which increases its wetting ability – as well as improve heat transfer and reduce coolant temperature.

Bar’s Leaks Liquid Aluminum can be used in cars, trucks, vans, SUVs, buses and RVs – anything with a radiator, according to the company, which says the product is compatible with all types of antifreeze, including conventional green or blue (silicate-based) and extended-life red/orange or yellow (OAT/HOAT) variants. It is added directly to the vehicle’s cooling system, the company says; no flushing is required, and most leaks are sealed instantly.

Bar’s Leaks Liquid Aluminum is available in case packs of six 16.9-ounce bottles; the label includes directions in both English and Spanish. For more information, go to
