Blue Chem - Radiator Stop Leak Additive 300ml Anti-Leak for Cooling System

Blue Chem Radiator Stop Leak PT33316 is a professional sealing additive for the engine cooling system. Formulated to seal micro-leaks in the radiator, hoses, fittings, and cooling circuit gaskets, it helps stop coolant leaks before they become a costly mechanical problem. 300ml format, applied directly to the radiator with no disassembly required.

Blue Chem Radiator Stop Leak works by forming a flexible, heat-resistant seal at the point of micro-leaks, compatible with all types of coolant on the market. It is particularly useful as a preventive treatment and as a temporary emergency solution on vehicles with a slowly leaking cooling circuit. It does not block radiator channels when used in the stated doses.
