RADIATOR LEAK SEALANT POWDER

Bar's Radiator Leak Sealant Powder will seal minor leaks up to 0.9 mm in size that occur within the cooling system. Bar's Radiator Leak Sealant Powder works in plastic, aluminum, and metal radiators. It also stops leaks in heater cores, small hose clamps, engine blocks, cooling jackets, gaskets (including head gaskets), and freeze plugs.

Instructions:
Pour the contents of the container into the radiator (not into the overflow tank) after the engine has cooled. The contents can also be installed in the upper radiator hose by removing the radiator hose and pouring the contents directly into the hose. Replace the radiator cap (or hose) and run the engine for 15 minutes. Check for leaks. If leaks persist, use a second application. Use one package for 4-cylinder engines and two packages for 6 to 8-cylinder engines. For best results, use Bar's Nural or Bar's 10 Minute Flush to clean the cooling system of dirty radiators.
NOTE: Mechanical attention may be needed if leaks continue after treatment.

Benefits:
Seals leaks throughout the cooling system.

Warnings:
Always exercise caution when working near an engine or radiator. Be careful when removing the radiator cap. DANGER: Opening the cooling system with the engine hot or running can cause severe burns.
