IF IT LEAKS...
     LET'S FIX IT

Missouri Mule Radiator Stop Leak is a dry powder stop leak that works with anti-freeze to repair leaky radiators fast! No metal filings to ruin water pump seals.

Block Fixer Block Seal is designed to seal cracked ports, cylinder heads and walls, and water jackets.

Block Fixer is able to withstand compression, fire of combustion, and will expand and contract with temperature changes, resulting in a permanent seal. DO NOT use with anti-freeze/coolant.
