CarGo FUEL INJECTOR CLEANER is made from 100% powerful cleaners designed to clean gasoline injectors in one application.

CarGo copper reinforced "Liquid Glass" METALLIC SEAL-UP is the only permanent block, head, and radiator sealer that uses expensive copper in the formula. The copper strengthens the bond and transfers heat across the hole or crack to eliminate hot spots. SEAL-UP is ideal for gasoline and diesel engines. A SEAL-UP seal will withstand temperatures up to 2000ºF and 3000 pounds per square inch pressure. A SEAL-UP ceramic-metallic seal is as permanent as a "hot weld" and will last the life of the engine or radiator. One bottle of CarGo # 1008  treats up to a  6 gallon cooling system.
