Bar’s Leaks has released a product that is said to stop larger cooling system, heater core, and intake manifold leaks.
Bar’s Leaks Liquid Copper is designed stop major cooling system leaks, repair heater core leaks, repair cracked cylinder heads, blown head gaskets, and seals freeze plug and block leaks, the company said.
“For customers who can’t afford a mechanical repair or just don’t think their vehicles are worth the expense, Bar’s Leaks Liquid Copper is the solution,” said Clay Parks, vice president of development. “It’s the only one-step copper block seal available.”
The product can simply be poured into the radiator and no draining of coolant is required, Parks said.
“Other products require a complete system flush, plus a number of additional steps, for a total of six to 10 hours to complete,” Parks added. “Customers who use products that aren’t antifreeze-compatible also have to add new coolant, further increasing the cost of the repair.”
Liquid Copper uses an advanced antifreeze-compatible sodium silicate liquid glass formula and works with all types and brands of antifreeze, including conventional green or blue (silicate-based) and extended life (red/orange) or yellow (OAT/HOAT).
It prevents leaks by forming a physical seal using organic and synthetic fibers, copper, and an ionic-modified mineral. The seal forms as the coolant and product flow through the leak, the company said, adding that a wetting agent cleans the sides of the hole or crack to prepare the surface for bonding. The first fibers catch on the side of the leak, building on each other to bridge the entire hole. The fibers then act as a sieve to trap more fibers, copper particles and minerals to create a composite seal.
The seal is cemented with liquid glass. As the temperature increases, the liquid glass hardens to make the seal permanent.
