Can Bar’s Leaks® Liquid Copper™ Intake & Radiator Stop Leak be installed in existing antifreeze?
Yes, unlike other copper stop leak products, Liquid Copper™ One Step sealer contains an antifreeze compatible sodium silicate formula, so draining of the cooling system is not required as long as manufactures recommendations are followed. It also can be used in water alone however, a second bottle of Liquid Copper™ is recommended to be added to the system once antifreeze is installed.
Will it work in the new extended life antifreeze?
Yes, Liquid Copper™ is compatible with both conventional green or blue (silicate-based) and extended life red/orange or yellow (OAT/HOAT) 50-50 mix antifreeze.
Do I need to drain my cooling system after using Liquid Copper™?
No, this product is designed to be left in the cooling system to protect from future leaks.
How does this type of product work?
It stops leaks by forming a physical plug with organic and synthetic fibers, copper and an ionic modified mineral. The plug forms as the coolant and sealer flow out of the leak. A wetting agent cleans the sides of the hole and prepares the surface for bonding. The first fibers catch on the side of the leak or hole eventually bridging the entire hole. The fibers now act as a sieve trapping more fibers, copper particles and minerals, creating a composite plug. This plug is stabilized or cemented with a liquid glass. The liquid glass hardens with increased temperature and completes the seal.
Results should be noticeable within 20 to 30 minutes. If the leak is not sealed in 30 minutes of running, mechanical repair may be needed.
Use 1 (one) bottle for regular size cooling systems, this covers most 4, 6, 8 and 10 cylinder engines. For small cooling systems, such as 4 cylinders with no air conditioning, use 1⁄2 (half) of bottle. For other small systems use approximately 3 ounces per gallon of cooling capacity. In larger systems, use 1 (one) bottle for every 6 gallons of cooling system capacity.
Will Liquid Copper™ plug my heater core?
No, Liquid Copper™will not plug a clean heater core. Note: If using Bar’s Leaks® to stop heater core leaks, make sure you turn your heater control to HOT. Some vehicles have a valve that controls coolant flow through the core and is only opened in the HOT position.
Can I install Liquid Copper™ in my overflow reservoir?
For best results Liquid Copper™ should not be installed in a regular overflow tank unless it has a screw on pressurized cap. If you do not have access to your radiator, remove top hose where it connects to the top of the radiator and install product in hose. Reattach hose and tighten clamp.
Will this work in both domestic and import cars and trucks?
Yes, Liquid Copper™ will work in all types of water cooled vehicles.
I accidently added the Liquid Copper™ into my gas tank, what should I do?
Liquid Copper™ is only designed to be added to the cooling system. If the product is accidentally installed in the gas tank, the tank should be removed and cleaned out by a professional mechanic.
I accidently added the Liquid Copper™ into my engine oil, what should I do?
If the product is accidently installed in the engine oil and the engine has not been started, in many cases you can remove the valve cover where installed and drain the oil leaving the drain plug off. Then use an engine flush washing out the head giving special attention to the oil return holes that run down to the oil pan. Clean these out and pour the engine flush down these holes flushing everything into the oil pan and out the drain hole. If the engine has been run, the vehicle needs to be towed to a professional mechanic for evaluation. This might include taking the engine apart to clean all of the internal parts.
