Frequently Asked Questions
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.
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.
What are the dosage recommendations?
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.
