Bar Leaks Radiator Stop Leaks 325ml Hector Core Freeze Concentrate Made in USA

Frequently Asked Questions... 

Will Bar’s Leaks plug my heater core? 

No, Bar’s Leaks Radiator Stop Leak will not clog 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. 

What are the dosage recommendations? 

Use one bottle for regular size cooling systems; this covers most 6, 8 and 10 cylinder engines. Use 1⁄2 bottle for four cylinder engines. One bottle treats up to 4 gallons. For larger systems use 1 bottle for every 4 gallons of capacity. 

How long does it take to see results? 

We recommend you drive/idle the vehicle for 15 to 30 minutes. In most cases the leak will be sealed instantly, but others will require up to 30 minutes. If the leak is not sealed in 30 minutes, a second application may be required or mechanical repair may be needed.
