Why should I add Bar's Leaks Anti-Rust & Water Pump Lube

Simply stated, anti-freeze is not enough to maintain your cooling system.  Water pump lubrication and inhibitors naturally wear out during normal coolant circulation.  These inhibitors are very important because they help prevent the formation of rust and corrosion, a prime cause of leaks and seepage.  Anti-rust inhibitors must be present within the coolant AT ALL TIMES if the system is to function properly.  

Yes, Bar's Leaks Anti-Rust with Water Pump Lube is compatible with all types of coolant, even extended-life anti-freeze.
