PN 546

BG Universal Super Cool® is a coolant additive specifically formulated to provide outstanding protection for all modern coolant systems.

Over time, the protective additives in an engine coolant become depleted, thus rendering the coolant acidic and incapable of protecting the components in the system. This results in damaging corrosion in the formation of rust, scale and other debris that prevent proper engine temperature regulation. Left untreated, this condition may cause leaks and overheating and other drivability problems.

BG Universal Super Cool® is a unique formulation that restores coolant to its peak level of protection. It is designed for use in conventional, long life, hybrid, heavy duty and diesel coolants. As an important part of the BG Cooling System Service, it restores critical additive balance, proper coolant pH, and provides protection against foaming and metallic corrosion.
