BG AB Complete rejuvenates worn out coolant, giving it back its corrosion prevention abilities.
When water and glycol-based coolants wear out, they become corrosive to the metal components in a vehicle’s cooling system. Corrosion and deposits create blockages in water pumps, radiators and heater cores.
BG AB Complete:
• Contains essential cooling system inhibitors
• Immediately restores the corrosion protection to water and glycol based coolants
• Protects cooling system metals by inhibiting corrosion, preventing foaming and neutralizing acidic contaminants
