Description
BG Products K5901 Cooling System Flush Coolant Service Kit
Clean It. Protect It. Keep Your Engine Running Cool.
Give your vehicle's cooling system a complete two-step treatment with the BG Cooling System Clean & Protect Combo Pack. This professional-grade combination pairs BG Universal Cooling System Cleaner PN 540 with BG Universal Super Cool Coolant Additive PN 546 to first remove harmful deposits and then restore essential coolant protection.
Over time, rust, scale, oil, and mineral deposits can build up inside the cooling system. These deposits restrict coolant flow and interfere with heat transfer, increasing the risk of overheating and cooling system damage. Once the system is clean, BG Universal Super Cool helps restore coolant additive balance while providing protection against corrosion and foaming.
What's Included
1. BG Universal Cooling System Cleaner PN 540 — 12 FL OZ (354 mL)
Removes built-up rust, scale, oil, mineral deposits, and residues caused by coolant inhibitor breakdown.
2. BG Universal Super Cool Coolant Additive PN 546 — 12 FL OZ (354 mL)
Restores coolant additive balance and pH while helping protect against corrosion, rust, and foaming.
