Coolant System Protection Additive, BTA PLUS Formula - 1.89L | 400CS5058

Baldwin CS5058 BTA PLUS Liquid Coolant Additive is a premium heavy‑duty coolant treatment designed to keep diesel and industrial cooling systems running at peak performance. By replenishing depleted inhibitors, it protects against cavitation, corrosion, erosion, scale buildup, and foaming. Easy to use and compatible with most ethylene‑glycol antifreeze systems, CS5058 extends the life of radiators, pumps, and engine liners — helping fleets and commercial operators reduce maintenance costs and avoid unexpected downtime.

• Premium BTA PLUS liquid coolant additive — suitable for heavy‑duty diesel and industrial cooling systems. 
• Helps replenish depleted inhibitors (nitrite, silicate, phosphate, etc.) to protect against cavitation, liner pitting, corrosion, and scale build‑up. 
• Compatible with ethylene‑glycol based antifreeze (0‑60%), making it usable in most standard heavy‑duty systems (not for “organic acid” / OAT‑type coolants). 
• Easy maintenance dosing: pre‑charge 1.25 units per gallon, then maintenance dose 1.25 units per 4 gallons every 12,000–15,000 mi (or 300‑350 hours). 
• Reduces coolant‑system maintenance: helps extend the service life of radiators, pumps, liners, and hoses, lowering repair costs and downtime. 
• Ideal for fleets and commercial equipment — a reliable way to maintain coolant chemistry without needing a coolant filter.
