BTE Liquid Coolant System Treatment/Additive - 1.89L | 400CS5009

Baldwin CS5009 BTE Liquid Coolant Additive is a heavy‑duty, ready‑to‑use supplemental coolant treatment designed to maintain optimal protection and performance in diesel and heavy‑duty cooling systems. Formulated to restore and stabilize coolant chemistry as additives deplete, CS5009 helps prevent cavitation erosion, liner pitting, corrosion, scale formation, and foaming — extending the life of engine blocks, radiators, and other cooling components. Ideal for fleets, commercial trucks, buses, and industrial equipment, it keeps coolant systems reliably protected between service intervals.

• Maintains coolant inhibitor levels to prevent cavitation, corrosion, and scale
• Protects radiators, water pumps, and engine blocks from erosion and foaming
• Compatible with 40–60% ethylene‑glycol antifreeze systems
• Simple dosing for easy maintenance and long-term protection
• Extends cooling system component life and reduces repair costs
