WF2126 - Coolant Filters

The Fleetguard® DCA4 Chemical Water Filter (SKU: WF2126) is an essential dual-action solution for maintaining the long-term health and efficiency of your heavy-duty engine’s cooling system. Engineered to provide high-efficiency filtration alongside chemical protection, this premium spin-on filter ensures your engine operates at peak performance even under demanding conditions. The WF2126 is specifically designed to rehabilitate and maintain ES Compleat™ or similar coolant technologies. It works by slowly releasing Supplemental Coolant Additives (SCAs) into the system, which are critical for preventing liner pitting, cavitation, and scale buildup. Without these additives, the metal surfaces within your engine are vulnerable to corrosive damage that can lead to catastrophic failure and expensive downtime. Beyond chemical replenishment, this filter features robust media designed to capture harmful contaminants, such as dirt, debris, and rust particles, preventing them from circulating through the radiator and water pump. By combining mechanical filtration with chemical fortification, the Fleetguard® DCA4 filter extends the life of your coolant and protects internal components from premature wear. Easy to install and built to withstand high-pressure environments, the WF2126 is the professional choice for fleet managers and operators looking to reduce maintenance costs and maximize engine longevity. Keep your cooling system balanced, clean, and fully protected with Fleetguard’s industry-leading filtration technology.
