WF2131 - Coolant Filters

The Fleetguard® DCA2 Chemical Water Filter (SKU: WF2131) is an essential maintenance component for heavy-duty engines, offering a dual-action defense system to ensure long-term cooling system health. Engineered specifically for engines utilizing Fleetcool and Fleetcool EX technologies, this filter serves as both a high-efficiency mechanical strainer and a chemical replenishment center. At its core, the WF2131 provides superior filtration, capturing harmful contaminants, scale, and debris that can compromise water pump seals and clog radiator passages. Beyond physical filtration, the filter is pre-loaded with Supplemental Coolant Additives (SCAs). These chemical additives are released into the coolant stream to rehabilitate the system, providing a critical protective barrier against liner pitting, cavitation, and corrosion. By maintaining the proper chemical balance, the DCA2 filter prevents the degradation of metal surfaces and extends the service life of your engine components. Designed for easy installation and reliable performance under extreme thermal stress, the Fleetguard® WF2131 is the professional choice for operators looking to minimize downtime and avoid costly cooling system failures. Whether you are performing a routine service or rehabilitating a system, this filter ensures your coolant remains effective, balanced, and clean, keeping your fleet running at peak efficiency.
