WF2051 - Coolant Filters

The Fleetguard® WF2051 DCA2 chemical water filter is a critical component for maintaining the longevity and efficiency of your heavy-duty cooling system. Engineered specifically for use with Fleetcool and Fleetcool EX technologies, this dual-action filter provides a comprehensive solution for both mechanical filtration and chemical protection. The WF2051 does more than just trap contaminants; it is pre-loaded with high-quality Supplemental Coolant Additives (SCAs) that are gradually released into the system. These DCA2 chemicals are essential for rehabilitating depleted coolant, providing a robust defense against liner pitting, scale buildup, and internal corrosion. By maintaining the proper chemical balance, this filter prevents the overheating and component failure often caused by mineral deposits and acid formation. Beyond its chemical benefits, the filter features premium media designed to capture harmful debris, silt, and rust particles that can cause premature wear on water pump seals and radiators. This ensures a cleaner, more efficient flow throughout the engine's cooling passages. Easy to install and built to withstand the rigors of high-mileage operation, the Fleetguard® WF2051 is an indispensable tool for fleet managers and owner-operators looking to extend service intervals and lower total cost of ownership. Protect your investment and ensure peak thermal performance with the industry-standard in cooling system maintenance.
