Protect wet-sleeve diesel cooling systems from liner pitting with the Fleetguard Engine Coolant Filter. This coolant filter contains a controlled-release additive charge formulated to reduce cavitation and scale formation on internal metal surfaces. Regulating additive dispersion within the coolant stream helps limit localized liner erosion under high-load operation. A reinforced internal support structure maintains stability during elevated coolant flow rates common in heavy-duty applications. The Fleetguard WF2121 is used in Oshkosh S Series with Cummins ISM11, Kenworth T400 with Cummins ISL G 8.9L, Western Star 4964FXL with ISM11, and Cummins QSX11.9 and ISM02 engine applications.
