Description
Fleetguard WF2051 is a spin-on coolant (water) filter charged with DCA2 supplemental coolant additive (SCA) that replaces Cummins 209606. The filter screws onto a standard 11/16-16 UN-2B coolant filter head and slow-releases DCA2 chemistry to control liner cavitation, scale, and corrosion in heavy-duty diesel cooling systems built around Cummins B, C, L, M, N, and K series industrial and on-highway engines.

Applications
This coolant filter fits the following engine families equipped with a 11/16-16 coolant filter head and DCA2 cooling chemistry:
- Cummins B-series industrial / on-highway diesels
- Cummins C-series industrial / on-highway diesels
- Cummins L-series industrial / on-highway diesels
- Cummins M-series (M11) on-highway diesels
- Cummins N-series (NT/NTC/N14) on-highway diesels
- Cummins K-series industrial diesels
- Caterpillar, Komatsu, and Allis Chalmers diesels using the same 11/16-16 coolant-filter port and DCA2 program
Verify the coolant filter port thread size (11/16-16) and that your cooling system is on a DCA2 program before ordering. WF2051 is precharged for DCA2 maintenance, not for systems running ELC, OAT, or DCA4 chemistry.
