A cooling system filter sits in the engine's coolant circuit to trap rust, scale, casting sand, and other debris that circulate as coolant flows, helping keep the radiator, water pump, and heater passages free of the abrasive particles that cause wear and clogging.
Signs a coolant filter may be due for replacement include reduced coolant flow or visible contamination. If a clogged or spent filter is the cause, installing a fresh BW5137 helps restore the intended filtration in the cooling circuit. Manufacturer part number BW5137 from Baldwin Filters.
What does the Baldwin BW5137 do?
It filters the engine coolant, trapping rust, scale, casting sand, and debris that circulate through the cooling system so those particles don't wear or clog components like the radiator and water pump.
Will it fit my truck?
It's cataloged for 114 medium- and heavy-duty applications, including the 1993-1999 Ford F-800 and 1987-2018 Kenworth T800. Check the Buyer's Guide tab to confirm your exact year, make, and model.
How often should I replace it?
Replace it at the coolant service intervals in your vehicle's maintenance schedule, or sooner if you notice reduced coolant flow or heavy contamination.
Why filter engine coolant?
Coolant picks up rust, scale, casting sand, and debris over time; filtering removes these abrasive particles to help protect the radiator, water pump, and other cooling-system passages from wear and clogging.
