Keep coolant clean and protected in heavy-duty diesel cooling systems with the Baldwin Cooling System Filter BW5139, a coolant spin-on with Baldwin's BTE formula. It's a direct-fit maintenance filter for a wide range of on-highway trucks and off-road equipment, including the 1981-1997 Ford L9000 [L6-14.6L], 2000-2004 International 9200I SBA [6-12.0L], 2000-2008 Ford F-650 and F-750 [L6-5.9L], plus Caterpillar and Komatsu equipment and many more — see the Buyer's Guide tab for the full list.
Filters both strain debris from the coolant and release additives that help maintain proper coolant condition; if the original filter is due for service, this replaces it. Made in the United States.
