Baldwin Cooling System Filter P/N:BW5137
Baldwin Filters
Baldwin BW5178 cooling system filter for the 1995-2007 Mack LE 6-cylinder 11.9L and other vehicles is a spin-on filter that cleans the engine coolant.
Dirty or rusty-looking coolant, scale in the cooling system or an engine that runs hotter than normal can mean the cooling system filter is due for a change. Overheating alone does not prove the filter is at fault; a weak thermostat is another common cause.
The 2001-2008 Mack CV 6-cylinder 11.9L, the 1981-1993 Mack RD 6-cylinder 11.0L, the 1990-2004 RD 6-cylinder 11.9L and the 1995-1996 RD 6-cylinder 11.0L all fit this filter, and so do many other Mack vehicles.
