Four Seasons A/C Evaporator Core P/N:54876
Four Seasons 44129 a/c evaporator core for the 2007-2014 Kenworth T660 and other vehicles cools the cabin air as refrigerant flows through it.
Weak cooling at the vents or a refrigerant leak can mean the evaporator core has worn out. A failing expansion valve or compressor can lie behind those signs too, so find the cause before you replace the core.
It also fits the 2011-2014 Kenworth T680 and the 1987-2014 Kenworth T800, plus many more Kenworth trucks. For another Kenworth, or for engine details, go to the "Vehicles it fits" section.
