Four Seasons HVAC Heater Core P/N:96135

Bring warm air back to the cab with the Four Seasons heater core (P/N 96135), an aluminum-core direct-fit replacement built for a wide range of Western Star trucks — including the 1985-2002 4900, the 1988-1999 4800, the 1997-2002 4900E, and the 1990-2001 5900. See the Buyer's Guide tab for the full application list. This HVAC heater core routes hot engine coolant through its aluminum core while the blower pushes cabin air across it, transferring that heat into the interior for defrost and comfort.

• Aluminum core: transfers coolant heat to the passenger compartment.
• Heavy-duty construction for lasting durability.
• O.E. fit, form and function: engineered to match the original unit and drop into the listed applications.
• Independently tested for proven quality and performance.

Backed by more than 50 years of Four Seasons mobile A/C experience. If a leaking or clogged heater core is the cause of weak heat, coolant smell, foggy windows, or damp carpet, replacing it with this unit addresses those issues at the source. Always diagnose the cause before replacing.
