Four Seasons HVAC Heater Core P/N:90057
Keep warm air flowing to the cab with the Four Seasons heater core 96109, an aluminum core that routes hot engine coolant through its tubes and fins so the blower can push heated air into the cabin. It drops in as a direct-fit replacement for the 1996-1998 Ford A9513, 1997 Ford A9522, and 1989 Ford LTS8000, plus Sterling Truck A9500 (1999-2003), A9513 (1999-2001), AT9500 (2001-2006), L7500 (2001-2006) and more — see the Buyer's Guide tab for the full list.
Signs the original may need replacing include weak or no heat, a sweet coolant smell in the cab, fogged windows, or coolant seeping into the footwell. If a failed heater core is the cause, this unit replaces it. Backed by Four Seasons and its decades of mobile A/C experience.
