Four Seasons HVAC Heater Core P/N:90011

Keep the cabin warm and the defroster clear with the FOUR SEASONS heater core (P/N 90011), an aluminum replacement core that routes hot engine coolant through its tubes and fins so the blower can push heated air into the passenger compartment. It installs in the front heater position and is a direct-fit replacement for a long run of Ford full-size vans, including the 1997-1998 Ford Club Wagon, the 1997-2004 Ford E150 Van, E250 Van and E350 Series Van, the 1999-2004 Ford Econoline, and the 1996-1999 Ford Econoline Super Duty — see the Buyer's Guide tab for the full list of applications.

• Aluminum core: tube-and-fin design that transfers coolant heat to the cabin airflow.
• Heavy-duty construction: built for durability in daily service.
• O.E. fit, form and function: quality-engineered to match the original.
• Independently tested for proven quality and performance.

As an hvac heater core, it's the part your heater and defrost circuits depend on. Signs the original may need replacing include weak or no heat, a sweet coolant odor inside the cabin, interior window fogging, or coolant seeping onto the floor. Backed by Four Seasons and over 50 years of mobile A/C experience.
