Four Seasons HVAC Heater Core P/N:90010

Help bring warm air back to the cabin with the Four Seasons heater core, part number 90010, an aluminum front heater core that carries hot engine coolant through its core so the blower can send heated air to the vents and defroster. It fits many vehicles, among them the 1995-2001 Ford Explorer, 1995-2011 Ford Ranger and 1995-2010 Mazda B2300.

Four Seasons engineers and tests its products and brings more than 50 years of mobile A/C experience to the job. This HVAC heater core is a direct-fit replacement for the listed applications.

• Aluminum heater core: passes heat from the engine coolant flowing through it to the air moving across it.
• Heavy-duty construction: built with product durability in mind.
• O.E. fit, form and function: engineered to match the original part.
• Independently tested: checked by an outside tester for quality and performance.

Signs a heater core may need replacing include weak or no cabin heat, a sweet coolant smell inside the vehicle, a greasy film fogging the inside of the windshield, damp front floor carpet, or coolant loss with no visible outside leak. Diagnose the cause first. If a leaking or clogged core is the problem, this unit replaces it. See the Buyer's Guide tab for every vehicle and engine this part fits.
