Keep warm air reaching the cabin with the Four Seasons heater core 90070, an aluminum front heater core engineered for O.E. fit, form and function. It fits many vehicles, among them the 1998-2002 Honda Accord, 2003-2008 Honda Pilot and 1999-2004 Honda Odyssey. See the Buyer's Guide tab for the full list and engine details.
A heater core is a small heat exchanger in the vehicle's heating system. Hot engine coolant circulates through it while the blower moves air across it, which warms the cabin and supports the defroster. Four Seasons backs this part with over 50 years of mobile A/C experience.
- Aluminum core: Four Seasons describes the 90070 as an aluminum heater core.

Signs a heater core may need replacing include weak or no cabin heat, a sweet coolant smell inside the vehicle, a windshield that fogs easily, damp carpet, or coolant loss with no visible external leak. If a leaking or restricted heater core is the cause, this part replaces it. Diagnose the cause before replacing parts, follow the vehicle's service procedure, and refill and bleed the cooling system after installation.
