Four Seasons HVAC Heater Core P/N:92003
Bring the heat back to your cabin with the Four Seasons Heater Core (MPN 90082) — the coolant-fed core your Mustang heater core system relies on to warm incoming air. It's a direct-fit replacement for the 2001-2004 Ford Mustang, with per-engine coverage detailed on the Buyer's Guide tab. Hot engine coolant flows through the core's aluminum tubes while the blower pushes cabin air across its fins, transferring that heat into the passenger compartment; a corroded, clogged, or leaking core can leave you with weak heat, a sweet coolant smell, fogged glass, or damp carpet — signs this part may need replacing.
Backed by Four Seasons' decades of mobile A/C and heating experience. Always drain the cooling system and confirm the correct application before installing.
