Bring warm air back through the dash vents with the Spectra Premium HVAC Heater Core 99331 — a direct-fit 2002-2008 Dodge Ram 1500 heater core that also serves a wide span of heavy-duty Ram trucks. It drops in for the 2002-2008 Dodge Ram 1500, the 2002-2010 Dodge Ram 2500 and 3500, the 2002 and 2005-2008 Dodge Ram 4000, and the 2008-2010 Dodge Ram 5500 (all engines). Hot engine coolant flows through the core while the blower pushes air across its fins to heat the passenger compartment.

  • All-aluminum construction: aluminum tanks, tubes, and core.
  • Inlet and outlet pipes: 0.625 in diameter on both connections.
  • OE-level performance: engineered to match or surpass the performance of the heater core it replaces.
  • Model-specific fit: a specific-fit replacement, with one core used per application.

If your truck's original core is behind weak cabin heat, a sweet coolant odor inside, fogged windows, or coolant pooling on the passenger-side floor, this unit replaces it — diagnose the cause of any heating or coolant-loss issue first, since these signs can have other sources.
