Evaporator Core & Heater Core

Find New OEM A/C evaporator cores and heater cores for GM vehicles. Our factory-original HVAC cores are sourced from GM surplus — the exact tube configuration, fin density, and connection port size for your specific HVAC case assembly.

Evaporator and heater core replacement is a labor-intensive repair — the dashboard must be partially or fully removed to access the HVAC case. Using an OEM core ensures the correct fit within the case and eliminates the risk of refrigerant leaks or coolant leaks that result from dimensional mismatches common with aftermarket cores.

Verify part numbers against your vehicle's HVAC system configuration (single-zone, dual-zone, rear HVAC) before ordering. Contact us for fitment assistance.
