Rear Heater Core for 2000-2006 Chevrolet Tahoe & More - Spectra Premium 93057

Designed to supply heated air to the rear of the cabin, the Spectra Premium heater core 93057 is a rear unit that carries hot engine coolant through its aluminum core so air blown across it picks up heat. It fits many vehicles, among them the 2000-2006 Chevrolet Tahoe, 2000-2006 GMC Yukon and 2000-2006 Chevrolet Sonora with all engines, as a direct-fit replacement for the listed applications. See the Buyer's Guide tab for the full list.

• Aluminum construction: the core, tanks and tubes are all aluminum.
• 0.75 in connections: inlet and outlet pipes each measure 0.75 in in diameter.
• Specific fit: cataloged as a vehicle-specific part, and the listed applications use one.
• OE-level performance: Spectra Premium applies innovative engineering, manufacturing technology and quality control so its cores meet or exceed the performance of the original equipment they replace.

This Spectra Premium HVAC heater core serves the rear heating circuit. Signs that a heater core may need replacing include weak or no heat from the rear vents, a sweet coolant smell inside the cabin, fogged glass, damp carpet or unexplained coolant loss. Other cooling-system faults can cause similar symptoms, so diagnose the cause before replacing. Country of origin: China.
