Four Seasons HVAC Heater Core P/N:92023

Bring warm air back to the cab with the Four Seasons heater core, MPN 92023 — a direct-fit replacement for a wide range of GM trucks and SUVs, including the 2003-2006 Chevrolet Silverado 1500 and 2500, GMC Sierra 1500, 2500 HD and 3500, Cadillac Escalade EXT, and the 2003-2007 Hummer H2. See the Buyer's Guide tab for the full list of 35 applications. Mounted in the vehicle's front heater case, this aluminum core routes hot engine coolant through its tubes while the blower pushes cabin air across the fins to warm the interior.

• Aluminum, heavy-duty construction: built for product durability.
• O.E. fit, form & function: quality-engineered to match the original core.
• Independently tested: verified for proven quality and performance.

Backed by Four Seasons' 50-plus years of mobile A/C experience. Weak or no cabin heat, a sweet coolant odor inside, foggy windows, a greasy film on the glass, or unexplained coolant loss can be signs the original heater core is leaking or clogged; if the core is the cause, this unit replaces it. As a chevy Silverado 1500 heater core and more, it drops into the listed applications.
