Four Seasons HVAC Heater Core P/N:90052

Bring warm, defogging air back to the cabin with the Four Seasons heater core, part number 90052 — a front-mounted aluminum core that installs as a direct-fit replacement across a wide range of GM full-size vans and medium-duty trucks. It fits the 1996-2024 Chevrolet Express 2500 and Express 3500, the 2009-2024 Express 4500, the 1996-2014 Express 1500, the 2009-2020 Express Cargo and Express Pasajeros, the 2001-2002 Chevrolet G30, plus the matching 1996-2024 GMC Savana 2500 and 3500, and the 2003-2009 Chevrolet/GMC Kodiak and TopKick C4500-C8500 trucks. See the Buyer's Guide tab for the full application and engine list.

Inside the HVAC case, engine coolant circulates through the core while the blower pushes cabin air across its fins to warm the interior and help clear the glass. If a leaking or clogged heater core is the cause of weak heat, a sweet coolant smell, or fog on the inside of the windshield, this replaces it.
