Detailed Description

APDI 9010281 heater core is a GM heater core replacement for vehicles that use a compact aluminum heat exchanger in the HVAC case. It is listed for 1999-2015 model-year coverage across Chevrolet, GMC, and Cadillac platforms, including Silverado 1500, Silverado 2500 HD, Sierra 1500, Sierra 2500 HD, Tahoe, Yukon, Suburban, Avalanche, and Escalade applications. This part number, 9010281, also cross-references Four Seasons 90050 for the same application.

For buyers searching for a heater core for Chevrolet Silverado 1500, GMC Sierra 1500, or Cadillac Escalade front HVAC service, this APDI unit provides the specified aluminum construction and quick-connect pipe sizing needed for the listed GM fitments.

What It Helps Address

• Loss of cabin heat from a leaking or restricted heater core
• Coolant odor inside the vehicle from heater core seepage
• Fogging or film on the windshield caused by HVAC coolant leakage
• Uneven or weak heat output from the dash vents
• Service replacement for damaged GM heater core assemblies

Installation Notes and Tips

Verify the vehicle year, make, model, and HVAC configuration before ordering. Several listed applications require Automatic Temperature Control or Heavy Duty Heater configurations, and some fitments are front-position units. Confirm the 3/4 quick-connect inlet and outlet pipe connections match the original part before installation.

Because heater core replacement often requires access to the HVAC case, inspect related hoses, clamps, and coolant condition during service. Proper system bleeding after installation helps restore normal heater performance.

Quality Assurance

APDI supplies replacement HVAC components for GM applications, and this heater core is built with aluminum core and tank materials to match the listed specifications. Part number 9010281 is cataloged for direct-fit service across the supported Chevrolet, GMC, and Cadillac vehicles.
