APDI 9010187 HVAC Heater Core

APDI 9010187 Heater Core for GM HVAC Systems

The APDI 9010187 heater core is an aluminum HVAC heater core for GM applications that need reliable cabin heat and stable coolant-to-air transfer. Built with aluminum core and tank construction, it measures 6-1/4 in. high, 7-1/4 in. wide, and 1 in. thick with 5/8 in. inlet and 3/4 in. outlet pipe diameters.

APDI’s Heater Core line focuses on direct-fit HVAC replacement parts for GM vehicles, and this APDI 9010187 heater core follows that approach with application-specific sizing and tube dimensions for service work on older compact and midsize platforms.

Detailed Description

This heater core is built for GM heating systems that use a compact aluminum core with matching aluminum tanks. The APDI 9010187 is a practical replacement for vehicles such as the Buick Skylark, Pontiac Grand Am, Chevrolet Cavalier, and Oldsmobile Achieva, where correct tube size and core dimensions matter for proper heater performance and fitment. This part cross-references Four Seasons 90496 for the same application.

What It Helps Address

• Weak or inconsistent cabin heat
• Coolant seepage from a damaged heater core
• Restricted heat transfer from internal corrosion or blockage
• HVAC performance loss in older GM heating systems
• Replacement needs after a leaking or clogged factory core
