Detailed Product Overview

OSC Premium New Automotive Heater Cores are engineered as direct replacements for OE-style heater cores, and 98994 follows that approach with aluminum construction and corrosion-resistant tube plating. This heater core is a direct replacement for copper-designed units and is built to match original form and function in the HVAC system. It is a practical choice for drivers searching for a heater core for 2004-2012 Chevrolet Malibu, a heater core for 2005-2010 Pontiac G6, or a heater core for 2007-2009 Saturn Aura.

This part cross-references OSC 99305 for the same application.

Common Problems This Part Can Address

• Loss of cabin heat from a leaking or restricted heater core
• Coolant odor or moisture inside the passenger compartment
• Poor heater performance in high-mileage vehicles
• HVAC system inefficiency caused by internal corrosion or tube failure
• Repeat failures tied to original copper-style core design

Installation Notes and Tips

Verify vehicle year, make, and model before installation. This heater core is a direct replacement unit, so transfer and position the included foam and accessories as required by the HVAC case design. Flush the cooling system and inspect hoses, clamps, and coolant condition before installing the new core to help reduce contamination that can shorten service life.

Quality Assurance

Each heater core is individually pressure tested, and OSC uses cycle, vibration, burst, and environmental testing during development. The aluminum construction and plated tubes are selected to improve durability in demanding HVAC service.
