What It Helps Address

• Poor heater performance caused by internal corrosion or blockage
• Repeat failures in high-mileage HVAC systems
• Fitment issues from non-OE-style replacement parts

Installation Notes and Tips

Verify the vehicle year, make, model, and core size before installation. Some Dodge Dakota and Dodge Durango applications list 2 inch core or 5/8 inch core notes, and several Chrysler, Dodge, and Plymouth vehicles are noted for air conditioning system configurations. Confirm the existing heater core dimensions and HVAC layout against the vehicle before removal.

Use clean coolant and inspect related HVAC components, hoses, and seals during service. Proper flushing and careful reassembly help protect the new heater core and support consistent heat output after installation.

Quality Assurance

OSC Premium heater cores are built from premium aluminum, pressure tested individually, and manufactured with cycle, vibration, burst, and environmental testing in mind. The cadmium-plated tube design is intended to help reduce premature failure in demanding service conditions. Part number 98604 is produced as an OE-style replacement for copper-core applications.
