What This Heater Core Helps Address

• Weak or uneven cabin heat
• Coolant odor inside the vehicle
• Fogging from heater core leakage
• Restricted coolant flow through the HVAC heater circuit
• Heat loss caused by a damaged or corroded core

Installation Notes and Tips

Verify the inlet and outlet pipe size, core dimensions, and vehicle fitment before installation. Replace the included O-rings during service and inspect the HVAC housing, coolant lines, and seals for wear or residue. Proper system bleeding after installation helps restore normal heater performance.

Quality Assurance

Nissens manufactures and tests heater cores to OE specifications. Their validation process includes vibration, pressure impulse, thermal expansion, corrosion, and burst testing to reduce the risk of leakage, poor heating output, or contamination from oil residue. Part number 70979 is finished for smooth installation in the HVAC module and is listed for 2005-2007 Chrysler 300, 2006-2007 Dodge Charger, and 2005-2007 Dodge Magnum.
