Detailed Description

This heater core is built for 2010-2016 Land Rover LR4, front, and 2010-2013 Land Rover Range Rover Sport applications. Nissens manufactures and tests heater cores to OE standards, using life testing methods that evaluate vibration, pressure impulse, thermal expansion, corrosion, and burst resistance to reduce the risk of leakage, weak heating output, or residue-related issues. Part number 707310 is shaped for smooth installation into the HVAC module mounting cassette and supports proper cabin heat delivery in Land Rover LR4 and Range Rover Sport service repairs. This part cross-references Land Rover OE numbers AH2218D557AA and LR015348 for the same application.

Common Issues Addressed

• Weak or uneven cabin heat
• Coolant leakage from the heater core area
• Restricted heat transfer inside the HVAC system
• Fitment problems during heater core replacement
• Corrosion-related heater core failure

Installation Notes and Tips

Verify the vehicle’s HVAC configuration and compare the original core dimensions, inlet, and outlet pipe size before installation. For 2010-2016 Land Rover LR4 front HVAC service and 2010-2013 Range Rover Sport heater core replacement, confirm that the core seats correctly in the mounting cassette and that all hose connections are clean and properly aligned. Flush the cooling system as needed before installing the new heater core to help protect the replacement part and restore heat performance.

Quality Assurance

Nissens heater cores are manufactured and tested to OE specifications, with validation that includes vibration, pressure impulse, thermal expansion, corrosion, and burst testing. These controls support consistent fit, heat transfer, and leak resistance in demanding HVAC service applications.
