Common Heater Core Problems

• Weak or uneven cabin heat in Mercedes-Benz CL500, S500, or E320 models
• Coolant odor inside the cabin from a leaking heater core
• Fogging or film on the windshield caused by HVAC leakage
• Restricted heat output from internal blockage or corrosion
• HVAC performance loss in vehicles with aging factory heater cores

Installation Notes

Verify the vehicle’s HVAC configuration and compare the original core dimensions before installation. This part does not include pipes, so reuse or source the correct vehicle-specific connections as needed. Because fitment varies across Mercedes-Benz platforms, confirm the application against the existing heater core and HVAC housing before assembly.
