Product Details

Built by Nissens, part number 72029 is an HVAC heater core developed for thermal system service in select Mercedes-Benz CLS and E-Class vehicles. The compact core measures 7.0900 in. high, 8.4300 in. long, and 0.9800 in. wide, with aluminum construction throughout for the core and tanks. This heater core is a practical replacement choice for Mercedes-Benz E350, E550, E320, E63 AMG, E500, E55 AMG, CLS550, CLS63 AMG, CLS500, and CLS55 AMG applications across the listed model years.

Nissens focuses on thermal and engine-efficiency components, and this 72029 heater core reflects that product approach with brazed fin construction and application-specific pipe inclusion. It is a fitment-based replacement for Mercedes-Benz heating system service where the original heater core has failed or lost performance.

What It Helps Address

• Weak or uneven cabin heat
• Coolant odor inside the vehicle
• Interior windshield fogging caused by heater core leakage
• Loss of heater performance from a restricted or corroded core
• Coolant seepage in the HVAC housing area
