Detailed Description

Built by Nissens, part number 72028 is an HVAC heater core developed for thermal system service in Mercedes-Benz vehicles. The aluminum core and aluminum tank design supports efficient cabin heat delivery, while brazed cooling fins help maintain heat transfer across the core surface. This unit cross-references Dorman - HELP 93833 for the same application. It also cross-references Spectra Premium 99383 for the same application.

Compatible With 2009-2018 Mercedes-Benz G550, 2017-2018 Mercedes-Benz G550 4x4, 2013-2018 Mercedes-Benz G63 AMG, 2016-2018 Mercedes-Benz G65 AMG, and additional Mercedes-Benz SL-Class, CLK-Class, C-Class, and G-Class fitments listed below. The Nissens 72028 is a practical replacement choice when servicing the heater core in vehicles such as the Mercedes-Benz SL550, C350, or G500.

What It Helps Address

• Weak or uneven cabin heat output
• Coolant seepage from a deteriorated heater core
• Restricted heat transfer caused by internal buildup
• HVAC performance issues tied to a failing core
• Replacement needs during cooling system or dash service

Installation Notes and Tips

Verify the vehicle’s year, model, and HVAC configuration before installation. Compare the original core dimensions and pipe layout to confirm fitment, since pipes are not included. On Mercedes-Benz applications such as the G550, SL550, and C320, access may require removal of interior trim or HVAC components, so inspect seals, hoses, and coolant condition during service.

Quality Assurance

Nissens develops thermal and engine-efficiency components with a focus on consistent manufacturing quality and ongoing aftermarket application coverage. Part number 72028 reflects that approach with an aluminum construction and brazed-fin design suited to select Mercedes-Benz heater core replacements.
