Detailed Description

Nissens 72019 is an HVAC heater core designed for front-position applications in select Mercedes-Benz S-Class and CL-Class vehicles. It is compatible with 1992-2002 Mercedes-Benz S600, 1994-1999 Mercedes-Benz S320, S420, and S500, plus 1994-1995 Mercedes-Benz S350 front applications. It also covers 1992-1993 Mercedes-Benz 300SD, 300SE, 400SE, 500SEL, and 600SEL front applications, along with 1993 Mercedes-Benz 400SEL front applications and late 1993 Mercedes-Benz 500SEC and 600SEC applications.

Nissens develops thermal management components with a focus on consistent manufacturing quality and ongoing product development for the aftermarket. This heater core follows that approach with an aluminum-and-plastic design suited to restoring proper cabin heat in Mercedes-Benz S600, S500, and related chassis applications. Part number 72019 also cross-references 93727 for the same application.

Common Problems This Part Can Address

• Weak or uneven cabin heat
• Coolant seepage from a deteriorated heater core
• Restricted heat output caused by internal blockage
• Fogging or sweet coolant odor inside the cabin
• Loss of heater performance in front HVAC systems

Installation Notes and Tips

Verify the vehicle’s chassis break point and notes before ordering, especially for 1992-1993 applications listed from chassis/VIN A133639 and late 1993 coupe models. Confirm the heater hose routing and compare the core dimensions to the original unit before installation. Because pipe included is listed as no, reuse or source the required external connections as needed for the vehicle.

Quality Assurance

Nissens manufactures thermal components to a high production standard and continues to expand its aftermarket coverage as vehicle technology changes. The 72019 heater core is built as a quality replacement for Mercedes-Benz heating system service.
