Nissens 98439 Exhaust Gas Recirculation (EGR) Valve

Nissens EGR Valve for Mercedes-Benz E300

The Nissens 98439 exhaust gas recirculation valve is built for precise EGR control and stable combustion performance. It is a direct-fit emission control component for the 1995 Mercedes-Benz E300, with a pneumatic operation type and an included gasket or seal for proper sealing at installation.

Key Features

• Pneumatic EGR valve design for controlled exhaust gas recirculation
• Includes gasket or seal for installation sealing
• Manufactured with high nickel content alloys for heat resistance
• Tested for calibration, fit, and reliable operation
• OE-style replacement for Mercedes-Benz E300 emission control service
• Part number 98439 for accurate ordering and lookup

Detailed Description

Nissens 98439 is an exhaust gas recirculation valve engineered to restore proper EGR flow on the 1995 Mercedes-Benz E300. By recirculating exhaust gases in a controlled manner, the valve supports cleaner combustion and helps the engine maintain correct emissions behavior. Nissens uses heat-resistant materials, including high nickel percentage alloys, to handle the thermal demands of the EGR system, and each valve is tested for calibration and fit before release. This part cross-references OE-style applications such as 0021400060 and 0021401760 for the same application.

What It Helps Address

• EGR flow faults that trigger emissions-related warning lights
• Rough idle caused by improper exhaust gas recirculation
• Combustion issues linked to a sticking or worn EGR valve
• Excessive emissions from incorrect recirculation control
• Driveability problems on a Mercedes-Benz E300 with a failing EGR valve

Installation Notes and Tips

Fits 1995 Mercedes-Benz E300, N/A. Confirm the pneumatic EGR system layout and match the valve to the original part number before installation. Inspect the mating surfaces, replace the seal provided with the valve, and verify vacuum routing and system cleanliness so the replacement can operate correctly. The part number 98439 should be used to confirm application details during service.

Quality Assurance

Nissens tests this EGR valve for calibration, fit, and reliable operation in vehicle. The use of high nickel content alloys supports heat resistance in demanding exhaust gas recirculation service, making Nissens 98439 a technical replacement choice for the Mercedes-Benz E300.
