Detailed Product Overview

Nissens 996265 is an engine coolant reservoir developed for thermal management in modern Mercedes-Benz cooling systems. The reservoir is made from plastic, uses a high-quality plastic cap, and includes a level sensor to support coolant level monitoring. With a 0.65L capacity and pressurized construction, it serves as a replacement tank for vehicles that require this specific OE-style configuration. This part cross-references A2465000049 and URO 2465000049 for the same application. Compatible with Mercedes-Benz CLA250, Mercedes-Benz CLA45 AMG, and Mercedes-Benz GLA250 models, Nissens 996265 supports cooling system service on 2014-2019 Mercedes-Benz CLA250, 2014-2019 Mercedes-Benz CLA45 AMG, and 2015-2019 Mercedes-Benz GLA250 vehicles. The part number 996265 is useful when matching the reservoir to the correct cooling system layout and sensor-equipped design.

Common Cooling System Issues Addressed

• Cracked or leaking coolant reservoir housing
• Faulty coolant level sensor warning
• Damaged or missing reservoir cap
• Pressure loss in the cooling system
• Reservoir replacement after age-related plastic wear

Installation Notes and Tips

Verify the reservoir shape, sensor connection, and cap style against the original unit before installation. Confirm the cooling system is fully depressurized and drained as needed, then inspect hoses, clamps, and mounting points for wear. Because mounting hardware and mounting bracket are not included, reuse or source the required vehicle-specific components separately if needed.

Quality Assurance

Nissens develops thermal and engine efficiency components for the aftermarket with a focus on consistent manufacturing standards. The 996265 coolant reservoir reflects that product approach with a sensor-equipped, pressurized design intended for the specified Mercedes-Benz applications.
