URO 1665000049 Engine Coolant Reservoir - Radiator

Engine Coolant Reservoir Overview

This URO engine coolant reservoir is built for Mercedes-Benz cooling system service where OE-style fit and reliable sealing matter. Part number 1665000049 is engineered to match original dimensions and connection points for a direct replacement on supported applications.

Compatible With Mercedes-Benz GLE, GLS, GL, and ML models across the listed years, this reservoir is made to handle engine heat and the demands of the cooling system environment. It is factory pressure-tested to help confirm leak resistance before installation.

Key Features

• Precision-molded to OE dimensions for proper sensor and hose connection alignment
• Heat-resistant materials for cooling system use
• Factory pressure-tested for sealing verification
• Direct replacement design for supported Mercedes-Benz applications
• URO part number 1665000049 for easy identification

Detailed Description

Engine coolant reservoirs store excess coolant and help maintain stable system volume as temperatures change. This URO reservoir is designed around OE dimensions so it matches original mounting and connection points on supported Mercedes-Benz GLE, GLS, GL, and ML applications. The result is a service part that follows the factory layout and works with original sensors and connections.

Part number 1665000049 is a practical choice for cooling system repair when the original reservoir is cracked, leaking, or no longer sealing correctly. This part cross-references URO-018236 for the same application.

What It Helps Address

• Coolant loss from a cracked or leaking reservoir
• Poor sealing at the tank or connection points
• Fitment issues with original sensors or hoses
• Heat-related plastic deterioration in the cooling system
• Pressure retention problems during normal engine operation

Installation Notes and Tips

Verify the reservoir shape, sensor connection style, and hose routing against the removed part before installation. Inspect the cap, hoses, and adjacent cooling system components for wear or contamination so the new reservoir can be installed into a clean, sealed system. After installation, refill and bleed the cooling system according to the vehicle service procedure.

Quality Assurance

URO lists guaranteed fitment, factory pressure testing, and a 24-month unlimited mileage warranty for this part number 1665000049.
