Detailed Description

URO part number 2055000049 is an engine coolant reservoir designed for Mercedes-Benz cooling systems that use a radiator-mounted tank. It is shaped to match original equipment dimensions, helping maintain proper fit with factory sensors, hoses, and mounting points. This makes it a strong replacement choice for Mercedes-Benz C300, GLC300, and E450 cooling system repairs where the reservoir has become brittle, warped, or leaking.

This reservoir also cross-references VAICO V30-2667 and Rein EPT0132 for the same application. Use it when you need a replacement coolant expansion tank that matches the OE-style layout without changing the surrounding cooling system components.

Common Problems This Part Can Address

• Coolant leaks from a cracked or aged reservoir
• Loss of system pressure caused by a damaged tank
• Warning lights or low coolant level concerns tied to reservoir failure
• Fitment issues after replacing a worn OE coolant expansion tank
• Heat-related plastic deterioration in the engine bay

Installation Notes and Tips

• Verify radiator position fitment before ordering; this part is listed for radiator-mounted applications and select N/A-position vehicles noted in the fitment data.
• Transfer or inspect the cap separately if your vehicle requires one; cap type is twist.
• Check hoses, seals, and sensor connections for wear before installation.
• Confirm the cooling system is properly filled and bled after replacement.

Quality Assurance

This URO coolant reservoir is factory pressure-tested and backed by a 24 Month Unlimited Mileage Warranty. It is built from quality materials intended to withstand engine heat and the demanding environment of the cooling system.
