Product Details

The Genuine Mercedes 1265001549 Engine Coolant Expansion Tank is an OEM replacement reservoir designed to maintain proper cooling system pressure and coolant levels. This genuine factory part stores excess coolant as the engine heats up, allowing the radiator to operate at peak efficiency while preventing coolant loss and overheating.

Key Features:

  • Genuine Mercedes-Benz OEM quality for precise fit and long-lasting durability
  • Engineered to withstand extreme engine temperatures and pressure fluctuations
  • Direct replacement for original equipment - installs like the factory part
  • Helps prevent catastrophic cooling system failure
  • Tank only - does not include cap or coolant level sensor

Regular inspection of your coolant expansion tank is essential for maintaining proper engine temperature. Replace immediately if you notice cracks, leaks, or damage to avoid overheating and engine damage. Early models without a coolant level sensor may require plug kit 1265000084 (sold separately).

OEM Part Numbers: 1265001549, A1265001549, A 126 500 15 49, 126-500-15-49, 126.500.15.49
