High-Quality Mercedes S350 2020 Coolant Expansion Tank – Authentic MAHLE/GERMANY

This genuine MAHLE/GERMANY-manufactured component offers superior quality and reliability at the best price. It’s brand new and ready for immediate installation.

The Mercedes S350’s supplemental coolant reservoir is a crucial part of the vehicle’s cooling system. This plastic container acts as a pressure-relief chamber, accommodating excess coolant when the engine is operating at high temperatures. The system’s pressure cap functions similarly to a pressure valve in a pressure cooker; coolant flows into the reservoir under pressure, then returns to the radiator as the system cools. This typically leaves approximately one-third of the coolant in the reservoir.

The reservoir’s transparent construction allows for easy coolant level monitoring. A secure cap with a rubber seal prevents leaks. The unit includes integrated level indicators and connecting hoses for seamless integration into the existing cooling system. A properly functioning auxiliary coolant reservoir ensures optimal engine temperature management, enhancing engine longevity and overall vehicle performance. Signs that replacement may be needed include cracks, leaks, contaminated coolant, or persistently low coolant levels. Addressing these issues promptly promotes reliable vehicle operation.
