543.02.0011 Expansion Tank, Radiator — MAN

The expansion tank serves a critical role in the cooling system of heavy commercial vehicles by managing coolant pressure and volume fluctuations. This high-strength component is designed to withstand extreme thermal cycles, ensuring the radiator system operates within safe parameters during long-haul operations.

543.02.0011 is the OE-equivalent of the MAN 81.26481-0074 expansion tank used in MAN TGL and TGM models. This part ensures precise fitment and maintains the pressure stability required for efficient engine cooling in heavy-duty transport environments.

For workshop technicians, this component requires careful inspection of the mounting points and hose connections during installation. Regular maintenance of the cooling system, including checking the expansion tank for any signs of structural fatigue or leaks, is essential to prevent overheating and maintain optimal vehicle uptime.

Engineered with heavy-duty grade materials, this part provides a reliable solution for fleet managers looking to maintain high-performance standards in their cooling systems.
