Based on industry averages you can expect to pay between $6.79 and $58.99 for a Mercedes expansion tank cap.
The expansion tank of your Mercedes-Benz is actually a plastic bottle that carries the coolant required for your engine's proper operation. The expansion tank cap's job is to adjust the internal pressure in the cooling circuit. Expansion tank caps have a 2-way valve and a pressure relief valve. As the coolant heats, the cap regulates the pressure and permits coolant to flow back into the radiator as the engine cools.
Like all other parts, the Mercedes expansion tank cap will need to be replaced over time. Here are the most prevalent signs of a faulty expansion tank cap that you should be aware of:
- Overheating engine
- Leaking coolant
- Burst or collapsed radiator hose
- Reservoir tank overflowing
