OM366 Overflow Bottle 

Maintain proper cooling system performance and protect your engine with this Overflow Bottle designed to suit OM366 Unimog models. This expansion tank plays a vital role in managing coolant expansion, system pressure, and fluid recovery during operation.

When servicing the cooling system, you should always inspect and replace ageing plastic components. Over time, heat cycles, vibration, and harsh working conditions cause overflow bottles to become brittle, cracked, or discoloured. As a result, coolant leaks and pressure loss can occur, which may quickly lead to overheating and expensive engine damage. By installing a new overflow bottle during maintenance, you actively protect your engine and improve long-term reliability.

Designed for durability and consistent performance. In addition, its direct-fit design allows straightforward installation and dependable sealing. Consequently, your Unimog benefits from stable coolant levels, improved system efficiency, and reduced risk of cooling system failure. Whether you are refreshing your cooling system or replacing a damaged tank, this overflow bottle remains a critical component that should never be overlooked.
