This radiator tank is designed to effectively dissipate heat generated by the engine, ensuring optimal operating temperatures for efficient and reliable performance.

Measuring 35.2 inches long, 23.6 inches wide, and 12.4 inches high, this heavy-duty radiator tank is constructed from high-strength materials to withstand the rigors of commercial transportation.

The tank is equipped with a sight glass, which allows the driver to easily check the coolant level without having to open the radiator cap. The tank also includes a pressure cap with a built-in temperature gauge, providing the driver with crucial information on the engine's operating temperature.

The tank's inlet and outlet connections are located at the rear of the tank, allowing for easy access during service. The inlet and outlet ports are designed to accommodate standard 19mm radiator hoses. The tank's design also includes a drain plug located at the bottom for easy draining and maintenance.

The Freightliner 870849 Century 120 Radiator Tank is engineered to meet or exceed the rigorous standards of the commercial transportation industry.

The Freightliner 870849 Century 120 radiator tank is a component frequently used in heavy-duty commercial vehicles. Here are some potential pros and cons when considering purchasing this radiator tank:

1. Durability: Freightliner is a well-known brand in the commercial vehicle industry, and their components, including the radiator tank, are built to withstand the rigors of heavy use.

2. Capacity: The Century 120 radiator tank has a large 120-gallon capacity, which can help ensure adequate cooling for heavy-duty applications.

3. Easy Installation: The tank is designed to be a direct replacement for other Freightliner models, making installation relatively straightforward for experienced mechanics.

1. Price: The Freightliner 870849 Century 120 radiator tank can be quite expensive compared to aftermarket alternatives or smaller capacity OEM tanks.

2. Weight: With a large 120-gallon capacity, this tank is also quite heavy, which can add to the overall weight of the vehicle and increase fuel consumption.

3. Availability: Depending on the specific application and location, it may be challenging to find a local supplier or parts dealer that carries this particular tank, which could lead to longer downtimes for vehicle repairs.

In conclusion, the Freightliner 870849 Century 120 radiator tank offers several advantages, including durability and large capacity, but it also comes with some disadvantages, such as a high price point, weight, and potential availability issues.

For fleets or owner-operators that require heavy-duty cooling systems and are willing to invest in a high-quality, reliable component, the Freightliner 870849 Century 120 radiator tank could be an excellent choice.
