374-0171-3740171 Water Tank Radiator 374 0171 — Cat 305 306

This water tank, also known as a radiator tank, is a crucial part of the engine's cooling system, housing the coolant and facilitating heat exchange. It is constructed to meet OEM specifications for durability and thermal performance, ensuring efficient heat dissipation unlike a cracked or corroded tank that can lead to leaks. Operators might notice coolant levels dropping unexpectedly, visible coolant leaks around the radiator, or the engine running hotter than normal when this tank is compromised.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The most immediate sign of a failing radiator water tank is a visible coolant leak, often seen as puddles under the machine or staining on the radiator core. If the leak is not addressed, the coolant level will drop, leading to inadequate cooling and potential engine overheating. Continued operation with a leaking tank risks severe engine damage from sustained high temperatures.

Installation Tip

Ensure that the sealing surfaces between the tank and the radiator core are perfectly clean and free of any debris or old gasket material before assembly. Do not overtighten the clamps or bolts securing the tank, as this can crack the plastic or deform the seal.

Service Note

When replacing the radiator water tank, it is recommended to inspect the radiator core for damage or blockage and check the condition of the radiator cap.
