1415722 Water Tank Radiator — Cat 320B

This is the radiator top tank, a critical component of the engine's cooling system that holds and distributes coolant. It is manufactured to withstand high temperatures and pressures, unlike a cracked or corroded original tank that may leak. Observable signs of a failing radiator tank include visible coolant leaks around the tank seams, white or green crusty deposits, and a persistent drop in coolant level.

Installation & Application Notes

Flush cooling system with distilled water before refilling. Use pre-mixed coolant — never plain water, which causes corrosion. Pressure-test system after any cooling repair. Check thermostat by immersing in hot water — should open at rated temperature.

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

Failure Symptoms

Visible coolant leaks, often accompanied by a sweet smell, are the first indication of a failing radiator tank. Continued operation can lead to a significant loss of coolant, increasing the risk of engine overheating. Prolonged operation with a leaking tank can cause severe engine damage due to insufficient cooling.

Installation Tip

Thoroughly clean the radiator core and tank mating surfaces to ensure a proper seal, removing any old gasket material or corrosion. Do not use excessive sealant, as it can impede coolant flow or contaminate the system.

Service Note

Inspect the radiator hoses and thermostat for signs of wear or malfunction when replacing the radiator top tank.
