183-8119 Upper Hose — Cat 320C

This is an upper radiator hose that connects the engine to the radiator, facilitating the circulation of coolant for temperature regulation. It is constructed from durable, heat-resistant materials to withstand the high temperatures and pressures of the cooling system, unlike a cracked or swollen hose. Operators may observe coolant leaks, a rising temperature gauge, or steam escaping from the engine compartment if the hose fails.

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

Initial signs of a failing upper hose include visible cracks, swelling, or a persistent coolant smell. If left unaddressed, a weakened hose can rupture under pressure, leading to a rapid loss of coolant and engine overheating. This can cause severe engine damage due to excessive heat.

Installation Tip

Ensure the connection surfaces on the engine and radiator are clean and free of old gasket material or corrosion before installing the new hose. Do not use excessive force when sliding the hose onto the fittings, as this can damage the hose or the connection point.

Service Note

Inspect the lower radiator hose, thermostat, and water pump for signs of wear or leaks when replacing the upper hose.
