This is an upper radiator hose designed to circulate coolant within the engine cooling system of specific Volvo excavators. It is constructed from durable, heat-resistant rubber to withstand high temperatures and pressures, ensuring a longer service life than a cracked or collapsed hose. A failing hose may cause the engine to overheat, leading to visible coolant leaks or a noticeable loss of engine power.
Always verify with serial number before ordering.

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.
The first sign of a failing upper radiator hose is often a visible leak or a soft, spongy feel. If ignored, the hose can burst under pressure, leading to rapid coolant loss and severe engine overheating. Continued operation with a compromised cooling system risks significant engine damage.
Ensure the engine is completely cool before attempting removal to avoid burns from residual coolant. Do not overtighten the hose clamps, as this can damage the hose or the connection points.
Inspect the thermostat and water pump for proper operation when replacing the upper radiator hose.
