This is a lower radiator hose designed to connect the engine block to the radiator in Volvo excavators. It is constructed from durable, heat-resistant rubber to withstand engine operating temperatures and coolant pressure, ensuring a leak-free seal unlike a cracked or collapsed hose. Failure can manifest as visible coolant leaks, a persistent sweet smell of ethylene glycol, or engine overheating due to coolant loss.
Always verify with serial number before ordering.

Cross-reference part number with serial number before ordering to confirm fitment. Keep original parts until new ones are confirmed correct. Record part numbers replaced for future reference.
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 lower radiator hose is often a visible coolant leak at the connection points or along the hose body. If ignored, the hose can swell, crack further, or even burst, leading to rapid coolant loss and potential engine overheating. Continued operation with a compromised cooling system risks severe engine damage.
Ensure the engine is completely cool before attempting removal to avoid burns and coolant spillage. Do not overtighten the hose clamps, as this can damage the hose or the connection fittings.
Inspect the radiator, thermostat housing, and water pump for any signs of corrosion or leaks while replacing the hose.
