This lower water hose connects the engine's water pump to the radiator, facilitating coolant circulation for engine temperature regulation. It is constructed from durable, heat-resistant rubber compounds to withstand constant exposure to hot coolant and engine vibrations, unlike a brittle or cracked old hose. Operators may notice coolant leaks under the machine, a rising temperature gauge, or steam emanating from the engine compartment when this hose fails.

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 failure is often a visible coolant leak beneath the machine, particularly around the engine area. If ignored, the leak can worsen, leading to a gradual or rapid loss of coolant and potential engine overheating. Continued operation with a compromised cooling system risks severe engine damage due to excessive heat.
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 ports.
Inspect the radiator and water pump for leaks or bearing play when replacing the lower water hose.
