This upper radiator hose connects the engine's cylinder head to the radiator, facilitating coolant circulation for engine temperature regulation. It is constructed from reinforced EPDM rubber to withstand high temperatures and pressures, unlike a brittle or cracked old hose. A failing hose may cause the engine to overheat, indicated by a rising temperature gauge or steam escaping from the engine bay.

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 upper radiator hose is often visible cracking, swelling, or a soft, spongy feel. If ignored, the hose can rupture, leading to a rapid loss of coolant and potential engine overheating. Continued operation with a coolant leak risks severe engine damage due to excessive heat.
Ensure the cooling system is completely cool before attempting removal to avoid burns. Do not overtighten the hose clamps, as this can damage the hose or the connection points.
Inspect the lower radiator hose, thermostat, and water pump for signs of wear or leakage when replacing the upper radiator hose.
