Mounted directly onto viscous fan coupling hub behind radiator, this multi‑blade plastic impeller generates forced airflow flowing through radiator fins. Unlike electronic fans, this mechanical fan spins alongside crankshaft power output, delivering consistent cooling airflow especially at low vehicle speed where natural wind flow stays insufficient for heavy‑load off‑road driving.
Long‑term engine‑bay high‑heat exposure plus repeated mechanical shock will degrade original plastic material. You will run into typical failure conditions: partial fan‑blade cracking, fragments flying apart under engine revving, insufficient air flow leads to continuous coolant‑temperature rise during crawling or trailer‑pulling. Many workshops spend time replacing thermostat and radiator before noticing broken fan blade as real failure origin.
This replacement fan blade replicates factory‑spec hub bore size, blade curvature and overall outer diameter for Patrol Y60 GQ. Reinforced modified plastic formulation improves thermal aging resistance. During installation, technicians only need to bolt it onto original viscous coupling assembly, no extra drilling or reshaping required.
