The unbranded ones are inferior and will break down quickly. They also cause the engine to vibrate because the electric motor does not seem to be compatible with the car. The cause of the vibration was unknown. Once I replace the cooling fan assembly with the original at Hyundai Service Centre, Puchong, this vibration was eliminated.
No issues to report except that the ATF hose broke which resulted in a breakdown due to the loss of all the auto fluid whilst on the road. Had to call for roadside assistance. After replacement of the hose and the refill of ATF, the car is back to running as normal.
Car mileage is at 285k km - engine still runs as new. Transmission is still original and shifts as new. NVH is good. Consumption remains the usual - not worse despite it being 15 years old.
