2006 Scion xA Radiator Parts Q&A

• Q: How to inspect and clean the radiator on 2006 Scion xA?

  A: Measure the valve opening pressure on the radiator cap sub-assembly when performing inspection and cleaning of the radiator. The inspection of rubber packing numbers 1, 2 and 3 requires water cleaning with hand scouring when foreign objects or stains are detected. The inspection should show that parts 1, 2, or 3 have no deformities, cracks or swelling and that 3 and 4 are freely separate from each other. Before testing with the radiator cap machine apply engine coolant to 2 and 3 then operate the pump several times with the device oriented at 30 degrees or more above horizontal while observing maximum pressure. The radiator cap sub-assembly needs replacement when the maximum pressure measurement falls below the specified minimum standard value. On-vehicle cleaning requires checking fins for blockage by inspecting for leaves or dirt along with insects or inspecting the hose connections and ensuring the radiator and condenser are clean. The blockage removal process begins by washing the fins with water or using a steam cleaner but you must maintain distance to prevent damage from occurring. To straighten fins you should use both a screwdriver and pliers while refraining from pouring water toward electronic elements. After cleaning, the fins need to be dried using compressed air.
