2006 Scion xB Radiator Parts Q&A

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

  A: You must verify the radiator cap sub-assembly through valve opening pressure measurement when checking and cleaning the radiator. Clean rubber packing 1, 2 and 3 by washing them with water followed by a manual scour. Ensure rubber packing in positions 1, 2, or 3 exhibits no deformity, cracking or swelling and parts 3 and 4 are not fused together. Engine coolant needs application to rubber packing 2 and 3 prior to using a radiator cap tester. The cap tester should be pumped multiple times in a position above horizontal at 30° or higher to identify the maximum pressure performance but the cap's inability to reach this point does not indicate failure. The replacement of a radiator cap sub-assembly becomes necessary when maximum pressure readings fall short of the minimum standard values. Vehicle cleaning should focus on clearing radiator and condenser blockages while ensuring these components remain free from leaves and dirt and insects together with cleaning the hose connections. Water or a sterile steam cleaner can be used to wash blocked fins when using proper standard distance during injection to prevent fin damage. Use a screwdriver or pliers to adjust bent fins and avoid spraying water toward electronic elements. Dry the fins with compressed air as the last step.
