  1. Confirm that the water pump is nonoperational by examining the functionality of the bearings by manually jostling the fan blade. [1]
    • This applies to fan operated cooling systems. The fan bearing should remain firmly seated if it is not in need of repair.
    • The shaft should remain tight if it is working properly.

    • A few drops of water should sweat from the vent hole over a long period of time, but a ruined seal will cause excessive overflow.

    How do I know if my engine block got cracked?
    Community Answer
    Open the radiator cap and stick your finger in it when the engine is cold. If there is oil on your finger, this is one sign of a cracked block. Your engine will lose compression and overheat, this is another sign. Your vehicle might also lose or burn a lot of oil.

  • Question
    How important is a temperature sensor?
    Community Answer
    Very important, because without it the cooling fan cannot start at the right time, and also the car's main computer needs to know it for the right fuel air mixture.
