    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.

    How do I find the water pump on my car?
    Community Answer
    Open the hood, follow the belt, and it should be underneath the main fan right behind the radiator.

  • 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.
