The utility model discloses an automobile engine water pump capable of judging true or false water leak. A water storage tank is arranged at a gap between the water seal of a water pump casing and a bearing chamber and is communicated with a water seal hole. In case of false water leak, the leakage water entering the water seal hole is less, and the leakage water is stored in the water storage tank and evaporated along with the increase of the temperature of the water pump; when the water seal is worn out and loses the function to cause true water leak, the leakage water is stored in the water storage tank and flows out of the water pump from an overflow hole at the upper part of the water storage tank. The true or false water leak of the water pump can be accurately judged by observing whether there is water flowing out from the overflow hole, so that the loss caused by false judgment is avoided, the safety is enhanced, and the entire water leak test is visual, accurate and easy for operation.
