Gen 2 Prius taxi came in with a loud whining noise. We concluded that it was the water pump. We followed where the sound was coming from and we also noticed pink coolant all over the area. We first drained the coolant then we remove and replaced the water pump.

| All the pink coolant confirms a leak coming from the water pump. |

| Fixed... New water pump. |

Bad Water pump.
After installing the water pump. Before you start the car... connect Techstream and manually activate the water pump with the computer. Do this about two times so coolant can run through before you start the car. After starting the car use a pedal depressor on the accelerator. As the engine runs you add coolant and make sure that the thermostat opens and the fans run about two or three times. Erase any codes left in the car. |
