    My 2008 Prius water pump is leaking so I went to change it and I notice there is no belt on it. I been looking online and every gen 2 has a belt for the water pump. Maybe some don’t?

    Yes, on the Gen 2, there should be a belt. The engine will not survive for very long without it, so if the engine still runs, you must have just lost it. Do not run the engine until you have a new belt installed.

    You will notice on your 2010 Gen 3, there is no belt as the water pump on that generation is electric.
