Do you need to change the water pump when you change a timing belt on a 2006 subaru impreza?

Yes, it's generally recommended to change the water pump when replacing the timing belt on a 2006 Subaru Impreza. Since the water pump is often driven by the timing belt, replacing it at the same time can prevent future labor costs and potential issues, as the water pump can wear out over time. Additionally, this proactive approach helps ensure the longevity and reliability of the engine.
