* Accessibility: Some vehicles have easier access to the water pump than others. Unexpected difficulties accessing the pump could add time.
* Condition of the vehicle: Rust, seized bolts, or other issues can significantly increase the repair time.
* Additional repairs: If other components need to be replaced while the water pump is being accessed (e.g., belts, hoses), the time will increase.
