However, several factors can influence this time:
* Mechanic's experience: A more experienced mechanic will likely be faster.
* Access issues: If there are any unusual difficulties accessing the water pump due to rust, seized bolts, or other mechanical issues, the job will take longer.
* Needed repairs: If other related components need attention (e.g., a worn belt, thermostat, or hoses), this will add to the overall time.
* Shop vs. DIY: A shop might take longer due to scheduling and other factors, while a DIYer might take considerably longer due to lack of experience.
Therefore, 3-5 hours is a reasonable estimate, but it's always best to check with your local mechanic for a more accurate quote based on their experience and assessment of your specific vehicle.
