How long to replace water pump on Chevy Avalanche?

Replacing the water pump on a Chevy Avalanche typically takes around 3 to 5 hours, depending on the specific engine model and the mechanic's experience. The process involves draining the coolant, removing various components such as belts and hoses, and then installing the new pump. If you're doing it yourself, be sure to follow a detailed guide or service manual for your specific year and model to ensure a proper installation. Always remember to allow time for the coolant to fully drain and for the system to be refilled and bled afterward.
