Labor Time on Water Pump on 2004 Chevrolet Silverado 2500 HD

Does anyone have the details of how long the national labor time is for a water pump on this truck?

1.8 hours is what I see using Mitchell's labor times.

If this is a gas 6.0 V-8 it calls for 1.8 hours of time. I would recomend a coolant flush at the same time, if it hasn't been done recently. The coolant contains lubricants for the bearing in the new water pump. Not flushing the system will ensure premature failure in the new pump.
