I have a 04 5.3 Avalanche, Im replacing the water pump, going to order from rock auto, but on their site it lists 2 ac delco water pumps, which one should I go with.
Also, what else should I replace while im there, hoses, belts, coolant tank, thermostat?

#1 - ACDELCO Part # 252845 {#19195104} Cast Iron Impeller; Does Not Include Mount Bolts; w/ Gaskets - $88.79
#2 - ACDELCO Part # 251714 {Click Info Link for Alternate/OEM Part Numbers251616, 251706, 88894290, 89018166} OE Design; Stamped Steel Impeller; Includes Mount Bolts - $192.79

 

PM your VIN, and I'll tell you exactly what pump you need and see if I can beat their price.

 

#2 seems more likely. I sell rebuilt ones for $100+

Also, the prices I quote you on thermostats, included the housing, not just the T-stat itself. Thanks again,and just let me know if we can get you fixed up!!
