Water Pump .. .to replace or not '06 90,000 miles

[Robin_Tursso]

My first timing belt was changed at 50,000 after it broke and blew the valves. I am now at 90,000 and the water pump needs replacing. I have at least 20000 more miles on this timing belt. It only costs $40 for the water pump and the GM replacement is lifetime warranty. So I would change it now, before it goes and you have to go into that encasement before you need to for the timing belt!!
