New water pump/T stat questions. My water pump seems to be starting to drip a little, so before it gets any worse I wanna swap it out. It is the stock 60K pump. Now, a few questions. What pump should I get? A more costly GM one, or will a new Advance Auto Parts one with a warranty be just as good? Also, I have a 160 T stat. I have been told this will NOT fit on the new water pump and I will have to buy a newer 160 T stat? Finally, and tips or tricks to get the bubbles out when I am done? Any advise will be great as I want to do this really soon.
Thanks!
Thanks!

I don't know about the 160* t-stat. I kept the stock one when I changed my pump. I don't believe it, myself. The replacement pump will be the same as the old one, what fits one should fit the other.
I got a new water pump from the parts store rather than a rebuilt. I don't figure to need one real soon and I believe it to be a fair choice. I don't pay dealership prices unless it's on something I can't get anywhere else or the price diff isn't very big.
To purge the system of air:
-Fill the radiator, start the motor.
-increase idle and pour in more coolant as the level goes down.
-do this until the t-stat opens up. Continue. Watch the bubbles slow.
-when you about have it, shut off your motor and put the cap on.
-fill your overflow bottle about 3/4 full. Drive normally for a while, keeping an eye on the bottle. Refill to 3/4 every time you let it cool off. Run the heater wide open several times.
-When it stops needing refilled, you're done. Could take up to 150 miles.
-Check everything you removed/replaced while doing all this, and for a week or two after.

I got a new pump from gmpartsdirect.com You can shoot them an e-mail and they'll let you know the part number. The pump came with gasket and the thermostat attached. Go to ls1howto.com for pump removal/installation instructions.
