radiator capacity for 2002 Chevy S10

Hi folks:

Will need to be changing my coolent this weekend in the 2002 S10. It's a V6. I need to buy a drain tub to catch the fluid.

Question: It does not say in my owners manual. Can anyone tell me what the capacity is in the radiator? How much dex-cool anti freeze will I need to buy? How big of a drain pan?

thanks in advance!
