2004 trailblazer How much coolant will come out of water pump if you do not drain it?

I assume you want to change out the water pump and would like to know if you can do it without draining the radiator. You will lose approximately all the coolant in the radiator reservoir when you remove the radiator hose from the water pump. If the coolant is in good, clean condition, it might be wise to drain the radiator into a container and re-use the coolant.
