      Its' possible, but you'll still naturally drop coolant thats in the hoses and the upper half of the system...

      it's not to hard and you will also drain whats in the overflow tank and here is a tip I learned when i did it on my car make sure the engine is cold Hot coolant really really burns

      Don't forget to open the coolant reservoir. This adds an alternate vent path and allows for quicker and more complete draining.

      i had my car overhead due to a bad waterpump. this melted my coolant flange to the point of replacement.
      when i replaced mine, i of course drained and flushed the coolant system.
      whatever you do, be sure to replace the coolant with the G12 coolant.
      if you dont, the coolant will "gel" and seize up the waterpump, leaving you with having to replace the pump again.
      also, if you need to replace the pump, look into a metal impellar, and not the cheap plastic ones that come OEM.
      i wish you all the best of luck
