without tools, I jack up the rear of the car, flip the tab on the coolant tank into the upright position, open the cap, fill the tank, start the car, run it at 2500 or so rpm and keep topping off the water as it burps. Makes a little bit of a mess but when I've had to do it at the track there is no interior in the trunk and we're only using water so it isn't that big of a deal. Takes 10 minutes or so until the fluid level stabilizes. Be sure to check it again and top off as needed after its run and cooled.
