Once all that fresh watrer stopped dripping I buttoned it all back together, added 1 gallon of Zerex G-05 (gives me a 40% mix) and the rest water. My 602 vents air pockets to the reservoir so I kept an eye on it for a 100 mile or so.

This is probably the single most important thing to do !!

Once you have filled it & started it & checked for leaks, take it for a run around the block (a mile or so) & check for leaks & the level of the coolant.
Then after you drive the car for a regular short run, check it again.
When you next fill with fuel, check it again.
If at any point in the not to distant future, the temp goes up unexpectedly or the motor gives other signs of being hot, check the coolant level & for leaks.
Its important to make sure that you have the heater operating when the car is first started to make sure it is filled with coolant.
