Default Overheating after Turbo-reinstall

Problem: Overheating
Experience: working on subi's for a few years now as a hobby (not a paid mechanic)
Story: I had a major oil leak from the oil line on the bottom of my VF39.. I installed it 6months ago, but somehow (perhaps the cold) it just recently started leaking oil last week.. Heavy (As in, a quart a day..all over the bottom of my car..whatever.) I removed the turbo, confirmed the problem, reinstalled the turbo properly (after much work in a freezing garage) and tightened everything down correctly. Refilled the oil, but not the coolant.. Forgot that.. But remembered about 2minutes of very very easy driving. Pulled over, happened to have a bottle of water in the car, so I added that (plenty, perhaps more then enough, but I figured it would just spray the excess out in that case) While driving to the auto parts store to pick up antifreeze and another quart of oil just in case, the car started overheating pretty bad. The car wasnt even warmed up enough for the heat to work (Or is this related to the problem?)

Again.. the fluids are all topped off, everything is reinstalled correctly and there are no pinched lines.

Ideas?
I've only come up with..thermostat.. clog in a line somewhere.. or maybe some other freak problem. I need to get this fixed by tonite, so this is semi urgent. Any takers?

Thanks
Scott

pretty much. i believe you are supposed to do it from the highest point, which would be the overflow tank coming off the turbo. basically open tank (with engine cold), let car heat up, continue to allow coolant to circulate and fill as needed.

i believe repeated revving opens up the system and allows any air that's trapped to be burped out, but my experience is in motorycles...i'm assuming that the cooling systems are pretty much identical.

I run the engine without the pressure cap until the thermostat opens. Usually one cycle gets rid of all the trapped air. You may get some overflow so either put a funnel at the top or have rags ready.

Use propper 50/50 mix for all coolant resevoirs.

1) Fill the coolant resevoir (plastic bottle) to the fill line (put cap on)
2) Fill the Turbo Coolant Reevoir (small metal right in front of turbo) (put cap on)
3) Start car and turn on heater (high)
4) Hold RPM's at 3000 for 10 minutes ( even if temp = H)
5) Turn engine off and leave key to ACC (keep heater on)
6) Let engine cool to "C"
7) Repeat steps 1-6 until no coolant is required to fill resevoirs

While replacing my turbo took 45 minutes to complete the process.

Like I said above DO NOT open radiator cap at anytime, to do so will negate everything you are trying to do.
Any other ways mentioned to burp the system on our cars are Shade Tree Mechanics.

Update:
Burped a ton of coolant into the system. It must have been low before.. doh.

Not overheating while driving, but sometimes it comes up while stopped and the heat isnt very hot anymore. Thermo stuck open?
