Car is a 1990 turbo with the 7mgte. No leaks in any areas, but the car seems to be expelling all its coolant. The coolant is overflowing from the overflow tank as if there's too much pressure in the system. The overflow bottle is full and I have to refill the coolant once a day. Any ideas? Thanks!
Loosing coolant....Need help?

I would check the radiator cap and pressure test the coolant system for leaks. But, most of the time when it does this:
::bhg::
A NAPA block tester will confirm the presence of exhaust gas in the coolant system and a BHG.

Check for the presence of coolant in the oil...a lot of times you will see a brown emulisification in the oil cap with a BHG. In any case, stop driving the car...any coolant in the oil will trash the bearings in short order.
Hmm...... Bummer. I was hoping it would be smaller an issue. I was really thinkin an issue with pressure in the coolant system. It doesn't smoke and idles fine. Yesterday when I had it parked for a while it did it's thing with pumping coolant out the resevior and then the upper radiator hose seemed to shrink up like there was a vacuum. When I removed the radiator cap it expanded back to normal size.
A cap tester is the best way. You could just buy a new cap as well.
I would still have the system pressure tested...pretty sure you can get a loaner at AutoZone or take it to a radiator shop.

It means the cap's vacuum valve isn't sealing although the pressure valve portion or it's seal would also have to fail to allow coolant purging. Do as jdub suggested. Also check both the rad neck upper and lower sealing surfaces. Since you didn't provide enough info for a more thorough diagnosis it's still sort of a crap shoot though...
A BHG is a issue of pressure, as in the exhaust gasses will pressurize your coolant system(coolant overflowing), but do as the elders say, you may have a chance yet:icon_bigg
Ok so got another radiator cap(had it layin around and remember it being good). Same issue. Also when I started it I sat for a few waiting for it to warm up and oculds hear sloshing sounds from the dash. When I gave it gas it seemed to respond accordingly by sounding like it was now rushing water. Seems perhaps I have air pockets in the coolant? Hoping still it's not a BHG. Doesn't seem to be coolant in the oil when I checked the dipstick.
What else should I look for?

Did you check the oil cap like I suggested?
To confirm exhaust gas in the cooling system you will need a NAPA block tester. (like I already said)

Sorry forgot to respond to that. Didn't notice any emulisification in the oil cap. Seemed to be just oil and no coolant. Also haven't been to a Napa. They all close at like 5pm here and I got off at 6. I'll likely not be able to go till Tuesday.
Well all my wishing and wanting was in vain. Looks like BHG is name of the game. The engine has over 200k miles so it's really on it's last leg anyways. I think it's gonna be just rebuild time since I got it all apart anyways.
Thanks everyone for all your help!!
