BTW... You car takes a CRAP ton of water/collant after a full flush/refill. So I take it your temp is always normal ?
When you say it takes a ton of coolant, how much do you mean? either i have a tiny little leak somewhere that doesnt puddle under the car (maybe only leaks while im driving) or this things is taking a ton of fluid.
i did a little reasearch, and it seems like it should not be taking this much, oh and as a side note, i dont know if this means anything, but my overflow tank hose keeps getting pushed up and partially out, i guess you would say, of the tank. It doesnt come all the way out, but it gets pushed up, and probably stops against the hood. kinda strange.

here is a vid i found, different year than mine, but would imagine they arent much different

I believe someone earlier posted 2 gallons.... But since you have aftermarket stuff, not so sure.

Have you looked in your oil yet?

Tell you what, start it with the radiator cap OFF and keep adding and squueze the top hose a few times, go underneath or have someone there with you to KEEP squeezing the bottom hose... Eventually you will get it burped correctly (but I think you have).

Are you adding just water or 50/50?

I would keep more coolant than water untill you find the leak... IF there even is one. It's easier to spot collant than water.

Heck, drive it around and fill it, then park it on your driveway and grab a 12pk with a few buddies untill you see where it's going.... <-- My answer to most things

hmm , i didnt think about the coolant being easier to see, but it makes sense. i just didnt want to keep dumping bottles of money into it lol. Yea i guess im gonna just have to do like you say drive-park-and look, and keep trying untill i find something. and beer pretty much goes with me every time i am out at the car fiddling with something

Ok, I've been watching this thread long enough. Here's what you need for the coolant issue. Fill into the upper reservoir quickly while at idle with a funnel that fits the opening tightly (cap on rad). keep the funnel continually full until it starts trying to spit coolant back up. When it does, rev it until it drinks the coolant down into the reservoir (yes it takes about 2 gallons) Cap tightly when it won't take any more. shut off engine, allow to cool. Test with pressure tester. Make sure both caps are good (137kpa on the rad, 108kpa on the reservoir)

Even a cheap one from harbor freight works. Checker (Oreilly's) or what ever parts stores often have those types of specialty tools to "lend". You just have to put down a refundable deposit. On the coolant reservoir (not the rad) pump it up to cap pressure (about 19psi) and see if the pressure holds steady, for 5-10 minutes. If it drops, pump it up more and find the leak. While under pressure, they will be easy to spot (or hear)

ok, as an update, i havent done anything else YET, but i do ahave a thermostat on order and i am going to check all the hoses when the rad is all drained, but one thing i did notice, testerday and today, is that when i park, i can hear the fan on to cool the radiator, so with the engine still running i check my overflow tank, and it has overflowed just a little, and it is full and bubbling. the water that comes out apperas to come right out of the lid, and the hose that goes into the top of the tank is always pushed up a bit. how strange. will update again after thermo install and hose check

HAHAAAAAAAAA!!! i didnt expect this... so my new therostat came in, and i drained the coolant out, pulled out the old thermo.... it was obviosly broken... and i reaaalllly dont think it would have done so on its own, so some idiot that had the car before me intentionally ripped the insides of it out, and still used the body/gasket to keep going. WOW, im wondering now what i got myself into when i bought this car with dumbass people like that doing any kind of work to it. well new thermostat it, will be testing it out good tomorrow, its already late now so not today. will keep udates coming

Well i think im F**ked , new thermostat is in, and it will only go about 2 miles before it wants to overheat. i didnt let it overheat, but it was on its way in a hurry. there are a lot of bubbles going into the overflow tank, where when i am driving only it will overflow. i cant get it to overflow at idle. sooo... looks like its gonna have to go to a shop to have some work done! yay oh and when i look closely at the exhaust, i can see some steam building up in the inside of the pipe wall. not much, not blasting it out by any means, but its there. SHIIIIIIIIIT !!!!!!!!!!! anybody kow about how much i should expect for a head gasket fix?

IF that's all it is, not much more than $500.
