yea ya been there done that on page 2. lets assume that's not the problem especially if you dont flush system again. air can't stay in the system forever especially if there is coolant in the reservoir AND you bled it. did ya get that guage?

Right, as long as there is water in the RES then the air in the system will (for the most part) gather at the top of the radiator then when the engine cools it naturally sucks in water from the RES and it pushes out air when it warms because the fluid level rises when it gets hot.
I'm beginning to think you may have a problem with the hose or the pump. You're just going to have to get in there and rip it all apart and look.
I already replaced that huge heater hose on my car. Its a dealer item. It's an assembly of 2 hoses and a backet that holds it to the passenger fender well. Yes it was lovely to replace also.

bythe way, I just thought of something. Even if the heater hose is stopped up, I dont think that will make your engine get hot. Cuz I have known people to cap the hose off when their heater core sprung a leak. And they capped it because they didnt want to fix the heater core. So they plugged the line and kept water from going into the heater core. Its a 1970's trick. The sade tree mechanics always did crap like that..
So, I think even if the hose was blocked with "trash" it may keep the heater from working, because hot water is not getting through the hose, but it wont stop water from circulating in the engine or radiator. So, there is another reason why your engine is getting too hot..

by the way, how hot is too hot? This is the factory settings where the fan's turn on.
Camaro/Firebird/Corvette Stock Cooling Fan Temperatures:
Fan 1 on/off at: 227°F/218F°
Fan 2 on/off at: 235°F/228F°
- OPTIMIZED FOR stock 195° Thermostat
Fan 1 on/off at: 209°F/200°F
Fan 2 on/off at: 219°F/210°F
- OPTIMIZED FOR 180° Hypertech PowerStat
Fan 1 on/off at: 194°F/185°F
Fan 2 on/off at: 204°F/195°F
- OPTIMIZED FOR 160° Hypertech PowerStat
Fan 1 on/off at: 184°F/175°F
Fan 2 on/off at: 194°F/185°F

btw, jackign up the rear of the car would (if anything) make air rise BACK toward the heater core. You're suppose to have the front slightly elevated. BUt actually, I dont think its really all that critical because if the water is full, air will accumulate in the radiator. Then it gets pushed out as the engine warms, and then the system will suck water in as it cools. Natural purging of air pockets.

OK ONE FINAL Question... When your engine is stone cold and you warm it slowly with the cap off, does the water look like its foamy with a lot of air in it? Or can you see solid streams of water pushing out of the core of the radiator?
reason being is, if its all foamy... then you got a busted head gasket. And yes, with that much air in the system it will be hard to keep it cool..
So the question is, has your engine ever over heated? So much so that it warped the heads? You can check your oil to see if there is white creamy stuff on the dipstick. Or look inside the oil cap, to see if you can see any creamy looking stuff in the oil. This is not a fool proof way to tell if you have a leaking head gasket. Because it depends on where the gasket is broken. Water may not get in the oil. It may get in the cylinder. Then the cylinder burns it off when the engine starts. But this would only last so long because as it would get worse, more water would leak into the cylinder and burn off at startup.. But as more water leaks in, during crank up the engine will lock up. Because water does not compress. However air does compress which gives you a certain 10.5:1 compression ratio.
With a mildly broken head gasket, water can get burned off if its leaking into a cylinder and initially you won't know where it's going. But yet you have to fill it up often but you won't see it leaking anywhere..
With a massive hole in the gasket, water will be foamy at the top of the radiator. This is usually caused by overheating.

so what portion of the cooling system was it trapped and how did they know it was there?

well, a better question, how did they know it was there and where the air was... And once it was removed completely, how did they know it was gone..? Xray vision? don't think so. imagination..
but hey. I bet if you changed the fuel filter, it probably would have fixed it..

So Chad, if air is in the system, how do you know and where is it at?
WTF does a fuel filter have to do with it?

Why don't you take this knowledge of yours and put it to some good use in, as say, uh, a career since you have no life except for playing internet tech.
Fuel Filter fixes everything...
