weird problem after a/c compressor R/R

[bad_tx_z28]

ok guys, i have a weird problem. Today i removed and replaced my a/c compressor with a new used one. The system has not yet been charged. Here is the problem. I refilled the radiator and started the car, waited for the t-stat to open up for circulation and put some more coolant in the Rad. I then put the cap on and continued to let it idle. Temps were ok and everything seemed okay. Then i heard water pouring. Looked in the engine bay and the coolant resivour was spewing. I opened the cap, there was no pressure, looked inside and could see no water. Also i noticed when i revved the engine a little bit the top coolant hose constricted. What the hell is going on? any help is much apreciated

thats wierd you probably have air on the system.

i thought that too...i couldn't get my bleed screw loose, so i just left the cap off...up buch of bubbles came up. but when it was done bubbling i but the cap back on and the same prob.

Sounds like you got some major air pockets, the bleed screws are important.

Reverse flow = your going to need to drive it to even get all the air out. Bleed it as best you can, keep it from overheating and then take it for a ride to get the rest out.

^^i agree with fixxer, you going to have to take the bleed screw out.

i did take it for a lil drive...it didnt overheat any, but the overflow resivoir did overflow..lol. Like i said i tried to loosen the bleeder screw, but it was froze. I put some PB blaster on it and im letting it sit over night.
