Coolant not flowing I'm having some problems and trying to figure themout. Everything was working fine. I decided to pull the radiator cause I was having some slight cooling issues. Wasn't overheating, but would get really warm if I was in stop and go traffic with the A/C on. After evaluating everything and talking with a guy I work with that's pretty knowledgeable himself; I ran some things by him and he suggested it was the radiator. The pump was pumping and coolant was flowing so that pretty much eliminated the pump and thermostat, so I decided to replace the radiator.
Well the replacement was the wrong one, so I stuck the old one back in, but before I did that I ran water through it forwards and reverse several times to just make sure it was flowing. That checked out good. Now, after everything was installed, no coolant is moving, the car almost overheated on me. Upper radiator hose was cold which suggests the pump isn't pumping. Bought a new water pump. Still the same thing. Stuck in a new thermostat. Still the same. I'm stumped now. It all worked before this and now nothing.
I'm gonna go ahead and order the right radiator and go from there unless someone else has any suggestions. And yes all the hoses are in the right locations. Really don't think you can mess that up. The only other thing that I can think of right now is that maybe with the cap off it's not building enough pressure to help open the stat, but I was always under the impression that it opened due to temp not pressure, but maybe it takes both. Any suggestions will be appreciated. Thanks in advance.

You probably had a stuck t-stat.
If your getting hot with the A/C on....you should pull the condensor out and have it professionally cleaned at a radiator shop.
