I have a 94 GSR and I have noticed that the radiator keeps pushing the coolant into the resivior and filling it up. I have replaced the radiator, thermostat, and bled the radiator twice. I have also done a pressure test and there were no leaks. I think it could be the head gasket but I haven't seen and smoke and it hasn't overheated. I pulled the radiator cap off and no coolant was in it. I also replaced the radiator cap. I cannot figure out the problem and I was wondering if anyone has had a similar problem and could help me out. I just get some advice before i pull the head.

TIA

 

unless youre seeing bubbles or oil in the coolant, its not the headgasket. are you positively sure theres no leak? maybe your radiator needs to be flushed out. you might want to make sure there is pressure in the coolant lines.
