I have changed the thermistat, checked to make sure i have no head gasket leak, changed the radiator and put a new radiator cap on and bypassed the heater core and my car will still overheat and push coolant into the over flow tank and cause it to over heat other than that i won't leak any coolant.
Does anyone have an idea what could be causing this?

I have a 96 and was also having the same problem, I've now replaced most of the cooling system, but I do believe that the original problem was the fact that the lower hoses were a bit spongy and were collapsing, not allowing circulation and causing overheating. Change all of the hoses, and if that isn't it, have your sensors checked. Good luck, it's a tremendously fun car, I love mine!!!

When you replaced the radiator and bypassed the heater core, did you bleed the system? If not, that could be your problem, as air prevents the water from circulating through all parts of the engine. Additionaly, because air displaces areas that water should occupy, there is less water in the system. This will cause the smaller water mass to reach higher temperatures sooner.
If, after the bleeding the system, you still have the overheating problem, inspect the water pump. You should not have to bypass the heater core to prevent overheating.

Have you ever used stop-leak in the radiator? I had an older car with the same problem and it ended up being caused by a blockage in the lines caused by a build-up of the little rubber-like ball stop-leak, the kind that melts to plug holes

check all your fuses for ALL of your fans if ythe fuses are blown then most ikely your motor has ceased up check to see that the motors are getting electricity with a meter is a good idea too you could also have clogged lines too but check your voltage and fuses first and either take a stick or your finger and try to spin the fan if it spins it's not seized up if it fdoes but not very easily that could be blowing your fuses or burning out your motors.

Are your cooling fans coming on?
Did you check the cooling fan motors?
Check the cooling fan relay?
Check the Temperature Sensor?
Make sure the water pump is working?
Only things left that I can think of.
Does it overheat on the freeway? When you're stopped?

sounds like a definite case of clogged lines
