I filled up the radiator when it was cold. Emptied the resistor compleatly. Drove it home 15miles. Just started to over heat when I got home. The next day I opened the radiator it was low on coolant. Checked the resivor it was full. So I poured what was in the resavor into the radiator and it filled it up perfectly.

So I know I'm not "losing" coolant it's still there just not in the right place. My thoughts bad radiator cap? Not letting pressure out and the coolant from the resivor back into the radiator?

Any more thoughts?

Go to a local auto parts store and get the loaner tool to check the cap. Make sure you got all the air bubbles out. I suggest raising the front of the car so the radiator is the highest point. Heat on high and fill as needed.

If the cap comes back good, bleed the system and you still lose coolant / overheat it will probably be what you don't want it to be. When was the water pump last done?
