what brand thermostat did you use?

If its autozone, pull that shit out and throw it away and buy a real OEM one.

What kinda fans are you using? E-Fans or Clutch?

also check for obstructions infront of your radiator.

Sounds like you had air bubbles in the system. Try jacking the front end with the rad cap off and topping off the coolant and let the motor run to temp. Should help get the bubbles out.

Could of been the rad cap, but u let it run with it off and i think it helped bleed the system a little. Could of been when you changed the thremo and got air in the system.
