I think you need to start at the beginning again in the repair. 1 )Empty all the antifreeze from the car. Remove the thermostat and make sure it was installed in the correct position. I would just purchase a new at this point. 3) flush the entire system with a good system flush two times. Install all the parts and refill the system, MAKE SURTE YOU BLEED THE AIR OUT.

Check your spark plugs. A very clean plug or one covered with a white residue indicates a blown head gasket. A blown gasket will push compression into your cooling system and blow out your coolant.
