in new coolant 50/50 mixture and idles fine the
heat works it drives good until maybe about 15

Try bleeding air from system like this remove cap from overflow tank fill with antifreeze to full mark leave cap off and start vehicle and let idle you will notice level in tank start to rise this is normal once thermostat starts to open level in tank will drop add more antifreeze to full mark then put cap back on.

I did that but the water never went down when i remove the cap and start the car it bubbled forever and water kept rising til i shut it off. Now when i used the bleeder screw it worked fine got all the air out drove fine for about 10 to 15 min then spat out water and over heated.
