Replaced the alternator on my 06 Z i had to take out the radiator fan which required me to remove the upper radiator hose which caused coolant to come out, obviously. got everything back together and the car is now over heating after i put in coolant. let the car run for 30 minutes and let it bleed but it started boiling out the radiator but i didn't use the bleeder valve because i just learned about it. Oil is not milky so i don't believe it is a blown head gasket. what could i be. also the heater does not work! thank you!

 

You can't just randomly bleed the 350z cooling system. Consult the factory service manual, and this thread:

Shortcuts, or just general lack of understanding of this issue, will result in permanent engine damage.
