my 1999 acura TL, 3.2L v6 temp gauge says its running hot but I have no heat? on 1999 Acura TL

I have already found the actual radiator cap to be faulty, the whole spring mech was missing and it was just dumping coolant to the overflow tank. so I replaced that and I also replaced the thermostat. is there an coolant bleeder valve that i'm not seeing or is there another issue I should be considering?

replace your thermostat..follow the shop manual for your car when doing so
thermostat has been replaced. did it this morning. it was really easy. still no difference. the car seems to get hot fast but I have no heat. also, it seems that the cooling fans only turn on if
a) a/c is on.
or
b) right after I turn the car OFF.
I don't understand what the problem is. is there still air in the system? I feel like I got it all out but... Did the heater core go? Maybe there is an obstruction somewhere. I NEED HELP!!! Please email after 500pm unex3007@yahoo.com need tis car fixed asap! Help!
