I replaced the thermostat,the car still over heats and the heater still does'nt blow heat. the sticker under the hood says there is a special way to add coolant is there? I dont have a services manual...HELP!!!!!

It's probably air bound. In my 51 years of working on cars I've never heard of a special way to add coolant.
I just put some in the radiator or the container, start the engine, wait for the thermostat to open,then fill it, leave the cap off so it won't get air bound while it's running.
If there is a bleeder valve on top of the thermostat housing, open that until there is a steady stream of coolant coming out, then close it and refill system.
If it still over heats, you might have a clogged radiator.
