before you go replacing all these parts and hot wiring everything get a tap and die set and chase and re-thread the bolt hole you stripped out, then check and make sure the radiator isnt stopped up at all, if the car has sat for while before recently this could be a big source of your problem, mine did the same thing and after hours and hours of thermostats and hoses it was the radiator the whole time, also check the coolant overflow since it is under the battery, battery acid melts plastic, and mine had a huge hole in it from this, if the radiator is open and the overflow is sealed, then re-post and we can help.....by the way get the fans working, grab a test light from autozone or whoever and check the relays and the fan motor out with that, if all is well at the motor then its a relay....
