1993 Camry XLE....Needs a lot of help!!!

Okay I have a 1993 Camry XLE.....I have now had it for one year. It is a piece of crap. I have had so many problems with it, and the newest one has to do with my radiator. Okay....I dont drive the car a whole lot. But every morning before I start the car and go....I have to check the radiator and the Engine Coolant container to make sure there is water in there. The water container is always empty now.....and whenever I go to open the radiator....there is this white crap floating around, and stuck to the sides of the radiator (inside)....weird......You know how there are sort of two places where you can open the radiator up....(i think one your not really supposed to open, but I had to).....well anyways.....the one closest to the front of the hood.....whenever I open that one.....it is always fulll.....and is always full of antifreeze. Yet I have not had any antifreeze in a week or so, so I have just been putting water in there. But for some reason the antifreeze always seems to stay up there. Hope I didnt lose anyone here......I have blown in the hoses to make sure it is not clogged, and it seems to flow okay.......
I dont know what o do with the car.....Im so sick of always having to fill it with water......There is not leak in the radiator either......not that I am aware of.....I have not seen it leaking anywhere......
HOW DO I FLUSH MY RADIATOR? TO make sure there is nothing cloggin it at all? DO I ahve to get some kind of kit or something?
Please help.....There are so many more problems, but I dont have time or room to explain them all......

The best way to find out if there is a coolant leak is to have the cooling system pressure tested.The cooling system is vital to the engine,so it's better to address right away.

Had same problem on a 92 SLE V6. Ended up just buying another Radiator from Radiator.com the toyo dealer want 400 but i think with shipping and everyting it was about 95 through radiator.com. I tore the other radiator apart to see what the problem was and it was filled with rust.This one is funny but it worked I flushed mine by taking off both hoses except the top one and tape a water hose to it and turned it on and left idle for about ten minutes or sooooo. Cleaned right out.
