A shotgun approach to repairs can really rack up the bills.
If your symptoms are loss of water and you have replaced the thermostat, you more than likely have an issue with steam. And that steam more than often comes from a bad head gasket. Most head gasket gasket failures seem to be confined to the water side initially, but let it go on bigger damage will occur.
You can buy a litmus test strip to dunk in the coolant. It will indicate if there are exhaust residuals in the water and thus a gasket failure.
However it may just be something simple, given that you have just about replaced everything:
have you given the radiator a good hosing inside and out?
is the radiator fan running when it should be?

You should take it to a rad shop and get the whole cooling system cleaned and flushed,then pressure tested to eliminate it before goig any furter because an y other cause of overheating is going to cost you a bundle.

first check to make sure the cooling system is not air bound,takes a while to bleed off the air,try this and get back to me Thanks Ray

The bright light fitting is the same as the dim so take it apart fist to see how the cover screws off/on and the light comes out. Both the cover and the bulb are removed by a standard twist to the counterclockwise and replaced by a twist to the clockwise. Now to the dim light. You have to release the entire light assembly before you can remove the screw-on cover to reach the light. On the rear edge of the light unit closest to the engine is a white locking tab. Pull that tab up just to the point where it releases…pull too far and it locks again. Next, locate the other locking bracket which is a metal bracket in the center-rear of the light assembly. This bracket is held down by a screw. Remove the screw with a 10mm wrench. Lift the bracket just like you did the white bracket. You should now be able to pull (or pry) the entire light unit forward a little. Depending on the size of your hands this might be enough. If not, then you need to release the plastic bumper assembly to give you a little more space. This is done by removing two expansion locking pins, one that holds the little plastic strip down between the bright and dim lights and one that is located inside a rubber bumper on the engine side of the light unit. To remove these locking pins, pull or pry up the little tab in the center of the pin just like you were pulling a nail by the head. That should give you more space.

cylinder head gaskets, or cracked cylinder heads, this is a bad problem with the 3400 engine, so bad that we keep a set of heads in stock at the shop.....SORRY
