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?

Where is the thermostat in a dodge dakota 1992 located? Flushed it yesterday still just have heat blowinf ti side vents rather cool windsheild defrost. Maybe there is another problem?
SOURCE: the rear a/c on my 1996 gmc suburban is blowing
the problem is in the rear expansion valve. this valve is located at the rear evaporator core. i am assuming the freon level has been checked and is ok. this is a common problem with these vehicles. hope this helps!!
SOURCE: i have a 91 toyota truck and the heater dont work
1. Check you antifreeze to make sure it is up to the correct level. Low coolant doesn't make it's way to the heater core thus no heat.
2. IF that don't work, replace your thermostat and one of those things 9 times out of 10 will fix your problem and they're cheap too.
