My car keeps overheating but the radiator and backup compartment for coolant are completely full, it smells like something is burning and every once in a while the power steering goes out, I cant even drive the car 2 miles without it completely overheating, even with the heater on it overheats, I don't know if its the thermostat or a more serious problem. I really don't have the money to pay for a diagnostic, if its just a hose or belt or thermostat I can afford that but I can't afford anything crazy. Any help would be appreciated.

Before I say anything, I need you to check and make sure the serp belt is tight. It sounds like the belt is loose allowing the PS to not work properly. If it is loose, the water pump may not be turning fast enough.

Check that and let me know what you find.

That is what I thought. The burned spot is most likely from trying to turn things but instead slipping.

Your vehicle has an automatic belt tensioner. It needs to be replaced. I have attached a diagram of the belt system on your vehicle. The first pics are of a timing belt. That isn't what you need, but if you page down, you will see diagrams of the serpentine belts. Find the one that is like yours and you will see where the tensioner is located.

The tensioner is bolted to the engine. Since the belt is loose, remove it. Then you will need to unbolt the tensioner and replace it. Once replaced, with a wrench, you turn the tensioner so that you can reinstall the belt. When you release the tensioner, the belt will automatically be adjusted. Since the belt is somewhat damaged, I recommend you replace it too.

Let me know if I can help.
