To better assist you if you need to get back with me please let me know what the 8th digit of your VIN is.
Next, you have 170K on the car so I need a little more info on your vehicle.
Have you been using Dex-Cool as your antifreeze?
Both of your radiator cooling fans, are they running when you select A/C?
When was the last time you had your thermostat changed?
Does your heater work okay?
Have you ever changed your water pump or radiator?
Last, just in case your car threw a code, please go to Auto Zone (AZ) or O'Reilly's (OR) and for FREE they can pull the codes to the car. Most important: Once they check your codes, if they find something and you don't get it fixed and need to get back with us, please make sure you tell us exactly what the code was, number and all. Example, if the code was E0568 O2 Sensor bad. Then make sure you give us all of that. While there for FREE also they can bring their tester out and check your battery, alternator and starter.
My first thought is if you have been using Dex-Cool as an anti freeze your system is blocked and needs flushing. I would change the thermostat and definitely flush the system really good. You may have to replace your radiator and in time your heater core.
If you would answer the above and I can offer better advice.
