Socket wrench wouldn't work and neither would a open end wrench for the back bolt closest to the firewall, that was my problem. I picked up a Gear Wrench by Craftsman which is an open end wrench on one end and a closed, ratchet on the other side. That closed, ratchet side worked perfect to get in that small area and get that other bolt out of the thermostat hosuing. I ended up draining the coolant, flushing the whole system with a hose, putting in a new thermostat, and finally refilling the coolant. After I got everything finished up, the problem was solved with the new thermostat. My car heats up quicker and stays consistent on temperature like it should. Now I just need to install the new fuel filter that I have had sitting in my room for 6 months........
