Thank you for your answers. My air filter housing has wires running across the top of it. Do these disconnect easily? The Geo is basicly a Toyota Corolla. I found a you tube video for a Toyota Corolla for these same years. It does seem to take some work to remove the thermostat. According to the video, it is a 3 out of 4 in difficulty. But in that video, I did not see the same wires on top of the air filter housing.
