This is probably more of a general automotive question. Yesterday, my thermostat on my 1983 Ciciv wagon seem to have quit. Fortunatly, I keep basic tools with me and I was less than two miles from a automobile parts store. So bought, and replaced, the thermostat and went about my day. My question is, had I not had acess to the part so readily could I have just removed the thermostat and driven without until I coudl have gotten the part?
