A while ago I asked about how frequently one needs to run a car so that the a battery will not run down. I had let our car (a 1995 Chrysler Concorde) sit for about 10 days and then when I went to start it, it wouldn’t turn over. The guys at the garage said that nothing was wrong with it: that some older American cars simply need to be run every 4 days or so. But I’ve heard other people say that this is crazy: that they let their car sit for two or three weeks and it starts right up.
Here is my current question: recently the car’s thermostat went and we have gotten it repaired. Could the thermostat problem and running too hot have been connected to the fact that if the car sat for more than 4 or 5 days it wouldn’t start? I can’t see how these could be connected, but is it possible?
