It has been suggested in various posts that an improperly installed thermostat can cause heating issues. I'm no mechanic, so don't know. Maybe someone on the Spyder assembly line installed them wrong - while another person installed them properly hence the vast differences there are between various 2013 RT's. Just wondering. Wouldn't that be great if it all boiled (pun) down to such a simple fix!!
