I have a 2005 and he's been unplugged all winter. It is January 20th and has only been started three days (the past three days) since august. I didn't have a problem until this morning. The little guys was trying so hard. But couldn't keep his engine running. Do i need a block heater and if so what kind? Also, today is supposed to be a wind chill of-50... does the wind chill effect him?
