might sound like a retarded question but just wondering, My truck 2005 didnt come w/ a block heater cord, just bought one yesterday off ebay, and our temps here dont typically get below 30-35 degrees. This week though we are having them in the teens w/ wind chills in single digits. I know to yall up north that probably sounds like florida weather but my question is.......... Does it hurt the engine at all starting at that temperature w/o being pluged in and that hell raising that goes on till it warms up? Thanks
