car won’t start - Common Sense Home

If your car won't start in the cold, the best solution combines proper maintenance and options to make a cold start easier on your vehicle. In northern Wisconsin, cold winter weather is a fact of life. My 2007 Saturn Ion starts in weather as cold as -25°F actual temp without fail, without any special treatment. (But not everyone is so lucky.) We have a fleet of trucks at work (both diesel and gas) that run in all kinds of weather. I’m drawing on my experience working with them, and from full time mechanics that help troubleshoot when we need them.
