Re: Cold start howl/squeal
Yep, any time it's very cold out. Which here in Canada happens pretty much all winter long. Most days I start it from the garage, so it isn't cold enough to do it. But if it's been parked outside overnight, or has sat outside in my office parking all day when it's very cold, yup. Exactly as you describe it. Only lasts 3ish seconds.
I've never bothered to follow-up on it.
