Re: Load squealing on startup when very cold out
It is likely the power steering pump. When very cold, the fluid isn't as viscous, and the pump struggles to get things circulated.
There was a re-design of the power sterring fluid resevoir to try and alleviate this concern, but I honestly haven't noticed much of a difference between the old and new - mine'll still complain first start on a cold day.
I would say if it only lasts a few seconds, and only happens when really cold, it is "normal"
