The timing belt is NOT the cause of the squeal or the cold temp symptoms. That is the serpentine belt that is slipping. The serp belt wraps around the alternater which is causing the cold start electrical issues The are a variety of reasons that may be causing the slippage. Having said that, I do agree on changing the timing belt at your miliage, the srpentine belt will have to come off to do this.
Who ever does the job, I recommend an independent garage, preferably the one that advised you on the timing belt to do the job, a dealer is not needed. HAve the find out the source of the squeal first before doing anything. You will need to have the car there overnight so the problem haopens then. Tell them they have limited time before the noise stops.
