when we start the car lately it squeals. more so now that it is colder. not so much when we have been running around and re-start the car.

Hello - the squealing noise you describe is most likely caused by a worn serpentine (accessory) belt, a weak tensioner for that belt. This causes the belt to slip under a load, and squeal as you describe. This condition will only get worse as the belt wears, until it fails - which will quickly overheat your engine. I would recommend an engine inspection to determine the source of the squeal, by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.
