Your talking a 16 year old vehicle. When it is in ex-stream conditions the weakest links are going to give. Just have to keep up with proactive maintenance.

Coolant leaks in extreme cold are somewhat common. Usually tightening or replacing a clamp will resolve the issue. Do you have the proper mix of water and antifreeze in your truck? Frozen coolant could cause the water pump not to turn which would make the belt squeal. Frozen coolant is not good.
