Negative 36? I think I would be happy just having a truck that started at that extreme. You may have full capacity on the coolant, but the coolant itself may have degraded over time, when was it last flushed? Did any part of cooling system ice up? Since CEL was on, pull the codes.

Maybe the thermostat stuck open. That level of cold plays havoc with everything.

Make sure your coolant mix is rated for -40 or lower. You should probably have 60% anti- freeze - 40% water at those temperatures.
