Yesterday while driving home from work in heavy snow my service engine light came on and the i noticed my engine temprature was on the maximum and after i shut it off and started again it kept going up every 3 miles or so ,i took it to a local franchise and the said there was nothing wrong and the only trouble code was engine overheatin ,i drove it for 30 minutees today and it did not overheat could this be like a one time incident maybe my thermostat getting stuck or something,head gasket seems okay i dont see any white smoke ,coolant level was okay does somebody have any opinions and i not very knowledgable about cars either
Thanks in advance
