Hi there. The issue is the thermostat. It is sticking about half way and not opening all the way up or it has a lot of calcium buildup. I recommend replacing the thermostat and flushing the coolant out and putting in new coolant of 50/50 mixture. If you need further assistance diagnosing your coolant issue, then seek out a professional, such as one from YourMechanic, to help you with your vehicle.
