Hello,
This sounds like your vehicle's thermostat could be sticking closed. Your vehicle has a thermostat in it that acts like a gateway, opening when the coolant reaches a certain temperature and allows the coolant to be able to flow around the engine cooling it. It then closed again and the whole process starts over. This is done to keep the coolant hot enough to heat your vehicle's heater and defroster. Here is a generic guide on how to change a thermostat below:

I have included in the diagrams down below I have included the Original Equipment Manufacturer[OEM] part number and the instructions for the removal and installation of the thermostat for your vehicle from the vehicle manufacturer. Please go through these guides and get back to us with what you are able to find out.
Thanks,
Alex
