Hi there. Typically when this occurs it is because there is a cooling system issue with the vehicle. It can be an issue with the coolant being low due to a leak or it can be caused by an issue with another part of the cooling system. The fact that it appears to be getting rally hot right now it needs to be checked as soon as possible. Hopefully there is not any engine damage at this time. I usually start by checking the coolant level and then diagnosing it from there.
