If the vehicle is overheating there are a couple things that could be wrong.
The fluid is low, there's a clog in the system somewhere preventing the coolant from flowing, there's air in the system, or the thermostat is not working properly.
Have these things checked first. You don't want the vehicle to over heat because this could create costly engine repair issues.
