First I would check your coolant level. Let your vehicle cool down and look in your coolant pressure tank. It should have a mark that tells you where the full level is. If it is low you have a coolant leak that needs to be fixed. If the coolant is full the most likely cause is a failed thermostat. This is a valve that regulates the temperature of the coolant by opening and closing at a certain temperature. If the thermostat gets stuck closed the coolant will not flow through the radiator and cool your engine down. I would suggest you get some help from a mechanic to find the root cause of your overheating issue.
