Hello,
The engine can overheat due to a number of reasons.
It could be due to having low coolant, a stuck closed thermostat, bad radiator, faulty water pump, contaminated coolant or having blockage in the cooling system. It can also overheat due to inoperative cooling fans.

Do you know if the cooling fans are operational?
Inoperative cooling fan will lead to overheated engine. The cooling fans might not work due to a bad fan relay. It can also be due to bad wiring or malfunctioning fan motor.
Checking the relay should be the first step.

Keep in mind that a faulty temperature sensor will also prevent the fan from turning on.
