There are two main causes of hot engines. The first & easiest to fix is the thermostat. These are cheap & are easy to replace. Get one that will fail in the open position. You should be able to replace one of these for less than $20.
If you remove or replace the thermostat & it still runs hot (more than 200 degrees) you have a radiator that needs to be cleaned or poor airflow. Usually if a rad has run water for some period of time scale will build up on the inside & prevent it from cooling.
You can buy a new rad or find a local shop that will boil it off & clean it out. The local shop way is usually cheaper.
