First question is how hot did you get the engine? Diesel engines are not like gas engines, if you overheated it too bad, it will ruined, the easiest way to determine that is how easy it starts up. If it starts up the same before you overheated it, is probably okay, if it's hard to start "Houston we got a problem" before I move any further, let's try to diagnose this;
1. The first thing I want you to do, is removed The radiator cap, start up the vehicle, look inside the radiator reserve tank, and tell me if you see a little stream of water flowing from the small hoes looked up to the reserve tank.
2. If there is no water flowing into the tank you have a bad water pump.
I need to know these things before I can direct you any further.
