Overheating

The car had overheated due to a fan motor. Replaced the motor.

but it still overheats. I think its either a heat gasket or cracked head. Anyway to tell without removing the head. Im trying not to put much money into the car.

There is no coolant in the oil.

I have not tested the coolant for the existance of hydrocarbons.

you may have just enough of a crack in the gasket to let pressure out but fluids not back in, it happened to mine. do you hear a boiling sound when you shut the car off? but see no loss of coolant, or see any oil on the coolant? mine would just bubble and that's it. until I got no heat in the car on a cold winters day.
