97 running hot

I replaced the engine, radiator, and thermostat on a 97 mustang gt but it's still running hot. Can anyone help?

Verify that the cooling fans are coming on.

Does it get hot all of the time? Highway driving? City driving? Idling?

Make sure you're not making coolant

Check your fan fuse and relay. Or the fan itself.

Almost every reply here could be the reason for your car running hot bro, here are a few more options:

Make sure your drive belt is not old/ or dry rotted and about to break
Another one could be the water pump is about to go out
fan cluth
heater core needs to be replaced or flushed

Now they are saying it's building too much pressure. Why would that be?

The person that put the engine in did block the heater coil. Could that be it?

Yes if he didnt connect the heater hoses together to complete the circuit that will cause it to overheat.
