Hello, I'm having issues with overheating, i have replaced the radiator, both thermostats, the water pump, and heater core. However, it's still overheating I've also done a compression test on all four cylinders and they checked out to be okay. What do i do next?

Hello,

Do you know if the cooling fan is operational?
With the engine running at operating temperature the fan should come on.
If the fan is not coming on the engine will overheat as well.
An inoperative fan could be due to a relay or a faulty coolant temperature sensor that is not sending the proper signal to the ECM. Or it could be a bad fan.

Let me know if the fan works.

Also are there any other symptoms you are noticing? Does it smoke?

Any questions please feel free to let me know.
Thank you.
