Is thermostat good?

So if it just sits and idles it never gets hot? Are radiator fins blocked/dirty?

I have replaced the thermostat and took the radiotor to a radiator shop where it was pressurized because it was partially clogged. I have replaced the radiator cap as well; but it still gets hot. I can drive for about 15-20 mins before it starts getting hot; than the temp goes down for a few mins than the temp starts rising again. But as soon as I stop and leave running the temp goes down. For some reason it only rises while driving and decreases while sitting in drive/idle. Not sure what that can be; any suggestions?

Have you pressure tested system? If you operate heater will that stop overhaeting?
