Problem of Overheating

Hello everyone,,
Just picked up a 1997 Jetta with the gas 2.0. It has 170,000 miles. I got the thing for $150, owner said it was overheating and suspected the head gasket went bad. Anyway, it runs and drives great, but it does get hot.

I don't think it's the head gasket because the car has good power, it's a quick motor, and doesn't seem to have lost compression. Also there's no oil in the coolant and no coolant in the oil. It does not smoke out the exhaust at all.

I suspected water pump or thermostat. Pulled the pump apart, everything looked great. Pulled the thermostat out and boiled it and it opened as it should. What are my options here? Not sure what the problem could be

You may have a radiator that is plugged up. Was the PO running water only in it or proper quality antifreeze? You need to get that thing off and boiled out at a radiator shop. Or just start with a simple back flush if you have good water pressure at the hose. Stick it in the bottom and let it flow out the top. Then reverse the flow. Don't forget to do the water heater too.
