Toyota Corolla 2.0D engine experiencing overheating

I recently bought a 2001 Toyota Corolla 2.0D with a 2C diesel engine. Since I had owned the same car before, I was familiar with some maintenance requirements. Today, I changed the timing belt because I wasnt sure if the previous owner had changed it, and the car had 124,000 miles on it and was previously owned by someone who had taken good care of it.

However, I discovered that the radiator wasnt very clean and the thermostat valve wasnt working. I replaced the thermostat valve with a new one I had bought, but the car started overheating when I drove it away from the mechanics shop. I managed to drive it home, but the temperature gauge went all the way up to the H mark, so I think the new thermostat valve remained closed.

I plan to remove the faulty thermostat valve tomorrow, but Im concerned if I need to worry about the engine o r head gasket. I would appreciate an experts advice on this matter.

It seems that when installing a thermostat, its important to position the jiddle/dudder valve at the top and then purge the air from the system while allowing the engine to idle and warm up. However, the person who provided this information may not be aware of current radiator cleaning practices and may have overlooked the cooling channels in the engine. Its possible that they have outdated knowledge and may not be as knowledgeable about modern cooling systems.
