Well if the exhaust system is blocked it can make the engine run hot, and that would include the cat.Well if the exhaust system is blocked it can make the engine run hot, and that would include the cat.

It is more than likely your water pump. Can you run it in park with the radiator cap off. The cap on the radiator not the overflow tank. When the temp opens the thermostat you should see flow if the pump is good no flow it is probably bad. If you don't see flow check the upper hose for temp and the lower hose. If the upper line is barely warm and the lower hose is significantly hotter, it is either water pump or thermostat, but since you replaced the thermostat I would be back to water pump. BTW you should use either a contact thermometer or an infrared to check hoses, although it was done by hand in the old days.
Might want to check the catalytic converter, if this clogs up the engine cant breath correctly causing it to overheat. My guess is your fuel mileage has been going down as well.
sounds to me like you may have some leaking valves and its causing your engine to over heat. and if you dont fix this problem soon, you will cause your engine to blow. i wouldnt chance driving either.
There may be an obstruction in one of the hoses, there may be an air pocket in the system somewhere. Are you sure there is actually an overheating going on? Maybe it's a bad temperature sensor or temperature gauge stepper motor.
If you see no leaks and the fluid level is also good in the rad overflow bottle. It could be the water pump. When the car is running do you feel the hoses are hot and pressurized. Do you feel heat with your heater cranked up. The coolant may not be circulating. This would mean you need a new water pump, most likely the impeller is worn/broken inside. It can be fixed by yourself but will require some skill and time.
you have a 1.8 liter turbo engine correct? it is the water pump that is driven by the timing belt. 100% positive this is correct i have replaced countless water pumps for this reason. the reason it overheats while driving is becuase the splines on the water pumps plastic impeller are gone and it is just freewheeling on the pump shaft. at idle the pump spins slow enough to get the impeller to turn. very very very very common. replace water pump timing belt and tensioner.
Are cooling fans working? if so when they do work, the air coming through the radiator should be HOT, ROASTING AIR, if not the radiator isnt flowing coolant.how does it run after sitting all night at first start, does it run rough 5-10 seconds? if so, may have head gasket issues. BIG BUCKS........
Definitely can be the radiator.... if not take second look at that head gasket look under cap for a creamish deposit, that one sign of coolant and oil mixing. Good Luck
sounds to me like a blockage in ur pipes. its not uncommon for thermostat/ water pumps to rust out and cause problems. I would remove the return hose from radiator at home, run a hose into ratiator and flush. start motor for a minute or two and make sure you are getting flow through.
