You can replace the radiator yourself, but why do you need to? The thermostat is on the engine. Follow the large hose that goes to the engine block....not the water pump. The thermostat is under that or sits on the top of the engine....looking for a pic for you!

Firstly, ensure you have the required 'mixture' of coolant/water (must have required coolant).
Second, I would recommend you re-test all the cooling system sensors again (make sure they're within specifications), in case a new one is faulty.
Third, ensure the new thermostat was of the correct temp setting (they all differ), so that it opens at the required time. Most cooling systems operate within 90 - 100degC.
Fourth, make sure the radiator (and associated hoses) aren't blocked.
If your temp gauge is reading higher than normal, but NOT in the danger zone...then this can be considered normal (especially if you've replaced with new components) and nothing to be concerned about.
However, if the temp gauge IS in the danger zone....then this suggests the coolant is not flowing through the cooling system properly.
If all above components test ok, then it's possible your water pump may not be pumping enough volume.

Testimonial: "I appreciate your help...Maybe I should just relace the water pump, that would be the last thing that I would need to replace."
Check to see if the radiator fan relay has gone bad and needs to be replaced. Once you located the relay, (in the fuse box under the hood) Try swapping it out with another relay and see if the fans stop, if the fans stop working with the swapped relay, replace the relay. It's know for the relays when they go bad to stick and will have a close loop. Good luck and hope this helps. Keep me posted, be glad to help you get your car running 100% again soon.
