Hi, this is Bo, an auto expert on RepairPal's Car Genius team! You've swapped out the thermostat, but your MKZ is still overheating faster than a cat on a hot tin roof. That code P0304 means you've got a misfire in cylinder 4, which might be throwing more heat into the engine. Now, if it's not leaking coolant but was burning it before, you might be dealing with a head gasket issue. A compromised head gasket can let coolant sneak into the combustion chamber, causing overheating and that lovely burnt coolant smell. Also, check if the radiator is clogged or if the water pump is circulating coolant properly. It’s like having a treadmill with a broken belt—no matter how much you try to run, you’re going nowhere fast.
