Cant drive more than a few miles without overheating. Gauge goes up and car starts smoking. Radiator replaced thermostat replaced. Been to shop several times and they say no leaks. Could be gaskets but car has been doin this for months and runs perfect otherwise. Please advise. Im lost!

How hot does it get in degrees F. Are you losing any coolant? If you lose it internally won't be any external leaks. Can you check for combustion gases in the coolant?

Does the radiator fan/s work?

Just to add, as far as overheating, you intake manifold gasket among common repairs, is second only to the thermostat as far as replacement.

Did the shop do a cooling system pressure test?
