Changed thermostat ,changed water pump and he still says it is overheating

You put in the sealer and the stop leak may have blocked some of the radiator and heater cores causing the overheating. I would recommend flushing out the system with radiator flush and then refilling and testing it to see if the radiator has proper flow or needs replaced. If you want to have this checked, a certified technician from YourMechanic can come to your car’s location to inspect the overheating issue and determine what needs repair.
