Still overheating after replacing the water pump, thermostat, radiator cap, top hose and flushed the radiator?

Good afternoon.

From constant overheating, you may have damaged a head gasket. Head gasket failure is a result of overheating. You may have found the original reason for the overheating but in the process, it may have damaged a head gasket.

To confirm, you need to do a leak down test. That is where you inject air into each cylinder and watch for any movement in the radiator. That will confirm whether you have a failed head gasket. You can rent a tool at a parts store for this test.
