My toyota 1NZ-FE engine is overheating.I have done the following but do not seem to be near a solution
1)Replaced the thermostat
2)Replaced cylinder head gasket after head being tested and machined
3)replaced radiator cap.
3)Checked radiator for leaks

The engine overheats causing the coolant to fill in the reservour and spill out through the overflow.
Does this mean the radiator is faulty?When I test the vehicle without the thermostat and the radiator cap off the fluid is thrown out when the vehicle is idling.What else can I check for failure?
