Have a 99 ranger. That is over heating. Heater core, thermistat, and belt has been changed, as well as sencer. It is still over heating. I now smell antifreeze in the exhaust pipe. I have flushed the radiator, and replace the cap. There is no water in my oil. Any ideas

You may need to replace the radiator, due to corrosion and/or phosphate scale. Afterwards, refill with a 50/50 mixture of recommended antifreeze and distilled water. These links may help:

Ensure you can feel the rush of coolant, from the water pump, when the top radiator hose is squeezed.
