SOURCE: Radiator blockage?

I believe you have a head gasket blown or a cracked head. When you start it up COLD with the cap off, it would push water out immediately. Fill it with plain water and try this. It might not be a bad idea to perform a pressure test too. Also check for antifreeze in the oil. It will get milky looking and might even be over full. If this happens after warm-up, you may just have a plugged radiator. Have it professionally cleaned. The water pump vanes could also possibly be corroded off and it's not effectively displacing coolant. Hope this helps.

SOURCE: where do you fill radiator on 02 taurus ses?

YES. But dont overfill it. Slowly add coolant to the low full line and let it run a while, like 10 minutes. if the level goes down fill it to the full line. After it cools for 30 minutes recheck the level and add as needed.
