Hi again: I have written before of not being able to get drain loose on the radiator on our 99 Zetec. I could see the drain plug but couldn't get a tool in place to turn it. Well, today I removed the right side, lower radiator support bracket (two, 8 mm fastners hold it in place.) With the extra room I was able to turn the drain plug with slip joint pliers. After 46,000 miles, the antifreeze no longer looked like fresh Prestone. I put silicon grease on the treads before tightening the drain plug.
