hose or metal pipe is rusted they can go. but could be the water pump on some models.

water pump ? or a heater hose ?

I would think you have a badly leaking engine cylinder head gasket. Have a shop test for that.

look at the anti-freeze and if its green you can use any green anti-freeze if its orange then you will have to use long life anti-freeze that is compatable with other long life coolant.

You should have your coolant pressure check it will reveil any small leak that you my not be able to see.

LEAKING OUT ANTIFREEZE AT THE WEEP HOLE IN WATER PUMP..YOU HEARING ROARING LIKE NOISE DRIVE.BELT WILL SQUEAL MEANING PUMP BEARING LOCKING UP.AND YOUR CAR WILL OVER HEAT.

the brown milky stuff is rust and you have mixed two different types of antifreeze together it formed a reaction,you will need to do a complete flush and top up with the correct antifreeze for your engine asap.DO NOT MIX ETHYLENE GLYCOL WITH ANY OTHER TYPE OF ANTIFREEZE..........

Not only the cap, but you have to find the drain. They are usually put in the most difficult places. After ten years consider having your system flushed, it'll be good for your radiator. Take the car to a jiffy-lube type place and they will change your oil for you too. The Taurus is a good car, treat it right and it will give you good service.
