On a 2003 Ford Ranger : The 2.3 litre four cylinder engine has a thread on cap on the engine coolant reservoir , that is the pressure cap / radiator cap ----------------------------------------------------------------------------------------------------- On the 3.0 and 4.0 litre V6 engines , I believe there is a radiator cap on the top of the radiator , but with the engine cool you should add engine coolant to the engine coolant reservoir - it has a cold fill mark
there isn't a radiator drain plug. you have to remove the lower radiator hose from the radiator to do a drain and fill.
I guess thru the overflow container.
Fill it to within4 inches of the top and you will be good.

On the lower reservoir of the radiator. You should be able to see it looking from under the hood on the driver's side.
Is there a cap on the top of the radiator?
Well, honey, first you gotta locate the radiator cap on that old Taurus. Make sure the engine is cool, 'cause you don't wanna burn yourself. Slowly twist off the cap, pour in a mixture of coolant and water until it reaches the top, then twist the cap back on. And voila, you've just topped off the radiator of your 2001 Ford Taurus.
Take radiator cap off, fill radiator with coolant, put cap back on!
