how to drain 1999 windstar
you can either pull the hose for it or you can usually just open the drain plug on the radiator
On the 2002 Windstar there is a 3/8" square head antifreeze drain plug above the starter. This drains the left bank of the block and can be replaced with a 1/4" pipe valve.
The 2001 Windstar has no radiator cap. It has an antifreeze bottle.
According to the 2000 Ford Windstar owners manual : It came from the factory with a 50 / 50 mix of distilled water and GREEN colored antifreeze ( meeting Ford specification ESE-M97B44-A ) * Ford states to not exceed 60% antifreeze in the mix *
( 5W-30 ) is the preferred engine oil , according to the 1996 Ford Windstar Owner Guide
On a 1996 Ford Windstar : Under the dash on the drivers side , not too far from the inside hood release
i dont know whwere is the tachometer wire of 2001 ford windstar
I would recommend you drain it out, flush the system, and install the correct green coolant that Ford recommends. Using the wrong coolant can damage parts.
