It is called the Windshield Washer Fluid Resevoir.
you have to remove the plastic cover under the fender, after you should be able to figure it out. it's very simple.
You can replace it. Or you get a plastic tank fix kit in AutoZone or Advance Auto Parts.
I am going to presume you mean the windscreen washer. The best fix is to just replace either one that is leaking. The "bottle" is usually made of plastic and is pretty hard to repair with any certainty that it will not leak again.
The windshield washer pump for the ford aspire is on the side of the washer fluid jug which is located on the drivers side at the front of the car. To access it, you must remove part of the plastic inner wheel well just in front of the drivers side tire which is fairly easy. I was able to access it by removing only 3 small screws and then pulling the plastic wheel well back. From underneath the car, just in front of the front drivers tire, reach up and you can disconnect the electrical connection and then slide the pump out from the side of the washer jug. It is only held in by a rubber seal. Fairly quick and easy job.
Inside the cargo area , drivers side , near liftgate , behind removable plastic panel with the rear windshield washer fluid container
A drain plug washer is not necessary unless you have oil leaking from the drain plug.
Assuming it's the same as on the 4 door : Open your rear liftgate , and you will see a rubber plug on the drivers side above the taillight lense , that is where the rear washer fluid is added . I like to remove the plastic panel inside the cargo area on the drivers side so I can actually see the washer fluid tank ( where the wheel jack is located )
undo the inner plastic wheel arch on the drivers side and the valve is located above the washer bottle
On ours, it is behind an access panel in front of the RH tire.
Open the rear liftgate and above the left tail light you will see a rubber fill plug The plastic reservoir is behind the plastic panel in the cargo area on the drivers side , by the liftgate , where the wheel jack is stored - if you remove the trim panel you can see the washer fluid level
lift bonnet and locate a black plastic ( triangular shape ) grill under passenger side window wiper, when opened the top of washer bottle is there, i did remove the gauze filter from the neck of bottle as the washer fluid and water took ages to pass into it. under the drivers side window wiper is another plastic grill of the same where the car jack is kept. hope this helps. mick.
1) There is a plastic reservoir where you fill with coolant, that sometimes will have a crack at the bottom, or the hose coming from the reservoir. It also holds water for your wiper washer fluids. 2) Radiator core is leaking and will move down the frame of vehicle. 3) Driver side head gasket leak.
